Questions
How big is the Bbqueue PCB?
It measures 33.5 × 46 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bbqueue use?
31 parts, built around the ATSAMD21E18A-AF, ADS1115IDGS, AP2112K-3.3 and MJ-2523-SMT. 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 Bbqueue KiCad files?
From the minor-industries/hardware repository on GitHub, at the commit this page was made from: the board is bbqueue/bbqueue.kicad_pcb and its schematic archive/led-driver-breakout/led-driver-breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bbqueue design in my own project?
Its repository states no licence, so its author keeps all rights: ask minor-industries before reusing the design.
