A compact LoRa transceiver mini shield built around the Semtech SX1276, designed to attach to Thing Plus format development boards. The RFM97C operates at 100 mW output power and is suited for long-range, low-power, low-data-rate communication (up to hundreds of metres at ~500 bps).

The board includes a PTH solder point for a wire antenna (~3" for 915 MHz) with a stress relief hole, plus a U.FL connector for attaching an external RP-SMA LoRa antenna when greater range is needed.
