The Adafruit Learning System Releases Bluetooth HID Keyboard Controller

Bluefruit2Adafruit’s Bluefruit EZ-Key enables you to create a wireless Bluetooth keyboard controller in an hour. The module acts as a Bluetooth keyboard and is compatible with any Bluetooth-capable device (e.g., Mac, Windows, Linux, iOS, and Android).

You simply power the Bluefruit EZ-Key with 3 to 16 VDC and pair it to a computer, tablet, or smartphone. You can then connect buttons from the 12 input pins. When a button is pressed, it sends a keypress to the computer. The module has been preprogrammed to send the four arrow keys, return, space, “w,” “a,” “s,” “d,” “1,” and “2” by default. Advanced users can use a Future Technology Devices International (FTDI) chip or other serial console cable to reprogram the module’s keys for a human interface device (HID) key report.

BluefruitEach Bluefruit EZ-Key has a unique identifier. More than one module can be paired to a single device. The FCC- and CE-certified, RoHS-compliant modules integrate easily into your project.

Pricing for the Bluefruit EZ-Key begins at $19.95. For more information, visit The Adafruit Learning System. Bluefruit EZ-Key tutorials are also available.
