Resources and Going Further
The SAMD21 Pro RF is a powerful microcontroller with LoRaWAN capabilities. To best take advantage of it, plug in a LiPo battery and a Qwiic enabled sensor. Perhaps you don't have a gateway nearby, or have found that they can be quite expensive? Look no further than our ESP32 LoRa 1 Ch Gateway with its excellent hookup guide.
