SparkFun SAMD21 Pro RF Hookup Guide
The SparkFun SAMD21 Pro RF is the fated meeting of a SAMD21 and a long-range RFM95W LoRa®-enabled radio. The outcome is a compact, blazing fast microcontroller with excellent point to point data transmission in the 915MHz ISM radio band with LoRa capabilities. In this tutorial we'll break down the capabilities of the development board, give you a brief introduction to LoRa and get you familiarized with the two Arduino libraries that will get you started with the radio and LoRaWan. If you're familiar with LoRaWan then skip ahead to the Hardware Overview, otherwise let's get started with a brief introduction to LoRaWAN.
Revision Update: In the latest revision of the SAMD21 Pro RF, we have made a few changes to improve the board, listed below. If users are unsure about which version they purchased, please refer to the pictures of the updated changes, shown below.
