More info about this project in Voltlog #368. If you would like to order one of these boards ready assembled, check out my Tindie store.
It measures 56.9 × 63.9 mm and has 2 copper layers, 1.6 mm thick.
53 parts, built around the LM2576-5.0WU, USBLC6-2SC6, LM1117-3.3 and CESD3V3D5. 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 eddyem/ARMsingleboard repository on GitHub, at the commit this page was made from: the board is OrangePiZero2_expboard/opi-hat.kicad_pcb and its schematic OrangePiZero2_expboard/opi-hat.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
