Questions
How big is the Tachometer PCB?
It measures 109.4 × 51 mm and has 2 copper layers, 0.3 mm thick.
What parts does the Tachometer use?
32 parts, built around the ATMEGA328P-PU, CC56-12EWA and ITR9608-F. 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 MITEngine/stirling-engine repository on GitHub, at the commit this page was made from: the board is pcb/tachometer/tachometer.kicad_pcb and its schematic pcb/tachometer/tachometer.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 states no licence, so its author keeps all rights: ask MITEngine before reusing the design.
