HealthyPi 5 WiFi & BLE biosignal-acquisition sensor platform captures body temperature, ECG, PPG, SpO₂, and other vitals (Crowdfunding)

HealthyPi 5 is an open-source sensor platform for biosignal acquisition based on Raspberry Pi RP2040 microcontroller and ESP32-C3 WiFi & BLE module used to capture vitals such as electrocardiogram (ECG), respiration, photoplethysmography (PPG), oxygen saturation (SpO₂), and body-temperature data. It is a complete redesign of the HealthyPi v4 Raspberry Pi HAT with many of the same features. While the HealthyPi 5 also follows the Raspberry Pi HAT form factor and can be connected to a Raspberry Pi SBC to analyze the data, it can also be used as a standalone device with the processing handled by the RP2040 dual-core Cortex-M0+ microcontroller and connectivity through an ESP32-C3 wireless module, and data visualized on a 3.5-inch SPI display or a smartphone over WiFi or Bluetooth. HealthyPi 5 specifications: MCU – Raspberry Pi RP2040 dual-core Arm Cortex-M0+ microcontroller @ 133 MHz with 264 KB SRAM Wireless Module – ESP32-C3 RISC-V module with 2.4 […]

PiEEG shield for Raspberry Pi enables brain computer interfaces (Crowdfunding)

PiEEG is an open-source hardware Raspberry Pi shield that measures electroencephalography (EEG), electromyography (EMG), and electrocardiography (ECG) bio-signals and provides a brain-computer interface to applications or robots for gaming, entertainment, sports, health, etc… Ildar Rakhmatulin, a Research Associate at Heriot-Watt University in Edinburgh, is passionate about open-source brain-computer interfaces and first created the IronBCI project based on ADS1299 and STM32 and published a research paper entitled “Low-cost brain computer interface for everyday use” about his work. But cost increases related to the semiconductors shortage of recent years meant the price for his “low-cost” project shot up to over $1,000. So he went back to the drawing board and created the PiEEG shield for Raspberry Pi now available on Crowd Supply. PiEEG shield specifications: ADC – Texas Instruments ADS1299 Analog-to-Digital Converter for biopotential measurements Supported SBCs – Raspberry Pi 3 or 4, and boards with the same 40-pin GPIO header.
