The Qwiic RF is a LoRa-enabled packet radio board built around the HopeRF RFM95W module at 915 MHz. Designed for sending short sensor data packets from one Qwiic I2C bus to another — one board transmits, the other caches received messages until they are read over I2C.

Using only the included patch antenna, the board achieves up to approximately 2.5 km line-of-sight range in ideal conditions. For longer distances, a U.fl connector allows connection to an external high-gain antenna (jumper configuration required). The patch antenna can be snapped off to save space if not needed.
