RFM97C Mini Shield LoRa - 100mW
The RFM97C is a great little module that incorporates the SX1276 LoRa transceiver from Semtech. LoRa is best for long range communication (hundreds of feet), low power, and low data rates (~500bps). This 'Mini Shield' is designed to be attached to the top or bottom of any of our Thing Plus boards. Pictured is the ESP32 Thing Plus. We include a PTH soldering point for a low cost wire antenna (~3" for 915MHz) along side a stress relief hole. For folks that need a bit more oomph, there is a U.FL connector available for larger, external RP-SMA LoRa antennas.
Our example sketches make quick work of the initial setup, and the RadioLib Arduino Library makes advanced configuration and protocols (AX.25, Hellschreiber, Morse, RTTY, and SSTV) a cinch too!
Note: This revision of the PCB (x02) requires two jumpers (DIO0 and DIO1) to be closed for the best LoRa operation. So while you're soldering headers on, close those jumpers.
We do not plan to regularly produce SparkX products so get them while they’re hot!
Experimental Product: SparkX products are rapidly produced to bring you the most cutting edge technology as it becomes available. These products are tested but come with no guarantees. Live technical support is not available for SparkX products. Head on over to our forum for support or to ask a question.
