The MyoWare® 2.0 Muscle Sensor Wireless Kit is an Arduino-compatible, all-in-one electromyography (EMG) sensor kit that provides you with all you need from the MyoWare 2.0 ecosystem to test out wireless configurations for your application. The MyoWare® 2.0 Wireless Shield is designed to take in readings from the MyoWare 2.0 Muscle Sensor and wirelessly transmit sensor data with the included ESP32-WROOM! This shield also includes a built-in LiPo battery to power the muscle sensor and the ESP32 module remotely. The Wireless Shield is equipped with snap connectors and low-profile pogo pins on the board, so you can easily stack it on the top side of the MyoWare 2.0 Muscle Sensor. Simply select a Power Source and flip the power switch to the ON position to give the sensor all the power it needs to work its myoelectric magic.

The kit also includes 20 biomedical sensor pads, a mini screwdriver to easily remove shields, a USB A to C cable to recharge the wireless shield or connect your microcontroller to a computer, a sensor cable to connect to muscle groups away from the sensor, and a Myoware cable shield.

The MyoWare 2.0 Muscle Sensor included in this kit has been redesigned from the ground up with a new, easy-to-use, compact design and upgraded with the latest and greatest chipset, improving sensor performance and reliability. The sensor measures muscle activity through the electric potential of the muscle, commonly referred to as surface electromyography (EMG or sEMG for short). When your brain tells your muscle to flex, it sends an electrical signal to your muscle to start recruiting motor units (the bundles of muscle fibers that generate the force behind your muscles).

The harder you flex, the more motor units are recruited to generate greater muscle force. The greater the number of motor units, the more the electrical activity of your muscle increases. MyoWare 2.0 Muscle Sensor will analyze a muscle's filtered and rectified electrical activity and output a signal (0-VIN volts, where VIN signifies the voltage of the power source) that represents how hard the muscle is being flexed. The innovative connector system eliminates the need to solder connections for the MyoWare 2.0 ecosystem, whether visualizing the muscles in action with the MyoWare 2.0 LED Shield or reading the analog output with an Arduino-compatible development board.

Important: Boards in the MyoWare 2.0 ecosystem are not intended to diagnose disease or other conditions or cure, mitigate, treat, or prevent disease in humans or other animals.

The MyoWare 2.0 ecosystem consists of shields that easily interface with the MyoWare® 2.0 Muscle Sensor, which is a low-cost, Arduino-compatible, all-in-one electromyography (EMG) sensor from Advancer Technologies. The innovative connector system allows users to easily snap shields together with a compact low profile and connect to a microcontroller's analog input to measure raw, filtered, and rectified electrical activity of a target muscle. This eliminates the need to solder connections between boards.

This product is a collaboration with Brian Kaminski from Advancer Technologies. A portion of each sales goes back to them for product support and continued development.
