RAK3172 - WisDuo LoRa® module for long range wireless data

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 a maximum output power of 22 dBm. As a receiver, it can achieve a sensitivity of -148 dBm.

The module complies with Class A, Class B and Class C 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.
