If you're looking for help on how to assemble one of our backpack-enabled LED displays, have a look at our earlier guide, Adafruit LED Backpacks. It contains a lot of complimentary information on these displays, including step by step soldering and assembly instructions.
This guide works all Raspberry Pi Models that have headers. That is every model except for the compute modules which do not have headers.
While we already have a great tutorial and Arduino library for our handy and easy to use LED backpacks, if you're wondering how you can make use of backpack-enabled LED displays on the Pi, this guide will help you get started!
