Questions
How big is the Fg programmer PCB?
It measures 51 × 21.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Fg programmer use?
19 parts, built around the CP2104EK, MMBT3904-TP and SP0503BAHTG. 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 Fg programmer KiCad files?
From the plantalytix/hardware repository on GitHub, at the commit this page was made from: the board is plantalyitx-programmer/fg_programmer.kicad_pcb and its schematic plantalyitx-programmer/fg_programmer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fg programmer design in my own project?
Its repository states no licence, so its author keeps all rights: ask plantalytix before reusing the design.
