Hi,
I'm building my OptoEndstops V2.1 with an alternate 4-pin opto switch (TCST 2103).
Some ideas for less frustration:
- Cutting the trace marked "A" and brige it to "B"
When supporting multiple opto switches, why not bridge it like the Half/Full switch on the stepper motor driver?

This would require to bridge it for H21LOB too, but it's like 5 seconds of work to solder.
- making the LED work on alternate opto switches.
With the modification for the 4-pin opto switch, one cut the VCC trace from the LED. There will be no use for R3 if you don't hook up the LED.
I think this should be added to the documentation at least.
