Physical productfree

An open-source hardware project for a device that records cardiography signals — ECG, PPG, stethoscope audio and arm-cuff air pressure — with a Python GUI for live capture and notebooks for analysis. The repository includes PCB gerbers, 3D-printable enclosure files and firmware so the device can be rebuilt. It is intended for research and education, not clinical or diagnostic use.
