Questions
How big is the Programmer PCB?
It measures 10.5 × 14.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Programmer use?
13 parts, built around the FT230XS-R. 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 adaand00/heptachron repository on GitHub, at the commit this page was made from: the board is PCB/Programmer/Programmer.kicad_pcb and its schematic PCB/Heptachron/7-Segment-Cree-PLCC2.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 publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
