ESP32 + BioAmp EXG Pill

Espressif's ESP32 is a feature-rich MCU with integrated Wi-Fi and Bluetooth connectivity for a wide-range of applications. It's 12 bit ADC input is a little noisy, but it can easily be coupled with the BioAmp EXG Pill to record ECG, EMG, EOG, and EEG. Read the full update.

AdaFruit QT Py + BioAmp EXG Pill

Built around Microchip's SAMD21, Adafruit's QT Py (Cutie Pie) is indeed a cute little board. Its 12-bit ADC input is pretty good, and it can easily be coupled with BioAmp EXG Pill to record ECG, EMG, EOG, and EEG. This update includes QT Py circuit diagrams for several examples use cases. It also provides some setup advice inspired by NNNI's recent review video (thanks NNNI!) and offers a glimpse at what we'll be talking about in our next update. Read the full update.

Beyond Arduino Nano & Extending Our Campaign

Up to this point, we've been showing off the capabilities of BioAmp EXG Pill when it's used with an Arduino Nano (ATMega328P @ 16 MHz), which is enough for most projects. However, it can do even more when paired with other development boards. One of our beta testers, Rameet Singh Sachar, used a Raspberry Pi Zero and BioAmp EXG Pill to create an image-capture machine that can be controlled with the blink of an eye! This update also explains our decision, in consultation with Crowd Supply, to extend our campaign by two weeks. Read the full update.

Supportive Technology

An accurate heartbeat detection (peak detection) algorithm that works on a small microcontroller is a pretty complex task but, with our robust standard deviation-based peak detection algorithm, you can detect heartbeats very easily even on an Arduino Nano. Read the full update.

Electromyography (EMG) Walkthrough

Electromyography (EMG) is a technique for evaluating and recording the electrical activity produced by skeletal muscles. EMG is also used as a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). EMG results can reveal nerve dysfunction, muscle dysfunction, or problems with nerve-to-muscle signal transmission. This update includes examples of EMG-related projects built around BioAmp EXG Pill.
