These instruction apply to the 1.2" Matrix only! If you have a Bi-Color or 0.8" square matrix, follow the links on the left side of the page.
When you buy a pack from Adafruit, it comes with the fully tested and
assembled backpack as well as a 8x8 matrix in one of the colors we
provide (say, red, yellow or green). You'll need to solder the matrix
onto the backpack but its an easy task.
WATCH OUT! THE MATRIX MUST BE INSTALLED THE RIGHT WAY!
First look for the line of text on the side of the LED matrix

Find the corner of the backpack with a filled in dot. Make sure that the text on the side of the matrix is on the same side as the filled dot

Slide the matrix into the backpack and flip it over. Triple check that the text is on the same side as the From Adafruit text

Now you're ready to wire it up to a microcontroller. We'll assume
you want to use a 4pin header. You can also of course solder wires
directly. Place a 4-pin piece of header with the LONG pins down into the
breadboard.
That's it! now you're ready to run the firmware!
