This is the PCB for the new Led Matrix Enclosure Isolated Power Supply, 2 Isolated RS485 ports, Micro SD Card slot, USB Host, Ambient Light interface, and buffers for the LED Matrix.

Uses a Haoyu LPC1788 module (NXP ARM Cortex M3 with more memory than you can poke a stick at).

We will design a version with Ethernet later this year.
