RAK3172 is a low-power long-range transceiver module for LoRa and LoRaWAN applications based on STM32WLE5CC chip. Its firmware is based on RAKwireless Unified Interface V3 (RUI3) that allows you create different functionalities using RUI APIs. It provides an easy-to-use, small-size, low-power solution for long-range wireless data applications. This module complies with Class A, B, & C of LoRaWAN 1.0.3 specifications. It can easily connect to different LoRaWAN server platforms like TheThingsNetwork (TTN), Chirpstack, Helium, etc. It also supports LoRa Point-to-Point (P2P) communication mode which helps you in implementing your own customized long-range LoRa network quickly.

It can work as a stand alone device by creating custom firmware via RUI3 APIs or can be deployed as a LoRA modem with an external host like a microcontroller or microprocessor that configures and send commands to the module using AT and Binary commands via a UART interface.

The RAK3172 is available in variants with TCXO to assure higher clock precision in low temperature conditions and with an oscillator for normal environment conditions.
