Questions
How big is the Bpm meter PCB?
It measures 60 × 44 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bpm meter use?
85 parts, built around the RP2040, AOZ1282CI, W25Q128JVSIQ and SLS0391FR1A1GD. 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 Bpm meter KiCad files?
From the schenfab/bpm_meter repository on GitHub, at the commit this page was made from: the board is hw/bpm_meter.kicad_pcb and its schematic hw/bpm_meter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bpm meter design in my own project?
Its repository states no licence, so its author keeps all rights: ask schenfab before reusing the design.
