Can support PWM up to 11Bit per channel, providing true 24bpp color with CIE1931 profile. Supports 3 chains with many panels each on a regular Pi. On a Raspberry Pi 2 or 3, you can easily chain 12 panels in that chain (so 36 panels total), but you can theoretically stretch that to up to 96-ish panels (32 chain length) and still reach around 100Hz refresh rate with full 24Bit color (theoretical - never tested this; there might likely be timing problems with the panels that will creep up then). With fewer colors or so-called 'outdoor panels' you can control even more, faster.
