Does anybody use the Archim board? What is the PWR EXP plug in go to?
I am not seeing that on the board. Do you have a picture?
You only need power B&C and Motors XYZ
Based on what I can gather from the schematic it is probably a power “expansion” source. If you have some sort of accessory you need to power, you could source it here.
5V and Gnd are self explanatory. Vmot should equal the voltage supplied to C+.
I don’t see any indication of how much current they can safely source, though.
So if I had a small laser pointer, I could run it off that maybe? I would be using the laser pointer to help along my material with the starting point.
You need a PWM pin, I should have one listed on the laser page. There are not many free.
