One thing to note is that due to the size of the batteries, the remote cable header on the MyoWare Miscle Sensor can’t be passed through. If you need access to these connections, this Power Shield will need to be stacked above the board(s) that need access.
The MyoWare Muscle Sensor, that this shield attaches to, is an Arduino-powered, all-in-one 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 the amount of activity in the selected muscle, where Vs signifies the voltage of the power source.
Note: The MyoWare Power Shield and the MyoWare LED Shield both provide power, but at slightly different voltages. Don’t use both of these shields at the same time.
