MiniPiio SimpleIO is just that, a add-on board with simple inputs and outputs. It features 8x LED’s and 8x tactile switches. The Pi’s GPIO4/17/18/22/23/24/25/27 are each connected to an LED and switch.
You have 8x signals you can mix and match with whatever combination of LED’s or switches your design needs. So if you need more indicators you could have say 6x LED’s and 2x switch inputs and like wise, if you need more inputs than outputs you could have 5x switch inputs and 3x LED outputs.
You can find them at our store on Tindie.
Note: LED and Switches sharing the same GPIO so are not designed to used simultaneously.
