@ProtoCentral HealthyPi 6 is an open-source device combining an STM32H7 MCU with an ESP32-C6 wireless module designed for academic research, education, and prototyping.

It features 3-channel/5-lead ECG, dual-wavelength PPG for heart rate and SpO₂, respiration via impedance pneumography, skin temperature sensing, and a 9-axis IMU for motion and artifact detection. Modular HealthyLink ports allow for EEG, EMG, GSR, additional analog inputs, triggers, and co-processors expansion.

Data can be visualized directly on the device or on a Windows, Linux, or macOS host running the HealthyPi Studio Desktop App.

@Ahmad_Bilal @anujdeshpandey @ZephyrIoT @ashwinkw Yes, this does have the potential, but this is currently targeted at researchers. For actual clinical use, the right approvals are required. If anybody is ready to do that, we're ready !

[ProtoCentral @ProtoCentral]

Thank you @anujdeshpandey for the mention and spreading the word !
