Description Attachments

The MyoWare® 2.0 Power Shield is a unique product that is designed to power the MyoWare 2.0 Muscle Sensor for remote applications. It comes with snap connectors on the board, allowing it to be easily stacked on top of the MyoWare Muscle Sensor. It is powered by a 40mAh single cell, lithium polymer (LiPo) battery, which is soldered to the board and can be recharged through a USB Type C connector. The board also includes status LEDs for charging (CHG, FULL), power (VIN), and envelope (ENV). It is 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 Power Shield is a perfect choice for powering your sensor in portable applications. It provides a cleaner signal and eliminates the possibility of creating a dangerous current path to the power grid. The board dimensions are 53.34mm x 59.69mm.

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 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.
