Comes with one fully assembled and ready to go panel, and a 10-pin IDC cable. You will need a microcontroller to control the display, our tutorial uses an Arduino but nearly any microcontroller with 3 digital output pins can be used. If you want to chain two displays, you can use the two IDC cables in the packages to connect them. But for 3+ chained displays you will need more cables — check the tutorial, search for «How many Cables do I need?» for an explaination
And of course, we have written a full tutorial and Arduino library that not only takes care of controlling the display, it also intelligently handles chained displays, so that they appear to be one long matrix. The library has functions for drawing pixels, lines, rectangles, circles and text. You’ll be making it light up in 15 minutes!
- Requires 5V power
- 3 digital pins for one panel
- Chainable up to 8 displays, each display requires an extra CS pin (so 8 displays requires 10 digital pins)
- 4.5″ x 3.5″ x 0.7″
- 4 x 0.125″ drill mounting holes
- HT1632C driver chip
