Need a cheap display for your Raspberry Pi? Or perhaps you’re building a Times Square for ants? Then check out this guide by Adafruit’s Tony Dicola.

The project is based around Adafruit’s RGB Matrix HAT for the Raspberry Pi, which makes it easy to power and output to daisy chained LED matrices. Tony says a Pi 2 can handle up to 12 32×32 LED matrices at once. Because of how the image is output, the matrices can be put together only as a rectangle. Further, the display’s aspect ratio needs to be as close as possible to the Pi’s output to reduce distortion. You can also program it so that the matrices show only a portion of the Pi’s output.

Head to Adafruit’s website for the complete guide.
