Each PIXIE module is a gorgeous dual 5×7 LED dot matrix display. Easily chained and simple to address using just 2 GPIO, these are fantastic for making a small, fast and very cool display.
Lixie Labs have done a great job to make these as usable as possible. With full bitmap control and 7 bit PWM yielding 128 brightness levels, they’ve created a stack of documentation and resources to get up and running. There’s a library and examples for the Arduino IDE which, of course, opens these up for use not only with the Arduino family but also the ESP and more. If the full ASCII set and the additional 220 icons in the library (currency, weather, schematic symbols etc) aren’t enough, there is also an HTML page hosted in the repository with an interface where you can draw your own icon and download the code snippet. You’ll even find a driver for use with the Raspberry Pi.
Wrapped up in a neat PCB, the PIXIE hardware design allows them to mount horizontally with even spacing using an M2.5 hole under the display. There are some nice hardware touches in the repository, Eagle footprints are available, and also a collection of STL files to print mounting plates for between 2 and 10 PIXIE.
On the product page there is a nice GIF of a display in action, but we heartily recommend checking out the video below, at the highest quality setting you can, to see just how lovely these little PIXIE are.
