Legacy guide — no longer updated

HealthyPi 5 is an open-source biosignals-acquisition platform built around the dual-core RP2040 + ESP32 and three medical-grade analog front-ends: MAX30001 (ECG and bio-impedance), AFE4400 (PPG / SpO₂), and MAX30205 (temperature). It works as a Raspberry Pi HAT, as a standalone wearable, or as a desktop biosignals platform.

Download pre-built firmware

These pre-compiled .uf2 images are ready to drag-and-drop onto the device — no toolchain required. Pick the firmware that matches the display variant in your kit (or the Basic build if you have no display).

Variant Display USB stream BLE SD logging Download
Basic + ILI9488 (white display) Vitals only ✓ ✓ ✓ Download

The Basic image is the most versatile — it streams vitals over USB and BLE, logs to SD, and shows numeric vitals on the display. The Display image is purpose-built for the visual plot mode (see Display Configuration).

Flash the firmware

The HealthyPi 5 ships with the RP2040’s UF2 bootloader. Programming is drag-and-drop — no Arduino IDE or toolchain needed.
