Questions
How big is the PiBackpack PCB?
It measures 53.2 × 35.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PiBackpack use?
55 parts, built around the MSP430G2433IPW28, LM358 and P82B715D. 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 PiBackpack KiCad files?
From the UCLA-CUB/PiBackpackBoard repository on GitHub, at the commit this page was made from: the board is PiBackpack.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PiBackpack design in my own project?
Its repository states no licence, so its author keeps all rights: ask UCLA-CUB before reusing the design.
