2.0 Muscle Sensor-Compatible with Arduino- All-in-one electromyography (EMG) sensor from Advancer Technologies -Measure muscle activity by detecting its electric potential-Keyed Snap Connector

It just did not work. I returned it hoping that the second one would work. But the second one did not work either. I tried and tried. Looked at videos, followed both quick and detailed instructions. Bought pads. Thinking it may be my USB from the computer, I bought a USB isolator. Still nothing. Connected it to the battery only, thinking that somehow the USB or my Arduino was screwing it up. All By itself, id not work.. I left a message with the manufacturer in the hope that they have a solution... but no reply yet. I give up and will try to return this one as well.

This new model works just as well as the previous model. I can say the sensitivity seems better and the shape is an improvement. The sensor is accurate enough you could use it as an input device like a virtual computer mouse using muscle movements.

The product never worked,i bought it with the lipo board also,the v2 r1 never worked so they gave refunds to everyone who bought it due to manufacture error,i went to sparkfun/myoware directly for help and they blocked my account and banned me from the help server after i tried everything they told me to fix it more, i promise you THIS PRODUCT DO NOT WORK! i bought 3 of them (2.01) and none of them worked after hours of trying please just by the version 1 if you can get it still or try a different brand im ashamed after dishing out over 180.00 dollars in sensors this is how the company treats people and makes inferior products

This module and related ones do not work. We imported it from the USA to Ecuador and it is a disappointment because it makes a lot of noise. It does not work with insulators or batteries. I do not recommend for any application.Este módulo y los relacionados no funcionan. Lo importamos desde USA a Ecuador y es una decepción por que tiene mucho ruido. no funciona ni con aisladores ni con baterías. No recomiendo para ninguna aplicación.

el producto llego pero no llega a funcionar ninguno realize la compra de 3 sensores

So easy to use with just the battery pack, and the led battery pack is a game changer 😲

Worked great right out of the box!
