RFM95W LoRa Wireless Module 915Mhz

The RFM95W wireless module is built around Semtech’s SX1276 transceiver featuring the LoRa™ long range modem that provides ultra-long range spread spectrum communication and high interference immunity. We used these in our Mini Ultra Pro board to achieve long range transmission distance. Besides operating in the LoRa™ mode, the module is also capable of running in FSK, GFSK, MSK, GMSK, and OOK mode.
