The circuit board presented here with soldered and flashed ATmega is part of the USB DMX interface developed by DMXControl Projects e.V. This allows DMX-compatible lighting systems to be controlled from a PC using software. The interface has both a DMX output and a DMX input, each of which can process 512 channels simultaneously.

Further information about the interface and the project archive with assembly instructions can be found on the project page.

ATTENTION: The Nodle U1 firmware has already been installed and tested! Please observe ESD protection during assembly!
