Quoted from benheck:Alien's electronics were very over-built. They used MCUs on their node boards that were about 4x more powerful (ahem expensive) than they needed to be. On top of this they did noob stuff like use an expensive FTDI232 converter IC even though the MCUs had built in USB support. I know this because it's the same noob stuff I did early on.
Also yes, a BBB would probably struggle with HD LCD video assets.
Does CGC uses LCD display or dot matrix?
I wonder if their 256 x 64 dots is a dmd as well
