HealthyPi 5 is an open-source biosignals acquisition device that combines the power of a Raspberry Pi Pico along with an ESP32C3 and provides ease-of-use of an Arduino. Whether you need a simple monitor for a specific vital sign or a complete health-sensor platform, HealthyPi 5 is an extensible solution to your health-data acquisition challenges. Out of the box, it can handle electrocardiogram (ECG), respiration, photoplethysmography (PPG), oxygen saturation (SpO₂), and body-temperature data. And it’s easy to upgrade as well! Using the Qwiic connectors on the Carrier board, you can leverage external sensor modules to capture and analyze additional biosignals, such as galvanic skin response (GSR), electroencephalogram (EEG), and electromyogram (EMG) data.

After running a successful Crowd-Supply campaign to get this off the ground, this is now available directly from ProtoCentral and also from Crowd Supply.

Features

– Pocket sized (or handheld, according to configuration), yet powerful enough for complex signal-processing and analysis tasks typically handled by devices ten times the size and cost.- Built-in storage and onboard computational power for data processing and analysis support standalone edge-computing applications.- Simplified application development thanks to software written on the solid Zephyr RTOS Ecosystem with a focus on connected, stable and secure firmware. The hardware also has support for programming with Arduino IDE and MicroPython, with ready-to-use arduino libraries for all the onboard sensors.- Pre-packaged firmware images for common applications, such as streaming data over USB, driving the Display module for usage without programming. Simple drag-and-drop interface that allows you to upload your code over USB connection.- Expandable through standard, Qwiic-compatible ports that support external sensors and modules.- Support for open-data formats, Lab Streaming Layer (LSL) compatibility for real-time synchronization, and interoperability with existing research platforms all facilitate collaboration and data sharing.- Open hardware and open-source software allow you to customize your applications without paying for expensive, proprietary client software.- Unlike previous generations of HealthyPi, our fifth edition is a complete system that can be used as a standalone device without the need for a Raspberry Pi or other host computer. This makes it ideal for remote areas and in developing countries where a host computer may not be available.
