At the beginning,the inertial measurement unit is an electronic device that measures and reports on a craft's velocity, orientation, and gravitational forces, using a combination of accelerometers,gyroscopes, and magnetometers. Now IMUs are commonly used in the Humancomputer interaction(HCI), navigational purposes and balancing technology used in the Segway Personal Transporter as we all know.

The MPU-6000/MPU-6050 family of parts are the world’s first and only 6-axis MotionTracking devices designed for the low power, low cost, and high performance requirements of smartphones, tablets and wearable sensors.

The MPU-6000/6050 devices combine a 3-axis gyroscope and a 3-axis accelerometer on the same silicon die together with an onboard Digital Motion Processor (DMP) capable of processing complex 9-axis MotionFusion algorithms. The parts’ integrated 9-axis MotionFusion algorithms access external magnetometers or other sensors through an auxiliary master I2C bus, allowing the devices to gather a full set of sensor data without intervention from the system processor.

The 6 Dof sensor breakout integrate with the MPU6050 sensor and the low noise 3.3v regulator and pull-up resistors for the I2C bus. So it's available to directly hook up the sensor with the Arduino processors for your robotics,HCI and wearable projects. With the Arduino library from i2cdevlib it's easy for you to drive this sensor and get the pitch,roll,yaw,quaternion,euler data.

Extend your light-sensing spectrum with this analog UV sensor module. It uses a UV photodiode, which can detect the 240-370nm range of light (which covers UVB and most of UVA spectrum). The signal level from the photodiode is very small, in the nano-ampere level, so we tossed on an opamp to amplify the signal to a more manageable volt-level.

This sensor is much simpler than our Si1145 breakout, it only does one thing and gives an analog voltage output instead of requiring a complicated I2C setup procedure. This makes it better for simple projects. It also has a 'true' UV sensor instead of a calibrated light-sensor. To use, power the sensor and op-amp by connecting V+ to 2.7-5.5VDC and GND to power ground. Then read the analog signal from the OUT pin. The output voltage is: Vo = 4.3 * Diode-Current-in-uA. So if the photocurrent is 1uA (9 mW/cm^2), the output voltage is 4.3V. You can also convert the voltage to UV Index by dividing the output voltage by 0.1V. So if the output voltage is 0.5V, the UV Index is about 5.

Please note, our UV LEDs are 400nm, outside the range of this sensor, so if you're trying to test this sensor, don't use them! A UV tanning lamp or 'lizard-lamp' will work much better.

Bluno Beetle is another milestone in wearable electronics device area, which makes DIY users have more options in the project design. It is fully compatible with Bluno in instructions and procedures, supporting Bluetooth HID and ibeacon modes.

And it not only supports USB programming, but also wireless programming method. With the V shaped gilded I/O interface, it is convenient to screw conductor wire on it, which could a good choice in the wearable market.

Home is where the heart is...it's also where we keep all our electronic bits. So why not wire it up with sensors and actuators to turn our house into an electronic wonderland. Whether it's tracking the environmental temperature and humidity in your laundry room, or notifying you when someone is detected in the kitchen, to sensing when a window was left open, or logging when your cat leaves through the pet door, this board is designed to make it way easy to make WiFi-connected home automation projects.

The main processor is the ESP32-S2, which has the advantage of the low cost and power of the ESP32 with the flexibility of CircuitPython support thanks to native USB support. There's also Arduino support for this chip, and many existing ESP32 projects seem to run as-is. Note this chip does not have BLE support, but for WiFi projects its great. You can use it to connect to IoT services or just the Internet in general, with SSL support and this module has plenty of PSRAM for any kind of data processing.

The board is designed to make it easy to wire up sensors with little or no soldering. There are built in sensors for light, pressure, humidity and temperature sensors. Three JST PH plugs allow for quick connection of STEMMA boards that use digital or analog I/O, and there's a STEMMA QT port for any I2C devices.

We can divide temperature measurement in to two types: contact and non-contact. Contact measurement can only accurately measure temperature when the testing object and the sensor reach thermal equilibrium. This can mean longer response times and reading inaccuracies offset by ambient temperature. By contrast, non-contact measurement uses infra-red radiation to measure the temperature and does not require a direct touch. Additionally, this method of measurement can be read quickly and accurately.

In recent years non-contact measurement methods have been used for medical, environmental monitoring, home automation, automotive electronic, aerospace and military applications.

Our latest infrared temperature measurement module is the MLX90614. This module measures the surface temperature by detecting infrared radiation energy and wavelength distribution. The IR temperature probe consists of an optical system, photoelectric detector, amplifier, signal processing and output module. The optical system collects the infrared radiation in its field of view and the infrared radiation energy is converted in to corresponding electrical signals when converging on the photoelectric detector. After being processed by the amplifier and signal processing circuit, the signal is converted in to a temperature value. The MLX90614 is self calibrating and has a low noise amplifier integrated in to the signal processing chip. The chip itself is a 17-bit ADC and DSP device, giving accurate and reliable results.

Tracks can be controlled via 16 programmable trigger inputs, or by using a native serial control protocol or even MIDI.

Trigger inputs can be connected directly to switches and buttons, or to digital outputs from sensors or another microcontroller. Alternate functions can be specified using a free cross-platform GUI application, and allow triggers to play sequential or random tracks, pause and resume groups of tracks and even control volume. An Arduino library allows for complex serial control like real-time mixing, starting multiple tracks in sample-sync and smooth cross-fading between tracks.

On-board sample rate conversion allows for smoothly changing playback speed/pitch from 0.5x to 2x. in real-time.

MIDI allows you to use the WAV Trigger as a polyphonic sampling synthesizer to play your own sounds from any MIDI keyboard controller. MIDI Channels and Note numbers are mapped to track numbers, and MIDI Controllers adjust volume as well as attack and release times. MIDI Program Change is supported to switch between up to 16 banks of 128 sounds. The WAV Trigger audio engine even implements, pitch bending, voice stealing (oldest playing voices are used for new MIDI Notes when all 14 voices are being used), note attack (fade-in), note release (fade-out) and latency averages 8 ms.

Raspberry Pi's Raspberry Pi 5 is built upon a 64-bit quad-core 2.4 GHz Arm® Cortex®-A76 processor, which can provide a two to three times increase in CPU performance compared to Raspberry Pi 4. This is also complemented by a substantial improvement in graphics performance from an 800 MHz VideoCore VII GPU, which provides dual 4Kp60 display output over HDMI and state-of-the-art support from a rearchitected Raspberry Pi image signal processor, providing a much better desktop experience and creating opportunities for new applications for industrial customers.

Along with being built on an updated processor, Raspberry Pi 5 also includes an entirely new chip designed in-house by Raspberry Pi to handle the majority of I/O capabilities. The RP1 Southbridge delivers an upgrade in peripheral performance and functionality. The USB bandwidth has more than doubled, leading to faster transfer speeds to external UAS drives and other high-speed peripherals. This chip has also enabled Raspberry Pi to a pair of four-lane 1.5 Gbps MIPI transceivers, which triples total bandwidth and supports any combination of up to two cameras or displays. The RP1 also doubles the SD card performance via the SDR104 high-speed mode. Lastly, the RP1 also added the opportunity to add a single-lane PCI Express 2.0 interface that supports high-bandwidth peripherals.

In addition to the RP1 chip, a power management IC from Renesas enables additional features. Raspberry Pi 5 now has an onboard power button, which enables the user to power on/off the board with just a touch. This PMIC also includes an onboard RTC. In order to add a battery backup for the RTC, Raspberry Pi has added a connector for a battery connection. The last feature of the PMIC is the ability for the board to recognize when a Power Delivery (PD) power supply is used and enables a higher output of 1.6 A to the USB ports. If a non-PD power supply is used, the ports are limited to 600 mA.

Raspberry Pi 5 has two new connectors: one UART connection for their debugger board and one for a fan connection. These connectors make the connection of the debugging probe, the case fan, or the active cooler quick and easy.

The kit comes pre-certified to FCC, CE, IC, KC, and MIC wireless regulations, and supports a host of sensors to help you get prototyping in no time.

Bosch has stepped up their game with their new BME280 sensor, an environmental sensor with temperature, barometric pressure and humidity! This sensor is great for all sorts of indoor environmental sensing and can even be used in both I2C and SPI!

This precision sensor from Bosch is the best low-cost sensing solution for measuring humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuraccy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with  ±1 meter or better accuracy!

Breathe easy with the SGP30 Multi-Pixel Gas Sensor, a fully integrated MOX gas sensor. This is a very fine air quality sensor from the sensor experts at Sensirion, with I2C interfacing and fully calibrated output signals with a typical accuracy of 15% within measured values. The SGP combines multiple metal-oxide sensing elements on one chip to provide more detailed air quality signals.

This is a gas sensor that can detect a wide range of Volatile Organic Compounds (VOCs) and H2 and is intended for indoor air quality monitoring. When connected to your microcontroller (running our library code) it will return a Total Volatile Organic Compound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) over I2C.

AI is pervasive today, from consumer to enterprise applications. With the explosive growth of connected devices, combined with a demand for privacy/confidentiality, low latency and bandwidth constraints, AI models trained in the cloud increasingly need to be run at the edge.

At the heart of the kit is, of course, a Renesas S7G2 MCU, a 240 MHz Arm Cortex-M4 with a floating-point unit (FPU), 2D drawing engine, up to 4 MB of Flash and 640 KB of SRAM. The performance of the S7G2 not only helps drive a 2.4" QVGA TFT LCD on the board, it also enables capacitive touch sensing. Alongside IEEE 1588 Ethernet PTP, CAN, RS-232/485, this makes the SK-S7G2 starter kit a great place to start for industrial, consumer white goods, and other applications that require both human-machine interface (HMI) and deterministic connectivity. Last but not least, the Synergy Software Package that comes with the kit gives you all of the development tools and hardware abstraction needed to get off the ground quickly. For example, Express Logic's ThreadX RTOS, GUIX development libraries, file system, and e2 Studio are all at your fingertips with the SK-S7G2.

SparkFun has teamed up with CircuitDojo to bring you the SparkFun nRF9160 Thing Plus, featuring the powerful Nordic nRF9160 microcontroller in a Feather-compatible footprint. This little chip is capable of both CAT M1 LTE and NB-IoT cellular communication and is designed to work with Zephyr, the go-to RTOS for embedded development. To make the Thing Plus even easier to use, this board utilizes our handy Qwiic Connect System which means no soldering or shields are required to connect it to the rest of your system!

Not only can you take advantage of Nordic’s advanced power states, but you can also put the device into a low power standby state. Laboratory measurements are putting that mode at about 2µA of current. 2µA! It also features a 3.3V Buck-Boost which helps get every mWh from your batteries as possible.

No batteries? No problem! Power your nRF9160 Thing Plus externally with a USB-C cable. Keep it on at all times for high availability scenarios.

Want to persist data? The nRF9160 Thing Plus has a 4MB external flash for storing data while offline. Using external flash with a filesystem like LitteFS and you’ll have a project to recon with!

A postage stamp sized RP2040 development board with a USB-C connection and 8MB of flash, perfect for portable projects, wearables, and embedding into devices.

While we love the Raspberry Pi Pico we also wanted something smaller and with a bunch more flash on board. Introducing the Tiny 2040 - a teeny tiny powerhouse with the chops to realise truly ambitious projects.

Powered and programmable via USB-C, Tiny 2040 comes with 8MB of QSPI (XiP) flash on board so it can handle projects small and large with ease. The board is designed with castellated pads to allow it to be directly soldered onto a PCB or alternatively you can use pin headers to hook it up on a breadboard or directly with wires. We've even managed to fit in a programmable RGB LED, a reset button and some clever circuitry that lets you use the boot button as a user controllable switch.

It's compatible with firmware built for the Raspberry Pi Pico but offers a reduced number of pins due to its size. You can even run MicroPython on it!

The UDOO x86 Ultra is one of very few Intel-based development kits available to the embedded engineering market, and showcases a 2.56 GHz Pentium processor with Intel HD Graphics 405 – featuring 16 execution units. This kit in particular features an enclosure, but within it are interfaces to all sorts of multimedia-centric ports, particularly display interfaces that pair with the Pentium to drive multiple simultaneous displays in applications like digital signage. Ethernet and wireless slots also allow you to interface this gateway-class device with the rest of the world.

This guide will show you how to use an MCP2221(A) to connect to I2C sensors and breakouts from your desktop PC running Windows, Mac OSX, or Linux. The MCP2221 also allows for general purpose digital input and output (GPIO) for things like buttons and LEDs, analog to digital conversion (ADC), and digital to analog (DAC).

The cool part about this is that you can then use any of the CircuitPython Libraries that have been written for the numerous I2C sensors and breakouts. You can bring that data directly into your PC for any kind of powerful analysis or presentation.

The VIM1 is the original Amlogic S905X Arm development board designed by Khadas for hobbyists, makers, and electronic fans; many refer to it as an "Open Source TV Box." It is slightly smaller than a Raspberry Pi with dimensions similar to that of a credit card. The VIM1 is only available in two versions: VIM1 Basic with 8 GB EMMC storage and AP6212 (b/g/n) Wi-Fi, and VIM1 Pro with 16 GB EMMC storage and AP6255 (b/g/n/ac) Wi-Fi. Both versions have 2 GB of DDR3 RAM and Bluetooth® 4.2.

Just like a familiar desktop computer, the VIM1 single board computer supports the booting of multiple operating systems. Users can choose from a variety of OS images (ROMs) from their documentation or community forum. Popular OSes include Android 7.1/8.0, Ubuntu 18.04, LibreELEC, Armbian, and Buildroot. There are even dual-boot images for developers to boot both Android and Ubuntu from the same EMMC.

Developers will also find a built-in 40-pin GPIO, real-time-clock (RTC), and V_IN port for an extra power supply. In addition, the three user-buttons on the side provide easy access to power, reset, and function keys. Full open source code is available on GitHub, and hardware schematics can be found in their documentation. There is also a built-in power control unit for supporting power-cycling via remote control.

In comparison with the Octa-Core Amlogic S912 SoC in the VIM2, the S905X SoC in the VIM1 generates significantly less heat output. This makes the VIM1 especially useful in environments that only support passive air convection for heat dissipation rather than forced airflow. In many instances, a single heatsink is sufficient and some people may even find a heatsink unnecessary for their application.

These low-power-laser-based time of flight sensors have great accuracy and sampling frequency, and this particular sensor has a wide range of detection, from 4cm to 4 metres.
