"BioAmp EXG Pill is a tiny little board for biosensing that works basically with your body straight off the bat and it is quite incredible and interesting."
"BioAmp EXG Pill board can record biopotential signals like ECG (electrocardiography), EMG (electromyography), EOG (electrooculography), and EEG (Electroencephalography), or in more simple terms, biosignals from the heart, muscles, eyes, or brain..."
"Think of turning on a light with your mind, or opening a door or controlling a robotic arm or drone. All that, and many more is possible by non-invasively tapping into our body’s electrical signals."
"Open-hardware BioAmp EMG Pill gets a redesign, broader sensor support, and a crowdfunding campaign for mass production."
"Congratulations to the ten projects that have been selected to... continue to the finals of the 2021 Hackaday Prize! Each of these are a different take on the Reimagine Supportive Tech Challenge..."
BioAmp EXG Pill is a small, powerful Analog Front End (AFE) biopotential signal-acquisition board that can be paired with any 5 V microcontroller unit (MCU) that has an analog-to-digital converter (ADC), such as an Arduino UNO, an Arduino Nano, or an ESP32, among others. It also works with any dedicated 5 V (input range) ADC like the Texas Instruments ADS1115 or ADS131M0x, among others.
BioAmp EXG Pill is capable of recording publication-quality biopotential signals like ECG, EMG, EOG, and EEG, without the inclusion of any dedicated hardware or software filters. Its small size allows easy integration into mobile and space-constrained projects, and its 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.
BioAmp EXG Pill is perfect for researchers, makers, and hobbyists looking for novel ways to sample biopotential data. It can be used for a wide variety of interesting biosensing projects, including:
…And many more examples.
BioAmp EXP Pill’s elegant design allows it to be used in three ways:

We are enthusiastic about open hardware and open source software! You can find our extensive, open-source, CERN- and MIT-licensed hardware and software documentation in our GitHub Repository. And, if you have questions, you can reach us using the Ask a technical question form below.
After contacting multiple PCB-fabrication and SMT-assembly houses in India, we identified likely manufacturing partners and had them produce a batch of prototype PCBs. The quality was good, and we intend to work with them for this production run. We also contacted a few manufacturers in China, and we will stay in contact with them as a possible backup option.
After testing and packaging the production batch of BioAmp EXG Pill boards, we will send them on to Crowd Supply’s fulfillment partner, Mouser Electronics, who will distribute them to backers worldwide. You can learn more about Crowd Supply’s fulfillment service under Ordering, Paying, and Shipping in their guide.
Despite the supply-chain difficulties that continue to plague the electronics industry, we see very little risk for BioAmp EXG Pill. This is due, in large part, to the fact that we have already procured what we believe to be a sufficient quantity of the primary IC upon which our design relies.
