Review on 🏎️ Enhanced Performance TB6600 Stepper Driver Controller: Unleash Your Stepper Motor's Full Potential by Christopher Gonzalez

The device worked for a Nema 17 motor attached to a screw driver driving a syringe. I didn't need or want much power or speed, so I ran at the lowest current of 12V and 16 microsteps. Silky smooth and quiet. Drawn about 125 mA. I deducted a star due to the lack of documentation and the fact that the activation logic is such that you have to actively manage EN to stop/deactivate it. I've looked at other specimens of this and found paperwork so proceeded cautiously and found that inputs can take 9 to 42 volts. I have not attempted to drive optical devices beyond 16V by either dropping the cathode or driving the anode + to voltage. The inputs have some sort of current regulation mechanism so you don't blow them up and don't seem to need a quenching resistor. Documentation on this would be good. If it doesn't spin in the direction you want, one option is to swap out a wire wrap. I ran the Pulse + Terminal with a 555 timer board at about 800Hz at 16 microsteps, which is 800/16 steps per second, and the motor has 200 steps per revolution, which is 0.25 revolutions per second. The speed of rotation of the screw was about 3 revolutions per inch, so the movement of the syringe was about 1 inch in 12 seconds. I chose 12V because a 555 timer might work there and I had a small wall mounted transformer that output 12V at 500mA. I put together a small circuit using 3 diodes and an NPN transistor to add logic to work with two pedals. I'll add the schematic later. My freehand sketch is illegible.
