The RGB Matrix Backpack will be a small controller board to attach to 8x8 RGB LED matrices. It will accept input via SPI or I2C and control the display.

Rough Notes

  • High side could be 3 multiplexers (one for R, G, B) feeding PNPs for each column
  • Low side will be a multiplexer feeding 3904s for each row
  • Being able to plug them together in a 2D matrix would be awesome
