I'm building a gateway using the RAK 831 and a raspberry pi 3B+. I'd like to use the RAK 831 converter board, but would like to also have GPIO pins available for the use of multiple additional sensors. Are these pins still available for connection and use with the RPi, RAK 831 and RAK 831 Converter Board all attached?
There are some pins can be used as GPIO pins, but they've been covered now.
