The BLE Shield adds Bluetooth Low Energy (BLE) connectivity to your Arduino, letting it communicate wirelessly with smartphones, tablets, and other BLE central devices. Compatible with Arduino Uno, Mega 2560, Leonardo, Due, and other 3.3V/5V-compatible boards.
Use it to build mobile-controlled Arduino projects, stream sensor data to a phone app, or use your mobile device as an internet gateway for your Arduino.
Key Features
- Bluetooth Low Energy – Connects Arduino to smartphones, tablets, and BLE central devices
- Broad Compatibility – Works with Arduino Uno, Mega 2560, Leonardo, Due, and compatible boards
- Dual Voltage – Operates at 3.3V or 5V for wide Arduino compatibility
- Shield Form Factor – Stacks directly onto standard Arduino headers
Use Cases
- Control Arduino pins via a custom mobile app
- Send sensor data from Arduino to a smartphone for processing or display
- Use a mobile device as an internet gateway for Arduino projects
Ideal For
- IoT and wireless projects requiring low-power Bluetooth connectivity
- Mobile app integration with Arduino hardware
- Wearable and portable Arduino builds
Jargon buster
Plain-language definitions for the technical terms used above.
- BLE
- BLE stands for Bluetooth Low Energy, a Bluetooth mode designed for lower power use and modern phone compatibility. It matters because BLE support can make the module easier to use with Apple devices and battery-powered projects, though it may behave differently from classic serial Bluetooth.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
