What is it?

BioAmp EXG Pill is one of a kind pill size chip that can record all the biopotential signals be it from your muscles (EMG), eyes (EOG), brain (EEG), or heart (ECG). 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.

Note: The BioAmp EXG Pill available at Mouser Electronics is unassembled which means that header pins and JST Ph 2.0 connector will not be soldered so you will have more ways in which you can use it

You can make projects like:

• Recording Brainwaves from Visual Cortex (EEG)
• Controlling a servo motor (EMG)
• LED Bar Graph of EMG Potential
• Chest ECG Heart Beat Detection
• Hand EKG Heart Beat Detection
• Blink Detection (EOG)
• Controlling a prosthetic hand (EMG)
• 3 Degree of Freedom Robotic Arm (EMG)
• Drowsiness Detection (EOG)
• Clicking photos by blinking your eyes (EOG)
• Heartrate activated RGB LED Controller (ECG)
• AI-assisted congestive heart failure detection using CNN (ECG).
• Heart Rate Variability calculation for heart ailments detection (ECG).
• Palsy physical therapy quantitative analysis device (EMG).
• Real-time game controller (EOG).
• Controlling LED with Brain waves (EEG).
• Patient monitoring device.

Why did we make it?

BioAmp EXG Pill has been designed to provide an affordable way to record research-grade BioPotential signals. The main aim was to make neuroscience affordable and accessible so that students and researchers can explore neuroscience by making projects on Brain Computer Interface (BCI) and Human Computer Interface (HCI).
