Description

This is a revised Pin27 Board, which breaks out Pin 27 for a BLTouch/other Sensor, and adds a Schmitd trigger to help fix the rotary encoder. I have also added PCB Standoff holes, so you can buy/print 11mm standoffs to support the overhanging edge.

Ideally this would completly fix the extra noise and inputs that are detected while turning the encoder, but it doesnt. It helps a fair bit though.
