The DMX MosFet Receiver is a DMX module that mounts four mosfets; they can be individually controlled using a DMX master like TinkerKit!'s DMX Master Shield. Each mosfet supports up to 24V DC and the board runs at a range from 12V to 24V. A single master can control up to 512 receivers individually (128 of these boards for example) sequentially connected.
The DMX Mosfet Receiver works also as a standalone USB board; in fact it mounts a micro-usb connector and the same microcontroller as the Arduino Leonardo.
