MyoWare 2.0 Muscle Sensor
Surface EMG sensor board that amplifies and rectifies electrical signals from muscle contractions into a single analogue output voltage. Snap-on electrode connections; output scales with muscle activation level.
Surface EMG sensor board that amplifies and rectifies electrical signals from muscle contractions into a single analogue output voltage. Snap-on electrode connections; output scales with muscle activation level.
Input Voltage (VIN), primary pin 1 in the MyoWare v2 advanced guide; powers the sensor.
Ground (GND), primary pin 2 in the MyoWare v2 advanced guide.
Envelope (ENV) output, primary pin 3; Adafruit states the sensor outputs a 0-VIN signal representing muscle flex and the guide labels this as EMG envelope output.
Rectified (RECT) output, optional pin 4 in the MyoWare v2 advanced guide.
Raw (RAW) output, optional pin 5 in the MyoWare v2 advanced guide.
Mid-muscle (MID) electrode, optional pin 6 and snap socket G in the MyoWare v2 advanced guide.
End-muscle (END) electrode, optional pin 7 and snap socket H in the MyoWare v2 advanced guide.
Reference (REF) electrode, optional pin 8; the guide also identifies reference electrode port E and snap socket F.
