The WisBlock RAK3372 RUI3 EU868 LoRaWAN Core Module provides a practical platform for battery-powered sensors, remote monitoring and custom LoRaWAN devices.
Built around the STM32WLE5CC microcontroller with integrated LoRa radio, it combines processing and long-range wireless communication in a compact WisBlock Core.
Its supplied RUI3 firmware offers two development routes: create a standalone device using RUI3 APIs, or control it from another microcontroller using AT commands over UART. Custom RUI3 applications can be developed using Arduino IDE.
Add compatible WisBlock sensors and interfaces through a WisBlock Base Board, with battery and solar power options available through suitable base boards.
This listing is for the EU868 version. A LoRa PCB antenna with MHF-1 connector is included.
