Questions
How big is the MegaProgrammer PCB?
It measures 89 × 93 mm and has 4 copper layers, 1.6 mm thick.
What parts does the MegaProgrammer use?
35 parts, built around the ATMEGA2560-16AU, FT232RNL-REEL, CC0805KRX7R9BB104 and CC0805JRNPO9BN470. 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 MegaProgrammer KiCad files?
From the clydeshaffer/gametank repository on GitHub, at the commit this page was made from: the board is Hardware/KiCad/tools/cartflasher/MegaProgrammer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MegaProgrammer design in my own project?
Its repository states no licence, so its author keeps all rights: ask clydeshaffer before reusing the design.
