Adafruit Bluefruit EZ-Key - 12 Input Bluetooth HID Keyboard Controller

Create your own wireless Bluetooth keyboard controller in an hour with the Bluefruit EZ-Key. This user-friendly module acts as a Bluetooth keyboard, compatible with any BT-capable device such as Mac, Windows, Linux, iOS, and Android.

This versatile device is powered by 3-16VDC and connects effortlessly to computers, tablets, or phones. The 12 input pins allow button presses to trigger keypresses on your device, pre-programmed to send default keys like arrow keys, space, and 'w', 'a', 's', 'd'.

Advanced users can reprogram keys for custom HID key reports using a Serial console cable. You can also pair multiple Bluefruits to a single device, each with a unique identifier. This module complies with FCC & CE certifications and RoHS standards for easy project integration.

Connect a microcontroller to the RX pin at 3-5V logic level for enhanced data control, typing ASCII data character by character. Support extends to non-printable characters and toggling the virtual keyboard on iOS. Ensure Bluetooth v2.1 or higher compatibility for optimal functionality.

The latest v1.1 update introduces mapping keys to mouse buttons and movements, including 'over the air' remapping without cables. The v1.2 update adds support for multimedia keys like "volume up" and "play/pause," further enhancing your custom keyboard experience.
