As muscle activation increases, the LEDs climb further up the board.It snaps onto the top side of the MyoWare 2.0 Muscle Sensor using the onboard snap connectors, with a power switch to turn the sensor on from the shield. A 40mAh single-cell LiPo battery is soldered to the board, helping provide cleaner battery-powered measurements and avoiding a current path back to mains-powered equipment.Charging is handled through the USB Type-C connector with a dedicated LiPo charge circuit, and the board includes status LEDs for CHG, FULL and VIN. It fits into the MyoWare 2.0 ecosystem for solderless stacking with compatible shields and connection to a microcontroller analogue input.Documentation available for this ecosystem includes a hookup guide, quickstart guide, advanced guide, MCP73831 datasheet, battery datasheet and MSDS, ArduinoBLE reference material, a GitHub example repo and the MyoWare 2.0 ecosystem page.Features:Signal display: Blue 10-segment bar graph shows the magnitude of the measured muscle signal.Stackable design: Snap connectors allow the shield to stack on the top side of the MyoWare 2.0 Muscle Sensor.Battery powered: Built-in LiPo battery can power the MyoWare 2.0 Muscle Sensor.USB charging: Recharge the battery through the USB Type C connector.Status indicators: Includes charging and power status LEDs for CHG, FULL and VIN.Solderless ecosystem: MyoWare 2.0 shields snap together with a compact low profile.Analogue measurement path: The MyoWare 2.0 ecosystem can connect to a microcontroller's analog input to measure raw, filtered, and rectified electrical activity of a target muscle.Specifications:Input Voltage: 5V via USB Type C ConnectorOutput Voltage (e.g. "VIN") Nominal Voltage: 3.7VOutput Voltage (e.g. "VIN") Fully Charged: 4.2VPower Switch: Power SwitchBuilt-in LiPo Battery: Built-in LiPo BatteryBuilt-in LiPo Battery Rated Capacity: 40mAhBuilt-in LiPo Battery Nominal Voltage: 3.7VBuilt-in LiPo Battery Max Charge Current: 1C (40mA)Charge IC: MCP73831 Single Cell LiPo Charge ICCharge Rate: Set to 40mAForm Factor: MyoWare® 2.0 Muscle Sensor Form FactorSnap Pins: 3x Female Snap Pins (Power and EMG Envelope Output)LEDs: VINLEDs: FULLLEDs: CHGLEDs: 2x 5-Segment BarsBoard Dimensions: 46.15mm x 38.00mm (1.82” x 1.50”)Revision Changes: This revision of the MyoWare 2.0 LED Shield includes a 2-pin, 1.00mm pitch JST-SH connector.MyoWare and the LED Shield are not intended for use in diagnosis, cure, mitigation, treatment or prevention of disease. It is suited to education, prototyping, workout feedback and creative myoelectric projects. **Product Type:** Sensor Shield ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD0bUCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--19de5a74c8b7f9214fff0e03a66ab6c2d1b143e5/21869-_DEV-_01.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD27UCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--b6f26bec7e34ce22366f2be242e9075f98cd8c47/21869-_DEV-_02.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD5LUCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--a317ef90813cd1e822d26fa68e8f5c22f1607b75/21869-_DEV-_03.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD77UCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--65bb76b89dc2f8bd7b429434cf6e832c6e7a09c4/21869-_DEV-_04.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
