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 RGB LEDs
- 1x Arduino
Future requirements:
- 1x TUSB2046B 4-port USB 1.1 hub
- 3x USB female sockets
- 1x USB male plug
