This all-in-one MyoWare 2 electromyography (EMG) kit gives you the essentials for measuring and visualising muscle activity. It is Arduino-compatible, but the included setup is designed to follow the standalone example from the MyoWare 2 Muscle Sensor Guide, so you can use it without a microcontroller.
Snap on the MyoWare 2 LED Shield, add EMG sensor pads, attach the sensor to a muscle group and flex. The sensor measures surface EMG activity and outputs a 0-VIN volt signal, where VIN is the power source voltage, to indicate the degree of muscle flexion.
The kit includes the MyoWare 2 Muscle Sensor, MyoWare 2 LED Shield, EMG sensor pads, a mini screwdriver for removing shields, a USB-A to USB-C cable for recharging the 40mAh LiPo battery, and a MyoWare 2 Reference Cable for connecting to large muscle groups. The snap connector system allows the LED Shield to be attached without soldering, and the blue 10-segment bar graph shows muscle activation level visually.
Documentation references include the MyoWare 2 Muscle Sensor Guide, MyoWare 2 LED Shield documentation, MCP73831 datasheet, 40mAh polymer lithium ion battery information, ArduinoBLE reference material and a GitHub example repo. It suits fitness feedback experiments, teaching demonstrations and myoelectric costume or interactive projects.
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- LiPo
- A lithium polymer rechargeable battery commonly used in portable electronics projects. It matters because LiPo batteries need correct charging circuitry and care, and this board includes hardware intended for that battery type.
- MCP73831
- A lithium battery charger chip used to safely charge a single-cell LiPo battery. It matters because it lets the board recharge a battery from USB or another input without needing a separate charger module.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- 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.
- USB-C
- A modern reversible USB connector used for power and data connections. On this product it matters because it can connect directly to a computer as well as to a microcontroller project.
