SparkFun MyoWare 2.0 Cable Shield is designed to be wearable, allowing it to attach biomedical sensor pads directly to the board itself. The MyoWare 2.0 Cable Shield is used to mount the sensor pads away from the board. The shield includes a 3.5mm TRS jack where it can attach a traditional three-electrode sensor cable, allowing to test and use of the muscle sensor without actually attaching the board to a person.
