{"title":"MyoWare 2.0 Wireless Shield","handle":"myoware-2-0-wireless-shield","url":"/products/myoware-2-0-wireless-shield","description":"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 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.\n\nTThe board's USB type C 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.\n\nEach 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.\n\nPower 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 Qwiic connectors 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.\n\nThis 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). Use it as a teaching tool to reduce the number of wires in your system or add some myoelectric flair to your Halloween costume!\n\nNote: This item may take longer to process due to battery installed in the equipment and therefore does not qualify for same-day shipping policy. Additionally, these batteries can not be shipped via Ground or Economy methods to Alaska or Hawaii. Sorry for any inconvenience this may cause.\n\n\nImportant: MyoWare and the Wireless 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.\n\n\n\nThe 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.\n\nThis 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.\n\n\n\n Get Started with the MyoWare 2.0 Wireless Shield Guide\n\n\nFeatures:\n\n\nInput Voltage\n\n\n5V via USB Type C Connector\n\n\nOutput Voltage (e.g. \"VIN\")\n\n\n3.3V via  voltage regulator (RT9080)\n3.3V via Qwiic Connector\n\n\nESD Protection Diodes for USB Data Lines\nIdeal Diodes for Protection on the VBATT and VUSB Nets\nResettable PTC Fuse (Rated 6V/500mA)\nSwitches\n\n\nPower Source\nPower ON/OFF\n\n\nBuilt-in LiPo Battery\n\n\nRated Capacity: 40mAh\nNominal Voltage: 3.7V\nMax Charge Current: 1C (40mA)\n\n\nMCP73831 Single Cell LiPo Charge IC\n\n\nCharge Rate Set to ~40mA\n\n\n3.3V Voltage Regulator\nMyoWare® 2.0 Muscle Sensor Form Factor\n\n\n3x Female Snap Pins (Power and EMG Envelope Output)\n\n\nEspressif ESP32-WROOM Module\nCH340 USB-to-Serial Converter\n2x Qwiic Connectors\n2.2kΩ Pull-Up Resistors\nButton\n\n\nReset\nGeneral Purpose/Bootloader\n\n\nLEDs\n\n\nPWR - Power Indicator\nCHG - Charge Status\n13 - User\nENV- Envelope\n\n\nJumpers\n\n\nPWR - Power LED\nSHLD - USB Shield\nREF - Reference Pin\nRAW - Raw EMG Output\nENV - Envelope Detector Output\nI2C -  I2C Pull-Up Resistors\n\n\nBoard Dimensions\n\n\n63.5mm x 38.000mm (2.50in. x 1.50in.)\n\n\n\n\nDocuments:\n\n\nBoard Dimensions\nHookup Guide\n\nAdvancer Technologies: MyoWare® 2.0\n\n\n\nQuickstart Guide (4.37MB)\n\nAdvanced Guide (9.00MB)\n\nPatents [1]\n\n\n\nMCP73831 Datasheet\nPolymer Lithium Ion Battery (40mAh)\n\n\nDatasheet\nMSDS\n\n\nMyoWare Arduino Library\nMyoWare 2.0 Ecosystem Page\n\n\n\n\n[1] Note: This product is patent protected.
