Questions
How big is the Tachometer PCB?
It measures 95 × 77 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Tachometer use?
207 parts, built around the RP2040, W25Q128JVSIQ, H11L1 and LP5907MFX-3.3. 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 Tachometer KiCad files?
From the Churrosoft/Dashdash repository on GitHub, at the commit this page was made from: the board is pcb/v2/dashdashv2/tachometer/rev2/rev2.kicad_pcb and its schematic pcb/v1/Battery-Fuel-Temperature.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tachometer design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
