The LED Shield comes with a 40mAh single cell, lithium polymer (LiPo) battery soldered onto the board. The battery can be recharged via the USB Type C connector and its dedicated LiPo charging circuit set to a charge rate of 40mA. The board also includes status LEDs for charging (CHG, FULL) and power (VIN). By connecting the MyoWare 2.0 Muscle Sensor to battery power, you can achieve a cleaner signal and eliminate the risk of creating a dangerous current path to the power grid.
The MyoWare 2.0 LED Shield is perfect for monitoring muscle activity during a workout, as a teaching tool, or to add a unique myoelectric touch to your Halloween costume. However, please note that the MyoWare and the LED 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 humans or other animals.
The MyoWare® 2.0 ecosystem consists of shields that easily interface with the MyoWare® 2.0 Muscle Sensor, 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 sale goes back to them for product support and continued development.
