The version 1 hardware will be theoretically capable of 12-bit PWM output on each of 48 channels. This leads to a potential maximum of 4096³ (68,719,476,736) colours per three-channel pixel. This is patently ridiculous, and so the outputs will be downsized to just 8 bits thereby providing 24-bit colour (16,777,216 colours). | The version 1 hardware will be theoretically capable of 12-bit PWM output on each of 48 channels.
