MyoWare Muscle Sensor Single supply - MyoWare won't need +/- voltage power supplies unlike our previous sensor Embedded electrode connector - electrodes now snap directly to MyoWare, getting rid of those pesky cables and making the MyoWare wearable Raw EMG output - a popular request from grad students, the MyoWare now has a secondary output of the raw EMG waveform Polarity protected power pins - our 1 customer request was to add some protection LEd indicators - we've added two on-board LEDs one to let you know when the MyoWare's power is on
