Build and test wireless muscle-sensing projects with this Arduino-compatible electromyography (EMG) kit from the MyoWare 2 ecosystem. It centres on the MyoWare 2 Muscle Sensor, which measures muscle activity from the electric potential at the skin, commonly called surface electromyography or sEMG.
The included MyoWare 2 Wireless Shield receives readings from the muscle sensor and transmits the sensor data wirelessly using the included ESP32-WROOM. It also has a built-in LiPo battery to power the muscle sensor and ESP32 module remotely, plus snap connectors and low-profile pogo pins so it can stack neatly on top of the MyoWare 2 Muscle Sensor without soldering.
Inside the kit are 20 biomedical sensor pads, a mini screwdriver for removing shields, a USB A to C cable for charging the wireless shield or connecting a microcontroller to a computer, a sensor cable for reaching muscle groups away from the sensor, and a MyoWare cable shield.
The redesigned MyoWare 2 sensor outputs a filtered and rectified signal that represents muscle flexion, making it suitable for Arduino-compatible projects, wireless experiments, and MyoWare 2 add-ons such as the LED Shield. Documentation includes hookup guides, the MyoWare Arduino Library, ArduinoBLE reference material, and example code resources.
Features:
- Arduino-compatible: all-in-one electromyography (EMG) sensor kit for wireless MyoWare 2 projects.

Jargon buster
Plain-language definitions for the technical terms used above.
- ESP32
- ESP32 is a family of microcontroller modules with built-in wireless features such as Bluetooth and WiFi. Knowing this product uses an ESP32-based module helps explain how it provides wireless serial communication and firmware update features.
- 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.
- 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.
