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.

BOM:
- 1 TE connectivity 1-84534-2 connector
- 2 3K3 0805 SMD resistors
- 2 MMBT2222A SMD transistors
- 1 1x2 0.1" pitch header [OPTIONAL]
- 1 1x4 0.1" pitch header [OPTIONAL]
- 1 0805 SMD capacitor (noise reduction) [OPTIONAL]
