Product description: MyoWare 2.0 Wireless Shield - expansion module for the MyoWare 2.0 Muscle Sensor - ESP32-WROOM - SparkFun DEV-23387
MyoWare 2.0 Wireless Shield is a module that extends the functionality of the MyoWare 2.0 Muscle Sensor by adding a wireless data transmission function. Equipped with the ESP32-WROOM module, it allows for fast and stable transmission of information about muscle activity in real time. Thanks to the built-in 40 mAh Li-Pol battery and a dedicated charging system via USB Type-C connector, the sensor can operate independently of an external power supply. The board has snap connectors and low-profile pogo pins , which allow for easy and trouble-free connection to the MyoWare 2.0 Muscle Sensor. Thanks to this, there is no need to solder components. Additionally, the system has numerous protections , such as ESD diodes on USB data lines, a PTC fuse for VUSB and protective diodes on the VUSB and VBATT lines.
The manufacturer has prepared a detailed user guide for the MyoWare 2.0 ecosystem.

Main features of the module
- Wireless data transmission : thanks to the ESP32-WROOM module, it is possible to send information about muscle activity to other devices
- Built-in 40 mAh Li-Pol battery : allows operation without the need for an external power source
- Programming via USB Type-C: Thanks to the CH340 chip, it can be easily configured via the Arduino IDE
- Easy connection : snaps and pogo pins eliminate the need for soldering
- Isolation from the power grid : increases user safety and reduces measurement interference
- Voltage regulation : the operating voltage of the module is 3.3 V, which ensures compatibility with most logic circuits
- Qwiic support : two Qwiic connectors allow easy connection of additional modules using the I2C interface
- Additional PTH pins : enable advanced expansion and adaptation of the module to specific projects
Compatibility, connection and programming
The MyoWare 2.0 Wireless Shield is compatible with the MyoWare 2.0 ecosystem , allowing you to easily expand the functionality of your muscle sensor. It can be programmed using the Arduino IDE , using the CH340 converter to connect via USB Type-C. Once the appropriate code has been uploaded, data can be sent wirelessly to devices that support ESP32 . Connecting the board is intuitive - just place it on the MyoWare 2.0 Muscle Sensor, select a power source, and turn the module on . Additional configuration jumpers give you control over features such as pull-up resistors for the I2C bus or select a reference voltage.
The MyoWare 2.0 Wireless Shield is used to read data from the MyoWare 2.0 sensor.
The module transmits data wirelessly thanks to ESP32-WROOM.
MyoWare 2.0 Ecosystem
MyoWare 2.0 is an ecosystem of overlays that can be easily connected to muscle sensors , as well as to Arduino , to create a universal electromyography (EMG) sensor. The innovative snap-in connector system allows easy connection of modules, and the analogue TRS Jack 3.5 mm is used to connect to a microcontroller, which measures the raw, filtered and rectified electrical activity of the target muscle.
