I’ve blown two of these boards. Anytime the motor stalls. I’ve used fast blow fuses on the motor wires, the power input, pretty much anything I can think of. I will not be buying a third. For $10 more you can get the SideStep from Probotix. They use the much larger Allegro chip. That chip is what most CNC’s controllers use unless they spring for discrete electronic boards like the geckos. I wouldn’t use this for anything serious.
In the description, it says “maximum motor drive voltage of around 35V”. Unfortunately the only affordable switching power supply I could find are 36v. Do you think it could handle it?

I will say that I bought two of these a year ago and they now collect dust after many failed attempts to get them working. I would not expect to be able to create your own hid device with these. The manuals roving networks supplies are like reading hieroglyphics. They don’t give any examples anywhere on how to setup custom descriptors. You won’t find any tutorials on using them unless you want to use the factory setting of “wireless keyboard”. I think Sparkfun should supply tutorials for products like these if they are going to sell them. But from what I’ve seen of the USB hid stuff is, people just expect you to copy and past other people’s vague interpretations of HID tables. So unless you are going to become a HID/USB guru over the course of years, find something else. these boards offer very little in simplifying anything. It’s a shame.
