GPIO input voltage level

What's the GPIO input voltage level on the Rick board inside Marty? I have an original Marty with v1.0.0

If the I/O is 3.3V then it looks like some extra components are needed if you use the nearby 5V power pin? Mine actually measures 5.2V

How does the microswitch work which came with Marty, the one designed for the foot?

Hello,

The logic is 5v tolerant, so it's fine to put 5v on the inputs there. The microswitch is just works very simply by switching 5v onto the input line

All the best,

Sandy
