Hello, New to the Raspberry Pi world and I have a few questions about the Grover. How many, and which, GPIO pins are available for output when a Grover is attached to a RPi 4? I will be using the Grover to hook up 8 sensors, each controlling a seperate relay that activates a solenoid. Are there at least 8 GPIO pins avaliable for output to the 8 relays? Regards, Dan

Dan,
All the pins on the Raspberry Pi GPIO board is available on the pins above the board. If you mean what GPIO pins are brought out to plugs on the Pi2Grover board, then check out the tables on the board or in the specification on shop.switchdoc.com
Hope that helps!

Re-reading the documentation, I understand how to connect sensors to the Grover, and, which GPIO pins will still be available. I'll be using all analog sensors so I'll have plenty of output pins avalable to communicate with the relays. Regards!
