Bluefruit EZ-Key – 12 Input Bluetooth HID Keyboard Controller. In stock and shipping now! Create your own wireless Bluetooth keyboard controller in an hour with the Bluefruit EZ-Key: it’s the fastest, easiest and bestest Bluetooth controller. We spent years learning how to develop our own custom Bluetooth firmware, and coupled with our own BT module hardware, we’ve created the most Maker-friendly wireless you can get!
This breakout acts just like a BT keyboard, and works great with any BT-capable device: Mac, Windows, Linux, iOS, and Android. Power the module with 3-16VDC, and pair it to the computer, tablet or phone just as you would any other BT device. Now you can connect buttons from the 12 input pins, when a button is pressed, it sends a keypress to the computer. We pre-program the module to send the 4 arrow keys, return, space, ‘w’, ‘a’, ‘s’, ‘d’, ‘1’ and ‘2’ by default. Advanced users can reprogram the module’s keys using an FTDI or other Serial console cable, for any HID key report they desire.
You can pair multiple Bluefruit’s to a single device, each one has a unique identifier. These modules are FCC & CE certified and are RoHS-compliant so they are easy to integrate into your project.
If you want to have better control over the data sent, connect a microcontroller to the RX pin at 3-5V logic level, 9600 baud, and send ASCII data: it will be ‘typed out’ character by character. We also have support for various non-printable characters such as ESC, Shift, F1-F12, etc. as well as toggling the virtual keyboard on iOS.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
