pre order

MYO v1.4 is a ready for use compact myoelectric sensor, designed for registration and measurement muscle and heart activity.

Very easy to use with such microcontrollers as Arduino, STM32 and Teensy. To receive a signal, it is enough to power the device with a voltage of 5V (no more than 5.5V) and connect the output signal to a ADC.

We provide free libraries for using MYO v1.4 with Arduino. Also we provide sketches and software for signal visualisation by Python and Matlab.
