HealthyPi 5 is the latest evolution of the HealthyPi series. It is a robust, feature-rich, open-source development board that allows you to explore many different biosignals with minimal effort. Whether you need a simple monitor for a specific vital sign or a complete health-sensor platform, HealthyPi 5 is an extensible solution to to your health-data 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 Pro-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.

With an innovative, dual-microcontroller configuration—including both a dual-core, 32-bit, Cortex-M0+ RP2040 and an ESP32 C3 RISC-V module—HealthyPi 5 is suitable for a wide range of deployments, including machine learning applications that target physiological signals. And, with both Wi-Fi and BLE connectivity, it is easy to connect your application to other devices and to the Internet.

Adaptable For Many Different Application Environments

HealthyPi 5 supports various modes of operation to help it accommodate the quirks of your particular application:

1. With our Pro-Carrier Board and display: The HealthyPi Pro Carrier Board adds safety isolation for the main USB interface, including both data lines and USB power, thanks to galvanic isolation barriers that conform to IEC 60601-1 medical safety standards. The addition of a 3.5-inch color TFT display allows you to visualize raw signals, processed data, computation progress, and analysis.
2. With our Pro-Carrier Board: Similar to the above configuration but without the display, this mode of operation can be particularly useful in applications where space is at a premium. Capable of streaming continuous data to your Linux, Mac, or Windows computer through the onboard USB Type-C port.
3. As a wireless data logger for Android and iOS devices: HealthyPi 5 can be used all by itself, in a very small enclosure, to collect data for research or for wearable applications. Both raw data and computed values can be logged using the onboard MicroSD card or streamed in realtime to the HealthyPi mobile app.
4. As a Raspberry Pi HAT: HealthyPi 5 can send instantaneous electrocardiogram (ECG), respiration, photoplethysmography (PPG), and temperature signals to an application running on the attached Raspberry Pi SBC.
