Gheo Electronics, Tinkerkit DMX Master Shield - Arduino Programmable DMX Lighting Controller - Red Fiberglass Stage Light Controller

Works perfect for serial DMX 512 output. The XLR connectors do not come soldered which I was glad to see. Didn't want them. Have this controlling 72 channels of 12v LEDs for a christmas display. FYI. The shield communicates on pin 3.#include "DmxSimple.h" // The most common pin for DMX output is pin 3, which DmxSimple //uses by default. If you need to change that, do it here. DmxSimple.usePin(3); // DMX devices typically need to receive a complete set of channels //even if you only need to adjust the first channel. You can //easily change the number of channels sent here. If you don't //do this, DmxSimple will set the maximum channel number to the //highest channel you DmxSimple.write() to. DmxSimple.maxChannel(DmxChannels); //DmxSimple.write(1-512,0-255) //1-512 DMX channel, 0-255 is brightness value.

The picture shows the DMX plugs - But they are NOT soldered to the board

Not documentation and poor packaging but works okay

good product!

Arrived quickly, as advertised.
