This all-in-one electromyography (EMG) kit gives you the MyoWare 2 boards needed to experiment with different muscle-sensing setups. Depending on how you configure it, you can visualise muscle activity with the MyoWare 2 LED Shield or read an analogue output with an Arduino-compatible microcontroller.
Setup is designed to be straightforward: snap on a MyoWare 2 Shield, add EMG sensor pads, attach the sensor to a muscle group, and flex. The solderless connector system makes it easier to move between the MyoWare 2 ecosystem boards without having to wire everything permanently.
The included MyoWare 2 Muscle Sensor measures surface electromyography (EMG/sEMG) by detecting the electric potential generated when a muscle flexes. It analyses filtered and rectified muscle activity and outputs a signal from 0-VIN volts, where VIN is the voltage of the power source, to indicate the degree of muscle flexion.
The kit includes accessories for development and testing, including a mini screwdriver, USB A to C cable, MyoWare 2 Reference Cable, sensor cable, 3.5mm TRS-to-TRS cable, RedBoard Plus, and rechargeable 40mAh LiPo batteries. It is designed to follow the standalone MyoWare 2 Power Shield and LED Shield examples, as well as examples for reading a single muscle sensor with an Arduino-compatible microcontroller.
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- LiPo
- A LiPo (lithium polymer) battery is a rechargeable lithium battery widely used in portable projects because it is light and compact. LiPo cells need correct charging circuitry and careful handling to stay safe, so equipment that supports LiPo generally includes charging or protection hardware suited to that battery type.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
