We got our Allegro A4988 stepper driver breakout PCBs back and are ready to test them. First, we verified that STEP and DIR worked (yes!) and that the LEDs lit (yes, but we need to tweak the resistors to make the brightness even). Then we tried all of the stepper-settings, you can select 1, 4, 8, or 16-microsteps. All the sleep/reset/enable pins work. Finally, we checked the current limiting functionality with a potentiometer that can be twisted to select up to 2A current per coil. This directly affects the torque, so it's easy to test by verifying that we can stall the motor with hands or vise-grips. We'll order these with 2oz copper and get them into production next!
