Questions
How big is the Beetledouble PCB?
It measures 32 × 58 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Beetledouble use?
69 parts, built around the ATTINY1614-SSN, NCP81155MNTX, 78L12G-AB3-R and HT7550-2. 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 Beetledouble KiCad files?
From the goktugh/robotbits repository on GitHub, at the commit this page was made from: the board is beetledouble/hardware/beetledouble/beetledouble.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Beetledouble design in my own project?
Its repository states no licence, so its author keeps all rights: ask goktugh before reusing the design.
