Control a project with muscle activity instead of buttons, levers or joysticks. The MyoWare® 2.0 Muscle Sensor is an all-in-one surface electromyography (sEMG) sensor that detects the electrical signals generated when a muscle flexes, then outputs an analogue signal representing the strength of that flex.
Designed by Advancer Technologies, this compact wearable board uses a solderless snap-connector system for the MyoWare 2.0 ecosystem. You can attach biomedical sensor pads directly to the sensor, helping reduce cable clutter and external signal noise, and stack compatible shields such as Power, LED and Link shields onto the low-profile connectors.
It is suited to Arduino and other microcontroller projects such as robotic prosthetics, custom game controllers and biomechanics experiments. Built-in LEDs provide quick power and signal activity feedback, while reverse polarity protected power pins help during rapid prototyping.
Features:
- Plug-and-Play Shields: Easily stack functional add-ons—like the Power, LED, and Link shields—directly onto the sensor's low-profile connectors in seconds.
- Say Goodbye to Messy Cables: The wearable board design lets you attach biomedical sensor pads directly to the sensor itself, eliminating tangled wires and reducing external signal noise.
- Broad Compatibility: Operates on a single-supply voltage of +3.3V to +5V, making it highly compatible with Arduino and other popular microcontrollers.
- Visual Feedback: Built-in indicator LEDs let you instantly monitor power status and signal activity, making troubleshooting a breeze.
- Safe and Protected: Designed with reverse polarity protected power pins to keep your board safe during rapid prototyping.

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.
- 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.
- reverse polarity protection
- A circuit feature that helps protect the board if power is connected the wrong way around. It matters because it can reduce the chance of damaging the breakout during wiring mistakes, especially in classroom or prototyping use.
