Capabilities

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).

Components

Requirements, per board:

  • 3x TLC5940 16-channel PWM LED drivers
  • 3x 2kΩ resistors
  • 1x 10kΩ resistor
  • 16x 4-pin headers
  • 16x RGB LEDs
  • 1x Arduino

Future requirements:

  • 1x TUSB2046B 4-port USB 1.1 hub
  • 3x USB female sockets
  • 1x USB male plug
  • 3x 4-pin recessed sockets
  • 1x 4-pin plug
  • 1x 5v ?mA power supply
