Walter is a small-form-factor IoT system-on-module (SoM) that combines a powerful ESP32-S3 system-on-chip (SoC) with a second-generation Sequans GM02SP LTE-M/NB-IoT 5G modem and GNSS receiver. Its ESP32-S3 provides many built-in peripherals as well, including UART, SPI, I²C, CAN, Wi-Fi b/g/n, and Bluetooth 5. Walter is the only module that packs all of these connectivity options into such a small package.

Let us welcome Walter, an ESP32-S3 board with LTE-M, NB-IoT and GNSS. Walter is going to be produced in Europe and the module will be pre-certified to make your IoT end-product development easier. Walter will be highlighted in hall 3 booth 539 during embedded world 2023 where the DPTechnics team will be on hand to demonstrate Walter’s power.
