PCB Design: An LED Matrix controller board
This video is 16x speed of a capture I took while I was designing a PCB to more easily control an LED matrix. The board I designed is to drive a bicolor 8×8 LED matrix display, it uses a CPLD to accept commands and drive the LEDs (driving common rows through FETs in order to be able to supply enough current). I use Cadsoft Eagle for PCB design; In this video most of the components I required already existed in my library so most of the time here is spent on actual design. In my process, I first generate a schematic, connect everything that I’m sure about – Secondly I roughly lay out the board and try to work out how best to connect any pins that don’t have a specific connection requirement (like on CPLDs, FPGAs, and microcontrollers where one of several pins would work for the connections) – By optimizing the connections you can produce a much cleaner-looking board that has less need to jump between layers at lot to create the required connections. After deciding how to connect it, I wire up the connections in the schematic and get to routing, I may have to jump back and change some of my connection decisions depending on how it goes. At the end here I wind up with a pretty clean board that has all of the connections I need
After I created the video, I did also go back and expand the power traces, add a bypass capacitor which I had forgotten, and cleaned up a few other things, but this video shows the majority of the work that went into this PCB. I’m making this video …
