RAK3172 is a long-range, low-power transceiver module for LoRa and LoRaWAN applications based on the STM32WLE5CC chip. Its firmware is based on RAKwireless Unified Interface V3 (RUI3), which allows you to build various functions through RUI APIs. It provides an easy-to-use, small, and low-power solution for long-range wireless data applications. This module complies with LoRaWAN 1.0.3 Class A, B and C specifications. It easily connects to various LoRaWAN server platforms such as TheThingsNetwork (TTN), Chirpstack, Helium, etc. It also supports LoRa point-to-point (P2P) communication mode, which helps you quickly implement your own custom long-distance LoRa network.
