BBI-64 Button Box Interface

Price: 34.99GBP



USB buttons, switches and encoders interface board with simple connections. Works on Windows, Mac and Linux.

Build your own gaming device - flight panel, button box, music controller, robot controls and anything else that needs interfacing to a computer.

Does not require any drivers - works immediately after plugging into USB port.


Up to 64 buttons or 32 rotary encoders connected directly to their dedicated inputs.
Each encoder uses two button inputs.
There is no need to use any matrix wiring at all.
Four buttons can be assigned to POV Hat switch.

Connection to PC

The PCB has a standard USB-B type connector for connection to PC or Mac. Plug it in and use straight away.

Fully self-contained interface

Natively supported by Windows  10/ 8/ 7/Vista/XP/2000 32/64 bit and Mac OS X. Also works on Android devices via USB link. - Forget drivers - just plug it in and it's ready to go.

Unique serial number helps Windows remember each device - Ever unplugged a joystick and had Windows lose calibration settings? This controller retains settings even if plugged in a different USB port or if you use two and swap them over.
Also allows you to connect and use more than one at a time.

Powered by USB bus (+5V - 100mA) so no external power supply is needed

Full-speed 12Mbps USB connection.

Compatible with any game that can detect and use generic joysticks - MS Flight Simulator, X-Plane, rFactor, iRacing and other driving games etc.

Proudly designed and made in the UK.

Connecting Rotary Encoders

Support for up to 32 rotary encoders - A pair of digital inputs can be connected to a rotary encoder. All main types supported (1, 2 and 4 pulses per detent. Check the datasheet of your encoder to find out which type you have). Once connected, download our encoder software in the product downloads tab and set the pair of inputs to the encoder mode you require. Always use odd number for the first input, ie. 1-2, 3-4, 59-60, etc.

Can the BBI-64 be turned into keyboard or other device? - Mapping button presses to other functions such as mouse/keyboard or hat switch controls can be done using third party software. Look in the downloads tab for software solutions.

Check data sheet of the component you wish to connect for the correct pin out - The PCB is labelled clearly to show where each pin from your component should connect.

Once you have connected everything you need - Connect to a PC or Mac using a standard USB A to B cable and the device will be recognised as a generic game device named - Button Box Interface BBI-64. You can then assign your controls using your chosen game or software as you would with any other game controller. That's it!
