I am still busy with my DMX splitter. The circuit is (at least for me as beginner) quite exhausting to hand-solder. See circuit below (sorry for my 'artwork' as some used to call it, it benefits me a lot to locate exactly the positions to wire).
I spend several hours to one DMX output PCB. As you can see 4 of them are quite similar.
I was wonder, how worthwhile it can be to make some 'default' building block DMX and/or MIDI circuits and order them.
Let's assume I want to put both a DMX in and DMX out on one PCB, but I want to hand wire the connections between them, to be able to use them
- as DMX input only (and not using the DMX output part)
- as DMX output only (and not using the DMX input part)
- as DMX input and output (possibly by handwiring or use some jumpers to be able to connect the input and output
The PCB I need to order would be a combination of what is shown in the left/right PCBs marked with BOTTOM (which is a DMX input (left) and DMX output (right).
The reason is that ordered PCB normally have to be ordered by 10 so I benefit from equal designs.
The same later for when I'm going to incorporate MIDI (like making a MIDI in + out + thru on one PCB, but being able to use them in any combination.
Would this be useful (with the use of jumpers) or is it better to make the PCB's minimalistic?
(btw, for now I'm continuing handwiring, because I want to have this project finished, getting some more experience with soldering, and also because I never ordered a premade PCB, no knowledge about Kicad or other application that can generate Gerber or alike files needed to order a PCB).
