Suggested manufacturing is using 2oz copper or gold traces.
## Bill of materials
* 1x 220µF (2A) / 330µF (3A) / 470µF (4A) 63V 13x25 capacitor
* 1x WJ127-5.0-2P screw terminal
* 2x 8P 2.54mm pitch stacking headers
* 1x 2P 2.54mm pitch stacking headers
* 1x SOD123FL
## Assembly
Make sure the VM pin is cut short; you can leave GND:
Suggested stepstick and motor power connector placement:
Cover the back with kapton tape, nobody likes to get zapped accidentally ([unless it generates views you can monetize](https://www.youtube.com/channel/UCJ0-OtVpF0wOKEqT2Z1HEtA)).
# Builds
