The daughterboards each have qty 3 UCN5832A ([[Image:Ucn5832.pdf]]) 32-bit shift registers (for a total of 96 bits) which drive an array of 32 by 48 pixels (for a total of 1536).  The theory is the other end of the LEDs are connected to 16 different power sources, making all the LEDs addressable (96 * 16 = 1536).  (The shift register does a current sink)
