MyoWare 2.0 Muscle Sensor Development Kit
The MyoWare® 2.0 Muscle Sensor Development Kit is an Arduino-compatible, all-in-one electromyography (EMG) sensor kit that provides you with all the boards from the MyoWare 2.0 ecosystem to test out different configurations for your application. Depending on your configuration, you can visualize the muscles in action with the MyoWare 2.0 LED Shield or read the analog output using an Arduino-compatible microcontroller! Simply snap on a MyoWare 2.0 Shield, add some EMG sensor pads, attach the sensor to a muscle group, and flex!
