Coming soon · Crowd Supply campaign
HealthyPi Move Ultralight
A screenless, open-source wrist wearable. PPG, SpO₂, HRV, sleep, stress, respiratory rate, skin temperature, daily activity — 10+ days on a charge, with on-device baselines that learn what normal looks like for you.
Crowd Supply will email you when the campaign goes live, with early-bird pricing.

What it does
Screenless by design
Every milliamp goes into sensor accuracy and battery life — not pixels. Insights surface through a companion app, haptic feedback, and LED indicators.
10+ days per charge
300 mAh Li-Po with USB-C and magnetic pogo-dock charging. Typical wear time exceeds a week between charges.
Adaptive baselines, on-device
PPG, SpO₂, HRV, sleep staging, stress, respiratory rate, skin temperature, daily activity. 30 days of self-calibration learn your normal so alerts mean something.
Open hardware, open firmware
NDA-free AS7058 PPG AFE — no black boxes. Apache 2.0 firmware for both SoCs (STM32U595 + nRF54L15), drivers, and signal-processing pipelines.
Built on open hardware — no black boxes
Move Ultralight uses the AS7058 PPG analog front-end specifically because it ships without an NDA — meaning the entire signal chain, from raw photodiode reads through the on-device algorithms, can be published. Firmware for both SoCs (STM32U595 and nRF54L15, on Zephyr RTOS), drivers, register configurations, and signal-processing pipelines are Apache 2.0.
Hardware schematics and KiCad sources go up the day the campaign launches. You can read what the device sees, fork the firmware, swap algorithms, or build on top — same promise as every ProtoCentral product.
