Description of MyoWare Power Shield:

MyoWare Power Shield is designed to use two standard CR2032 coin cell batteries to power the MyoWare muscle sensor. These will be connected in parallel for extended capacity at a nominal 3.0V.

Connecting the MyoWare muscle sensor to battery power allows for a cleaner signal while eliminating the possibility of creating a dangerous current path to the mains.

One thing to note is that due to the size of the batteries, you cannot run the remote cable header on the MyoWare Muscle Sensor. If you need to access these connections, this Power Shield will need to be stacked on top of the boards that need access.

The MyoWare muscle sensor, to which this shield attaches, is an all-in-one Arduino-powered electromyography (EMG) sensor from Advancer Technologies. The MyoWare board acts by measuring the filtered and rectified electrical activity of a muscle; outputting 0-Vs Volts depending on the amount of activity in the selected muscle, where Vs stands for the voltage of the power source.

Note: The MyoWare Power Shield and MyoWare LED Shield provide power, but at slightly different voltages. Do not use both shields at the same time.
