{"product_id":"myoware-2-0-wireless-shield","title":"MyoWare 2.0 Wireless Shield","description":"\u003cp\u003eThe MyoWare® 2.0 Wireless Shield is designed to take in readings from the \u003ca href=\"\/products\/myoware-2-0-muscle-sensor\"\u003eMyoWare 2.0 Muscle Sensor\u003c\/a\u003e and wirelessly transmit sensor data with the ESP32-WROOM! This shield also includes a built-in LiPo battery to remotely power the muscle sensor and the ESP32 module. 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.\u003c\/p\u003e\n\u003cp\u003eThe board's \u003ca href=\"\/products\/usb-a-to-usb-c-cable-1m\"\u003eUSB type C\u003c\/a\u003e and CH340 USB-to-serial converter enable programming via serial using the Arduino IDE. As you might expect, a reset button resets the ESP32. Various protection circuits are built into the board: ESD protection diodes for the USB data lines, a resettable PTC fuse for VUSB, and ideal diodes for protection on the VUSB and VBATT nets.\u003c\/p\u003e\n\u003cp\u003eEach board comes with a 40mAh single-cell lithium polymer (LiPo) battery connected to it. The battery can be recharged through the USB Type C connector, and its dedicated LiPo charging circuit is set to a charge rate of about 40mA. Operating your MyoWare 2.0 Muscle Sensor on battery power and transmitting data wirelessly allows for complete isolation from the power grid.\u003c\/p\u003e\n\u003cp\u003ePower is regulated down to 3.3V. Users can select their power source as well as turn on\/off the board with included switches. A button to manually place the ESP32 in bootloader mode is populated as well. This button can also be used as a general-purpose button as well. The board is equipped with two horizontal \u003ca href=\"\/search?q=qwiic+cable\u0026amp;narrow_by=\u0026amp;sort_by=relevency\u0026amp;page=1\"\u003eQwiic connectors\u003c\/a\u003e and 2.2kΩ pull-up resistors if you decide to include additional Qwiic-enabled devices. Standard 0.1\"-spaced plated through holes (PTHs) break out a few of the ESP32 module's pins on the edge of the board for users.\u003c\/p\u003e\n\u003cp\u003eThis board also includes status LEDs for power (PWR), charge status (CHG), user LED (13), and envelope (ENV). There are additional jumpers for power (PWR), USB shield (SHLD), reference (REF), raw EMG (RAW), envelope (ENV), and I2C pull-up resistors (I2C).
