MyoWare 2.0 Power Shield

The MyoWare® 2.0 Power Shield is designed to seamlessly power the MyoWare 2.0 Muscle Sensor for remote applications. Equipped with snap connectors, it easily stacks on top of the Muscle Sensor. Simply flip the switch to the ON position to supply the sensor with the power it needs to perform its myoelectric magic.

This board includes a 40mAh single-cell lithium polymer (LiPo) battery, rechargeable via a USB Type C connector. The dedicated LiPo charging circuit is set to a charge rate of 40mA. Status LEDs indicate charging (CHG), full charge (FULL), power (VIN), and envelope (ENV). Using battery power for the MyoWare 2.0 Muscle Sensor ensures a cleaner signal and eliminates the risk of creating a dangerous current path to the power grid, making it ideal for portable applications.

Note: Due to the battery installed, this item may take longer to process and does not qualify for same-day shipping. Batteries cannot be shipped via Ground or Economy methods to Alaska or Hawaii. Apologies for any inconvenience.

MyoWare and the Power Shield are not intended for use in diagnosing or treating diseases or conditions in humans or animals.
