描述 Description

RAK3172 is a low-power long-range transceiver module based on the STM32WLE5CC chip. It provides an easyto-

use, small-size, low-power solution for long-range wireless data applications. This module complies with Class

A, B, & C of the LoRaWAN 1.0.3 specifications. It can easily connect to different LoRaWAN server platforms like

TheThingsNetwork (TTN), Chirpstack, Actility, etc. It also supports LoRa Point-to-Point (P2P) communication

mode, which helps you implement your own customized long-range LoRa network quickly.

You can configure the mode and operation of the module using AT commands via a UART interface. RAK3172

also offers low-power features, which are very suitable for battery-powered applications.
