|The DMX Relay Receiver is a DMX module that mounts four relays; they can be individually controlled using a DMX master like TinkerKit!'s DMX Master Shield. It requires 12V and each relay supports up to 220V at 10A. A single master can control up to 512 receivers individually (128 of these boards for example) sequentially connected.|
The DMX Relay Receiver works also as a standalone USB board; in fact it mounts a micro-usb connector and the same microcontroller as the Arduino Leonardo.
