RAKwireless RAK3172 (EU868, without IPEX)

The RAK3172 module integrates the STM32WLE5CC MCU and is a low-power, long-range, easy-to-use, compact LoRa transceiver module for wireless data applications. The module complies with the LoRaWAN 1.0.3 protocol and supports Class A, Class B, and Class C operating modes, enabling easy integration with various LoRaWAN server platforms such as TTN, Chirpstack, Actility, Tencent Cloud, and more. The module also supports LoRa P2P (peer-to-peer) communication, allowing users to quickly build their own long-range LoRa networks. Users can configure operating modes and control the module via AT commands over the UART interface. The RAK3172 is particularly well-suited for applications requiring low power consumption and battery-powered operation.
