LED Tiles

Overview

LED tiles are just that, a piece of PCB with five RGB LEDs on them and a single white LED. They use a 16 channel LED driver with a SPI interface so that many can be driven from the same microcontroller. The idea is that you can play with just one, or tile them on a wall or other surface for neat visual effects like fading a color across the surface. The size of the PCB is yet to be determined. Initial prototypes will be through-hole parts, but further revisions will be on real PCBs with SMT parts.

Parts List

These two versions may be merged at some point or the version I create may use parts from both.

• 1 white through-hole LED
• 1 16 channel DIP LED driver

Production

• PCB
• 5 Tricolor SMT LEDs
• 1 White SMT LED
• 1 16 channel SMT LED driver
