What is it?

BioAmp EXG Pill is one of a kind pill-size chip that can record publication-grade biopotential signals from your body be it from the heart (ECG), brain (EEG), eyes (EOG), and muscles (EMG). It is a powerful analog-front-end (AFE) biopotential signal-acquisition board that can be paired with any microcontroller unit (MCU) or single-board computer (SBC) with an analog-to-digital converter (ADC) such as Arduino UNO & Nano, Espressif ESP32, Adafruit QtPy, STM32 Blue Pill, BeagleBone Black, and Raspberry Pi Pico, to name just a few. It also works with any dedicated ADC, like the Texas Instruments ADS1115 and ADS131M0x, among others.

What makes it different?

• Record publication-quality biopotential signals like ECG, EMG, EOG, or EEG
• Small size (25.4 x 10.0mm) allows easy integration into mobile and space-constrained projects
• Powerful noise rejection makes it usable even when the device is close to the AC mains supply
• Any 1.5 mm diameter wire can be used as a strain-relieving electrode cable, making it very cost-effective
• Pair it with any MCU with an ADC. It is by default compatible with 5V but you can make it compatible with 3.3V devices as well using a voltage divider
• Configure the gain, band pass filter and electrode count according to your requirements
