Questions
How big is the Tregatti stable PCB?
It measures 55.9 × 121.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tregatti stable use?
147 parts, built around the ESP32-WROOM-32D, FT231XS-R, INA826AIDRGR and MAX86150EFF+. 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 Tregatti stable KiCad files?
From the tregatti-tech/ESP32ECG repository on GitHub, at the commit this page was made from: the board is KiCAD_files/tregatti-ecg/tregatti_stable.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tregatti stable design in my own project?
Its repository states no licence, so its author keeps all rights: ask tregatti-tech before reusing the design.
