|---|---|
| USB-C PD board | Negotiates input voltage from USB-C PD source |
| Motor breakout | Drives launch and spin motors |
| MCU breakout | Hosts microcontroller and Bluetooth module |
| Buck regulator | Steps down voltage for logic-level components |
Controlled via a custom React Native (Expo) app that connects over Bluetooth. The app allows users to adjust spin type, speed, and frequency from their phone—no physical controls on the machine required.

It measures 40.8 × 13.8 mm and has 2 copper layers, 1.6 mm thick.
19 parts. 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.
From the jacksterb1234/Ping_Pong_Machine repository on GitHub, at the commit this page was made from: the board is Kicad/Power_Board/Power_Board.kicad_pcb and its schematic Kicad/Kicad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask jacksterb1234 before reusing the design.
