## Description

The MyoWare® 2.0 Link Shield is designed to easily connect a [MyoWare 2.0 Muscle Sensor](https://core-electronics.com.au/search/?q=18429) to your Arduino microcontroller. The shield provides a 3.5mm TRS jack so that you can use a 3.5mm TRS-to-TRS cable to link the boards together. The MyoWare 2.0 Link Shield is equipped with snap connectors on the board so you can easily stack it to the top side of the MyoWare 2.0 Muscle Sensor.

The board also includes two switches. One is used for power while the other is selecting the output mode for the raw EMG (RAW), rectified (RECT), or envelope (ENV) signal. Two status LEDs are built in for power and the envelope signal. A jumper is also included for reference or ground. You'll need the [MyoWare 2.0 Arduino Shield](https://core-electronics.com.au/search/?q=18426) and a development board with the Arduino Uno R3 footprint to link each MyoWare 2.0 Muscle Sensor and Link Shield stack.

**Note:** MyoWare and the Link Shield are not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation treatment, or prevention of disease, in a man or other animals. Additionally, this Shield does not include the 3.5mm TRS Cable. This will need to be purchased separately.

*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.*
