It runs standalone or +as a 40-pin HAT on a Raspberry Pi. + +The hardware is built around an RP2040 dual-core Cortex-M0+ main MCU with 16 MB +of flash, an ESP32-C3 wireless co-processor for BLE and Wi-Fi, a MAX30001 analog +front end for ECG and respiration, an AFE4400 front end for PPG/SpO2, a MAX30205 +temperature sensor on the Qwiic/I2C bus, a microSD slot and Li-ion battery +charging. Schematics and board layout are published as EAGLE sources under the +CERN Open Hardware Licence Version 2 - Permissive. + +This PID identifies the RP2040's USB full-speed CDC-ACM interface on the primary +USB Type-C port, which streams packetised biosignal frames to the OpenView +desktop application and to user scripts. The firmware is MIT-licensed and comes +in a Zephyr RTOS version (using Zephyr's USB device stack) and an +Arduino/Pico-SDK version; the ESP32-C3 co-processor runs a separate Zephyr +application.
