SparkFun SAMD21 + LoRa 868/915MHZ - Qwiic

The SparkFun Pro RF is a LoRa®-enabled wireless board that marries a SAMD21 and a long-range RFM95W to make a compact and easy-to-use IoT Arduino board. With its fast MCU and excellent point to point data transmission in the 915MHz ISM band with LoRa Capabilities, the Pro RF is a great choice for anyone interested or experienced in utilizing long range data communication.

Every pin on the SparkFun Pro RF is accompanied with a ground connection making the buttons and LEDs easy to connect. In case you're building something to be embedded into clothing or other physically harsh environment the antenna includes a stress relief hole to make sure your wire antenna survives. A short wire antenna is sufficient for "short" distances, but SparkFun have also included a u.FL antennae connector for potentially longer distances.

The Pro RF also includes a power switch and 2-pin JST connector for powering from a lithium battery. With a Micro-B USB and the power switch in the off position, the Pro RF will charge the attached battery! The board programs over a reinforced Micro-B connector with a slim reset button that fits nicely on the side of the board. SparkFun have also added their popular Qwiic connector to the edge of the board making it incredibly easy to add sensors and actuators without the need for solder or a soldering iron!
