The WisBlock STM32WLE5 Core Module – RAK3372 is a low-power, long-range transceiver module based on the STM32WLE5CC chip. Designed for LoRa® and LoRaWAN® applications, it delivers reliable LPWAN connectivity while maintaining excellent power efficiency.
 
When plugged into a WisBlock Base Board, the RAK3372 allows you to easily add WisBlock sensor and IO modules to build scalable IoT solutions.
 
The module runs RUI3 (RAKwireless Unified Interface V3) firmware, allowing developers to create custom firmware or use it as a LoRa modem with AT and Binary commands over UART.
