How to Access to Gpio pins if my raspberry ?

Post by Franckapik » Tue Oct 22, 2019 1:14 pm

Hi,
I would like to know if it's possible to connect some devices like Relay board to rpi Gpio after inserting the CNC hat? The only way is to use the i2c grove with a Relay card which accept the i2c connection?

This is not possible to connect the CNC hat via i2c grove instead of serial pins to use others pins?

The CNC Hat uses the serial pins. Its possible to use 6*2 ribbon cable to move the cnc hat to the side and then access the pins.

Or having some kind of extension board between the RPi and the Hat.
