Please leave inline comments below if you have any questions or come across anything that looks incorrect!

If you are interested in building a display with more than 4 modules, please see the notes at the bottom of this document about how the controller PCBs can be chained together for up to 12 modules controlled by a single Arduino Uno. If you have any questions, please feel free to reach out to me (scottbez1 at gmail or just mention me @Scott B in a comment on this doc) and I would be happy to give you some tips and help make sure you order the right parts.

Note: AliExpress listings have a tendency to change or disappear, or you may end up getting a different or inferior product even if you use the same product listing that has worked before (ask me how I know 🙁). These are suggestions only - they worked at one point but there is no guarantee you will get the same quality product when ordering again! Also, if you've never ordered from AliExpress before, keep in mind that most items will take 3-4 weeks to arrive; you can often find similar parts for a higher price on Amazon or ebay if you'd prefer faster shipping.
