In the BOM, the endstop R1 is 180ohms… Any reason why 150ohms won’t work here? I’m testing 150 in a breadboard and things seem to work fine.
(reason being is that I will have 150ohm SMDs and just too lazy to make a special order for 180ohm resistors)
breadboard-tested, 150 works, as does 200, will likely go with the latter.
As long as above 100 Ohm you will surely stay within the maximum operating current.
However in the current design I would definetly leave out the LED it will probably mess up your output signal.
