The RAK3172 LoRa Module includes a STM32WLE5CC chip, which supports eight (8) spreading factors (SF5 ~ SF12) and signal bandwidth that can be adjusted between 7.8 kHz to 500 kHz. It has Ultra-Low Power Consumption of 1.69 μA in sleep mode, but during the Transmit Mode, it can reach the maximum output power of 22 dBm. As a receiver, it can achieve a sensitivity of -148 dBm.
The module complies with Class A, ClassB, Class C of LoRaWAN 1.0.3 specifications, and it also supports LoRa Point to Point (P2P) communications. The module is suitable for various applications that require long-range data acquisition and low power consumption, 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. Also, it offers low-power features that are very suitable for battery-powered applications.
