Questions
How big is the PowerCircuit PCB?
It measures 76.2 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PowerCircuit use?
63 parts, built around the DRV8833PWP, CH224K, MT3608 and TPS22929DDBV. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PowerCircuit KiCad files?
From the usandakahle/DesignProject repository on GitHub, at the commit this page was made from: the board is V3/PowerCircuit.kicad_pcb and its schematic CAD/PowerCircuits/PowerCircuit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PowerCircuit design in my own project?
Its repository states no licence, so its author keeps all rights: ask usandakahle before reusing the design.
