HealthyPi 6 is the latest generation of open-source biosignal acquisition device designed to bring professional-grade physiological monitoring out of traditional labs and into portable, field-ready use. Backed on Crowd Supply by ProtoCentral Electronics, this innovative platform combines multiple biosignal sensing modalities, advanced edge processing, and a user-friendly touchscreen all in one compact device.
At its core, HealthyPi 6 is built for multi-modal biosignal research. It has a combination of ECG (electrocardiography) and programmable 3-channel/5-lead, which has the capabilities of high-resolution data capture, 3-channel/5-lead PPG (photoplethysmography) heart rate and blood oxygen saturation (SpO2), respiration, temperature detecting, and motion sensors with a 9-axis IMU. These signals can be measured concurrently, and the researchers can gain a cohesive perspective of the crucial physiological functions without having to use many different devices.
One of the strongest points of HealthyPi 6 is its edge computing power. A combination of an STM32H757 dual-core and an ESP32-C6 processor running Zephyr RTOS enables real-time signal filtering, artefact detection, HRV (heart rate variability) computation, and even machine-learning-based analysis directly on the device. This means you don’t need a tethered PC or cloud connection to process your data; just use the built-in 4-inch capacitive touchscreen to view real-time waveforms and metrics on the go.
Connectivity and features:
Connection features are also very good with support of Wi-Fi 6 and Bluetooth Low Energy, as well as USB-C and onboard storage and an expandable microSD, enabling long recordings even when in remote locations. A rechargeable LiPo battery provides a long battery duration in the field research or classroom demonstration without the need to have constant power.
HealthyPi 6 is not just a single monitor, but a modular HealthyLink expansion ports that enable EEG, EMG, GSR, and other sensor modules to be dropped, and hence the platform can be extremely versatile in various research applications such as sleep research, cardiac stress testing, and neural monitoring, among others. Everything is open source, hardware, software and even firmware and allows total control to be customised by the user and the data owned by the user.
HealthyPi 6 open-source biosignal device will cost $549 on crowdfunding. It is currently available as part of an active, funded crowdfunding campaign. Orders placed now are expected to ship around May 2026, with free shipping within the United States and a modest additional charge for international shipping.
