This product has been retired from our catalog and is no longer for sale. This page is made available for those looking for datasheets and the simply curious.
Description: Replacement: None. We’re no longer making this board, but check out our other buttons and switches. This page is for reference only.
Connect ALL the buttons! The Button Pad Controller USB was designed to control an entire multi-board system of Button Pad Controllers through an easy to use API over a USB connection. The board is 4”x4” and has 16 tri-color LEDs and 16 corresponding button pads (i.e. The button pads surround each LED). The USB Button Pad Controller is designed to communicate with up to 9 other Button Pad Controller SPI boards. The default firmware uses a 24 bit color scheme for each LED. Each board comes configured to work as a standalone unit and must be reconfigured for multiple board systems.
We do not sell the frames shown in the photograph. We put those together for our own use as a demonstration of what two units (USB unit and a SPI unit) look like, boxed up together.
Unit comes fully assembled and tested as shown. Unit does not include top button pad (listed below).
Note: If you want to use this as a slave board, you will need to use an AVR programmer to erase the master ATMega328. Use the ‘Master Prog.’ ISP header to do so.
Note: We’re using new RGB LEDs which have the blue and green pins swapped. When setting the LED color, you’ll need to swap the blue and green values in the command structure. Visually, nothing on the board has changed.
Dimensions: 4 x 4”
