Product description: MyoWare 2.0 Power Shield - power shield - SparkFun DEV-18427
MyoWare 2.0 Power Shield is a power shield for modules from the MyoWare 2.0 series. It is equipped with a 3.7 V lithium-ion battery with a capacity of 40 mAh , snap-on connectors, a power switch and a USB type C connector. Thanks to the battery, you can create a mobile device measuring muscle activity in conjunction with the EMG muscle sensor , which can be easily connected with a cover by means of snap connectors . The battery can be charged directly via the USB Type-C port with a current of 40 mA. On the board you can also find status LEDs informing about battery charging (CHG, FULL and power supply - VIN).
MyoWare 2.0 and Cable Shield are not intended to diagnose, cure, alleviate or prevent disease or other conditions in humans or other animals.
MyoWare 2.0 ecosystem
The MyoWare 2.0 ecosystem created by Advancer Technologies consists of overlays and sensors equipped with snap-on connectors that allow them to be easily connected with each other, which together with Arduino form a universal tool for studying muscle activity - electromyography (EMG). The innovative system of snap-on connectors allows easy connection of modules, and the analog 3.5 mm TRS jack connector is used to connect to the microcontroller by which the raw, filtered and rectified electrical activity of the target muscle is measured. This eliminates the need to solder the joints between the boards.
The manufacturer has prepared a detailed user guide for the MyoWare 2.0 ecosystem.
