Questions
How big is the ECG Blood Pressure Final PCB?
It measures 114 × 99 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ECG Blood Pressure Final use?
83 parts, built around the MPX5050GP, MCP3202-CI/P and IRFD120. 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 ECG Blood Pressure Final KiCad files?
From the Xeretis/SPRO2Hardware repository on GitHub, at the commit this page was made from: the board is ECG_Blood_Pressure_Final.kicad_pcb and its schematic ECG_Blood_Pressure_Final.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ECG Blood Pressure Final design in my own project?
Its repository states no licence, so its author keeps all rights: ask Xeretis before reusing the design.
