MYIR Introduces $29 ARM SoM Powered by ST STM32MP1

The MYC-YA157C CPU Module is a powerful and low-cost SoM for various embedded applications.

MYIR introduces a MYC-YA157C CPU Module powered by ST's STM32MP1 microprocessor featuring dual-core Arm Cortex-A7 operating at up to 650MHz and an embedded Cortex-M4 core operating at up to 209MHz.

The module is ready to run Linux OS and targets applications like industrial control, consumer electronics, smart home, medical and other energy-efficient applications for performance and low power.

Measuring 45mm by 43mm, the MYC-YA157C CPU Module is a compact System-on Module (SoM) that combines the STM32MP157 processor (STM32MP157AAC3 by default), a dedicated Power-Management IC STPMIC1 also from STMicroelectronics, 512MB DDR3, 4GB eMMC as well as an integrated GigE PHY chip.

A number of peripherals and IO signals are brought out through 1.0 mm pitch 164-pin stamp-hole (Castellated-Hole) expansion interface to make the module an embedded controller for system integration.

MYIR offers MYD-YA157C development board for evaluating the MYC-YA157C CPU Module, its base board has explored a set of peripherals and interfaces such as:

  • RS232, RS485
  • USB Type-C DRP
  • USB2.0 HOST
  • Gigabit Ethernet
  • WiFi/Bluetooth
  • CAN
  • Micro SD Card Slot
  • JTAG, RGB888 based LCD/ HDMI, MIPI-DSI, etc.

The MYD-YA157C is delivered with optional MY-CAM002U Camera Module and MY-TFT070CV2 LCD Module for evaluating and prototyping based on ST's STM32MP1 microprocessor.

MYIR also offers design services to customize the base board according to customers' requirements. Different SoM configurations such as other STM32MP1 CPU models, RAM or Flash configurations, industrial or commercial grade can also be customized.

Based on Linux 4.19.9 kernel, MYIR has provided software resources for Yocto 2.6 based MYIR MEasy-HMI system, Yocto 2.6 based ST Weston system, Ubuntu 18.04 system and MYIR MEasy-IOT system including kernel and driver source code, STM32CubeProgrammer and STM32CubeMX tools.

The MYC-YA157C CPU Module is priced at $29 and the MYD-YA157C Development Board is $65.
