by MrSurly.

2 layer board of 0.91x1.50 inches (23.11x38.10 mm).
Shared on July 6th, 2016 04:38.

K40 Ribbon Cable to RPI-CNC adapter. Since the RPI-CNC has strong pull-ups on the limit switch inputs, this board uses transistors to invert and amplify the signal.

This board also breaks out the X-axis stepper pins.
