Using 3.5mm TRS-to-TRS audio cables, the MyoWare® 2.0 Arduino Shield can effortlessly connect up to six MyoWare 2.0 Muscle Sensors and Link Shields. To read up to six muscle groups, simply stack the board on your Arduino and connect the sensors. The board is already pre-populated with male headers. Development boards with the Arduino Uno R3 standard footprint can be directly paired with the Arduino shield form-factor. On this shield, all six of the Arduino's analog input pins (A0-A5) are set aside. A power jumper to choose between 3.3V for the muscle sensors and 5V (default) is included on the back of the Arduino shield. A TRS-to-TRS cable and a MyoWare 2.0 Link Shield are required for
