Questions
How big is the Handheld PCB?
It measures 167.5 × 79 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Handheld use?
356 parts, built around the ESP32-S3-MINI-1-N8, TLV62585PDRL, DRV8837CDSG and GT-TF003-H0185-02. 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 Handheld KiCad files?
From the gamebub/gamebub-pcb repository on GitHub, at the commit this page was made from: the board is handheld_rev4_1/handheld.kicad_pcb and its schematic dock_rev4_1/dock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Handheld design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
