Walter - WiFi/BLE/NB-IoT/LTE-M/GNSS Module

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. While ideal for prototyping you can also use Walter for production as it is fully certified (CE, UKCA, FCC, IC, RCM).

Walter comes with a range of fully open-source software libraries so you can jumpstart your 5G IoT project in minutes using your preferred languages and toolchains. It supports ESP-IDF, Arduino, MicroPython, and Toit. 

Walter is fully pin compatible with PyCom GPy and can be swapped in without redesigning carrier boards.
