Hello! I’m attempting to rig a (hopefully) simple manipulator using a car door lock actuator (small geared dc motor). They’re super cheap and plentiful, so I won’t be too heart broken if it doesn’t last long underwater. I know my 2.8 has a 9V PWM channel available, but can it be used di-directionally? If not, I could use that PWM channel to power a potted brushed ESC, and then one of the servo channels to control it. I’d be wasting an output, but the plus would be that I could program it to cut power to the manipulator if its current draw exceeded 2A. I believe that pin A0 measures non-ESC current, correct?
Alternately, is there a way that I could wire the brushed ESC inside the e-tube so that its output could be routed through the existing aux wires easily? Thank you in advance for your ideas!
