MyoWare 2.0 LED Shield

The MyoWare 2.0 LED Shield is designed to display the magnitude of a target muscle’s signal and power the MyoWare 2.0 Muscle Sensor with its built-in battery. The blue 10-segment bar graph shows the magnitude of the measured signal. The more muscle activation measured, the higher up the board LEDs will go!

With this shield, you will be provided with a visual representation of the signals provided by the MyoWare 2.0 Muscle Sensor. The LED shield is equipped with snap connectors on the board so you can easily stack it on the top side of the MyoWare 2.0 Muscle Sensor and 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) battery soldered to the board. Recharge the battery through the USB Type C connector and its dedicated LiPo charging circuit is set to a charge rate of 40mA. This board also includes status LEDs for charging (CHG, FULL, and power (VIN). 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 gauge how hard youre working a muscle during a workout, as a teaching tool, or add some myoelectric flair to your Halloween costume!
