MyoWare 2.0 Power Shield

The MyoWare® 2.0 Power Shield is designed to easily power the MyoWare 2.0 Muscle Sensor for remote applications. The MyoWare Power Shield is equipped with snap connectors on the board so you can easily stack it to the top side of the MyoWare Muscle Sensor. Flip the switch to the ON position to give the sensor all the power it needs to work its myoelectric magic.

Each board comes with a 40mAh single cell, lithium polymer (LiPo) soldered to the board. Recharge the battery through the USB Type C connector and its dedicated LiPo charging circuit set to a charge rate of 40mA. This board also includes status LEDs for charging (CHG, FULL, power (VIN), and envelope (ENV). Connecting the MyoWare 2.0 Muscle Sensor to battery power allows for a cleaner signal while also eliminating the possibility of creating a dangerous current path to the power grid. Use it to power your sensor in portable applications.
