Designed by ProtoCentral Electronics in India, the HealthyPi 6 is an open-source, portable, research-grade biosignal acquisition device designed for academic research, education, and prototyping. It targets labs, classrooms, and field studies that need professional-quality physiological measurements without bulky desktop systems or proprietary lock-in. Building on the HealthyPi 5 (2023) and HealthyPi 4 (2019), the HealthyPi 6 is a standalone device with 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. Built around the STM32H757 real-time microcontroller and an ESP32-C6 handling Wi-Fi 6, BLE, and user-interface tasks, the device features a USB-C port, onboard flash and microSD storage, and 48+ hours of operation on a charge. Modular HealthyLink ports allow for EEG, EMG, GSR, additional analog inputs, triggers, and co-processors expansion. These features make it suitable for cardiovascular and sleep research, rehabilitation studies, wearable prototyping, […]
