PIC18F Based 6 Channel DMX Transmitter

Step 2 Layout the Board

Perhaps the hardest part is laying out the circuit board. You have to consider where some things have to be, like the slide potentiometer, DMX receptacles, power jack, DIP switch ect. The RJ45 jack is for ICSP and is not necessary.

My slide pots had a 1.75" track and I spaced them 0.75" apart. Overall it is 4.5" x 4" x 1.5" high in the back and 0.5" high in the front. I chose the odd shape because I did not want to panel mount anything, I wanted all the components attached to the PCB. 

I don't think my layout is optimal. The DIP switch is in an awkward spot which caused a bit of problems when building the enclosure. But overall it is quite small, which was the idea.
