The RAK3172 WisDuo Module is a low-power LoRa®/LoRaWAN® transceiver based on the STM32WLE5CC system-on-chip. This variant uses an MHF1 antenna connector, with the RF pad internally disconnected, ensuring antenna connection exclusively through the onboard MHF1 port.
 
Running RUI3 (RAK Unified Interface V3) firmware, the module supports LoRaWAN® 1.0.3 Classes A, B and C and offers flexible development through RUI3 APIs. It also supports AT and Binary command modes for use as a UART-controlled LoRa® modem.
 
This variant is optimised for EU868, RU864 and IN865 LoRaWAN® regions and is designed for compact industrial, agricultural and smart-city deployments requiring robust, long-range wireless communication.
