Questions
How big is the Programmer PCB?
It measures 34 × 38.6 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Programmer use?
40 parts, built around the CP2102N-A02-GQFN28, AZ1084CS2-3.3TRE1, BSS816NWH6327XTSA1-HXY and CM1293A-04SO. 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 Programmer KiCad files?
From the zandmd/esp32-projects repository on GitHub, at the commit this page was made from: the board is eda/programmer/programmer.kicad_pcb and its schematic eda/disc-charger/disc-charger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Programmer design in my own project?
Its repository states no licence, so its author keeps all rights: ask zandmd before reusing the design.
