I created a custom LoRaWAN Arduino compatible board here.
I am considering using this board to design a more complete dev board for others. The core design of the board is actually using Adafruit's design. Ideally, I would like to supply my own BSP that leverages the Adafruit BSP. I've seen examples of this on SparkFun with their various dev boards.
Is this something I would need to contact Adafruit about? Or is just part of the Arduino license agreements.
