Questions
How big is the Avr910 PCB?
It measures 85.7 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Avr910 use?
20 parts, built around the ATTINY2313A-PU. 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 Avr910 KiCad files?
From the makeo/AVR910-Prog repository on GitHub, at the commit this page was made from: the board is pcb/avr910.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Avr910 design in my own project?
Its repository states no licence, so its author keeps all rights: ask makeo before reusing the design.
