Open source BioAmp measures EEG, ECG, EMG and EOG

BioAmp EXG Pill is an open source biopotential analog front-end (AFE) module from Upside Down Labs. Based on TL074 quad low-noise JFET-input operational amplifier, the EXG Pill works as a single channel biopotential amplifier that can amplify low magnitude electrical signals produced by our body. The EXG in the name is a placeholder. Replace the “X”, and you get EEG, ECG, EMG and EOG. And yes, the EXG Pill can measure all these signals if you configure it appropriately and use the right firmware. BioAmp EXG Pill can be interfaced to any 5V microcontrollers. The analog output from the module can be sampled by internal ADCs of microcontrollers or external ones.

The project is completely open source, allowing you to get a copy of all the source files, and modify and redistribute them as you wish. BioAmp EXG Pill v1.0 will be soon launched at Crowd Supply. If you want to get your hands on one, be quick to subscribe to the project page at Crowd Supply. Once the project is active, you can pre-order the modules.
