Here you will find one or more sample PlatformIO embedded projects designed to transmit LoRaWAN packets using a RAKwireless WisBlock Starter Kit. The starter kit is just that, a base developer board that can have multiple combinations of expansion boards added to it. The full WisBlock offering can be seen here.
