Me and my son are doing a project that using Raspberry Pi 3 mode b+ GPIO to control led.
Now our RP3 hooked with Brickpi 3 board(we bought it few month ago, which should be the latest version). And i know Brickpi 3 use some of RP GPIOs for motor/sensor control. We just need to find out which gpio Brickpi 3 not using so we can take them over. I searched around in your forum and fund some schematic, but it seems quite out of date and only present few of them which used by motor control.
Can you please give us more info about this so we can move on?
Thank you very much,
