RAK Wireless WisDuo STM32WL module without ipex

RAK3172PH

overview

The RAK3172 LoRa module contains an STM32WLE5CC chip that supports eight (8) spreading factors (SF5~SF12) and a signal bandwidth that can be adjusted between 7.8kHz and 500kHz. It has an ultra-low power consumption of 1.69μA in idle mode, but can reach a maximum output power of 22dBm in transmit mode. As a receiver, it can reach a sensitivity of -148dBm.

The module meets Class A, Class B and Class C of LoRaWAN 1.0.3 specifications and also supports LoRa Point to Point (P2P) communication. The module is suitable for various applications that require long-range and low-power data collection, such as smart meters, supply chain and logistics tracking, agricultural sensors and smart cities.

You can configure the mode and operation of the RAK3172 module using RAK3172 AT commands via a UART interface. It also provides low power consumption features, which is very suitable for battery-powered applications.
