PCBWay 3rd PCB Design Contest

two wire (DMX) interface module

This module uses two wires to connect a 4 digit 7 segment display with 4 buttons and 3 status leds. With this module you end up having a lot more free pins on your arduino which you can use for other purposes. Besides more free pins this module also remembers the output state and can dim the display, this reduces CPU load so you have more time to run the main program. The PCB was my first PCB and it ended up really great, The next time I would make some minor changes to improve the project.
