This cool new DMX module from Tinker (the team behind the immensely popular Arduino controller) is a device that can receive DMX messages and control many different types of lights. It is powered by 12 volts DC and set inside a DIN enclosure. DMX messages are converted into PWM signals driving 4 power MOSFETs and DMX address is set via the onboard DIP switches. Pretty cool piece of hardware with some code samples to boot!

DMX stands for “Digital Multiplex” (protocol)
the page after the link says:
“Up to 128 of these devices can be connected on a single cable to control up to 512 groups of lamps.”
However, the DMX protocol is not so restricting.
Each DMX “universe” has 512 channels. 128 came from 512 divided by the 4 channels this device can “listen” to. but you can put as many devices as you want on a “universe”. you just have to share the channels. each device is addressed to specify the first channel that it listens to. If you like, you can have multiple devices listening to the same channel.
