Questions
How big is the Pico ecg PCB?
It measures 85 × 73 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pico ecg use?
164 parts, built around the 1N4148WT and 1N6857UR-1. 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 Pico ecg KiCad files?
From the prototipado/ECG_Phantom repository on GitHub, at the commit this page was made from: the board is hardware/pico_ecg.kicad_pcb and its schematic hardware/filtros.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pico ecg 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).
