Questions
How big is the Ruler PCB?
It measures 205 × 32 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ruler use?
22 parts, built around the EFM8LB12F32E-C-QFP32 and RP2040. 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 Ruler KiCad files?
From the ULAS-HiPR/pcbs repository on GitHub, at the commit this page was made from: the board is Ruler/Ruler.kicad_pcb and its schematic Mach24_CanSat/PCB_v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ruler design in my own project?
Its repository states no licence, so its author keeps all rights: ask ULAS-HiPR before reusing the design.
