The endstop support board comes complete and assembled (without the printed parts).
It is a microswitch endstop board for X and Y axes with Omron D2FS-FL-N switches and 4-pin Molex SL connector.
The Microswitch XY Endstop board Voron facilitates the wiring of XY end switches for the printer Voron.
The PCB comes fully assembled (or PCB and parts) with.
2 Omron D2FS-FL-N end switches
1 4-pin connector (Molex SL).
The 4-wire harness is also compatible with the Hall effect board.
The VIN pin is not used.
If you are not going to switch to the Hall effect board, you can run 3 wires instead of 4 since they share a common GND ground.
This board is based on the VoronHardware team's project, published on GitHub:
