A MyoWare 2.0 Muscle Sensor can be effortlessly connected to your Arduino microcontroller with the MyoWare® 2.0 Link Shield. A 3.5mm TRS jack on the shield allows you to connect the boards together using a 3.5mm TRS-to-TRS cable. Snap connectors on the board of the MyoWare 2.0 Link Shield make it simple to stack it on top of the MyoWare 2.0 Muscle Sensor. There are two switches on the board as well. While the other is used to choose the output mode for the raw EMG (RAW), rectified (RECT), or envelope (ENV) signal, the first is used for power. The envelope signal and power are indicated by two integrated status LEDs. Additionally, a jumper is provided for grounding or reference. MyoWare 2.0 is required.
