- PowerBRRR for BigTreeTech SKR 1.x/2.x:
- PowerBRRR for BigTreeTech SKR Pro/Octopus, Fysetc Spider, FLY F407, etc.:
Suggested manufacturing is using 2oz copper or gold traces.
- 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
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).
