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.

Note: This item may take longer to process due to the battery installed in the equipment and therefore does not qualify for same-day shipping policy. Additionally, these batteries can not be shipped via Ground or Economy methods to Alaska or Hawaii. Sorry for any inconvenience this may cause.

MyoWare and the Power Shield are not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation treatment, or prevention of disease, in a man or other animals.

The MyoWare® 2.0 ecosystem consists of shields that easily interface with the MyoWare® 2.0 Muscle Sensor, which is a low-cost, Arduino-compatible, all-in-one electromyography (EMG) sensor from Advancer Technologies. The innovative connector system allows users to easily snap shields together with a compact low profile and connect to a microcontroller's analog input to measure raw, filtered, and rectified electrical activity of a target muscle. This eliminates the need to solder connections between boards.

This product is a collaboration with Brian Kaminski from Advancer Technologies. A portion of each sales goes back to them for product support and continued development.
