BioAmp EXG Pill – Analog front-end amplification for ECG, EMG, EOG, and EEG biosensing

BioAmp EXG Pill is a small, powerful Analog Front End (AFE) biopotential signal acquisition board that can be paired with any 5 V Micro Controller Unit (MCU) with an ADC. It is capable of recording publication-quality biopotential signals like ECG, EMG, EOG, and EEG, without the inclusion of any dedicated hardware or software filters. It’s small size allows easy integration into mobile and space-constrained projects, and it’s 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 BioAmp EXG Pill very cost-effective in comparison to other options.

What Can It Be Used For?

BioAmp EXG Pill is a one-stop solution for researchers, tinkerers, and hobbyists who are looking for novel biopotential amplification. Thus, it can be used for a wide variety of interesting biosensing projects:

• AI-assisted congestive heart failure detection using CNN (ECG)
• Heart Rate Variability calculation for heart ailment detection (ECG)
• Prosthetic arm (servo) controller (EMG)
• Palsy physical therapy quantitative analysis device (EMG)
• Real-time game controller (EOG)
• Controlling LEDs via brain waves (EEG)
• Patient monitoring device

And many more…

Versatile Design Means A Variety Of Applications

The elegant design of this board allows it to be used in 3 ways:

• Pin Header Holes allow you to solder on header pins (berg strip) for easy breadboard use
• Castellated Holes allow you to solder BioAmp EXG Pill directly onto your custom PCB to add biopotential amplification capabilities
• Electrode Holes allow you to use any 1.5 mm diameter wire as electrode cable with minimal strain
