These modules can be mounted flush side-by-side to extend them far beyond the 8x8 matrix. For example, you could have a 8x32 matrix! At the core is a MAX7219 - a very well documented chip in the Arduino community (along with ever other flavour of micro controller).
The SparkFun LP55231 LED Driver Breakout is a self-contained solution for developing and deploying the nine-channel I2C LED controller. Remarkably simple, the breakout...

The SA23-12EWA is a 57mm red high efficiency Single-digit Numeric Display with white diffused lens. The high efficiency red source device is made with gallium arsenide phosphide on gallium phosphide. It has low current operation and high light output. It easily mounts on PC boards or sockets.
This is the FemtoBuck, a small-size single-output constant current LED driver. Each FemtoBuck has the capability to dim a single high-power channel of LEDs from 0-350mA at up to 36V while the dimming control can be either accessed via PWM or analog signal from 0-2.5V. This board is based off of the PicoBuck LED Driver, developed in collaboration with Ethan Zonca, except instead of blending three different LEDs on three different channels the FemtoBuck controls just one.
The PicoBuck LED Driver is an economical and easy to use driver that will allow you to control and blend three different LEDs on three different channels. By default, each channel is driven at 330mA; that current can be reduced by either presenting an analog voltage or a PWM signal to the board. Version 12 of the board adds a solderable jumper that can be closed to increase the maximum current to 660mA. The new voltage regulator also increased the voltage rating on the various components on the board, allowing it to be used up to the full 36V rating of the AL8805 part.
Sometimes when you have too many choices, it’s hard to make a good decision. In fact, there are times when you just want a bag of LEDs, just one of each, that’s all you want. Well too bad, you are getting two of each! The LED Rainbow Pack contains two diffused 5mm PTH LEDs of each color of the rainbow, red, orange, yellow, green, blue, and purple. This is a great way to sample each one and decide what you really need or just to add a whole bunch of color to your next project.

Easy e-paper finally comes to microcontrollers, with this breakout that's designed to make it a breeze to add a tri-color eInk display. Chances are you've seen one of those new-fangled 'e-readers' like the Kindle or Nook. They have gigantic electronic paper 'static' displays - that means the image stays on the display even when power is completely disconnected. The image is also high contrast and very daylight readable. It really does look just like printed paper!

Make your own smart LED arrangement with the same fancy side light integrated LED that is used in Adafruit's HalloWing M4, and side-emitting NeoPixel strip and pixels. These bare LEDs are a great alternative for folks who have loved and used Adafruit NeoPixel strips for a few years but want gorgeous, glowy light emitting at 90 degrees
