I was laying out a PCB for some video experiments. While doing this I thought it might be interesting for others, too.
The idea is that you an solder a prototype and connect it easily to the headers with wires or jumpercables. The voltage sources are placed near the rails of the ‘breadboard’ , so you can connect +12v or +5v to them.
The GND rails are pre-connected.
It has these features:
2x input buffer with jack
1x output buffer with jack
1x comparator with jack
2x aux jack
the outs and ins of these have pin headers.
a breadboard style solderpad grid
+0.5v, +1v, +5v, +12v, -12v, GND headers
eurorack power connector
note: the values in the schematic are not yet corrent. I’ll post bigger images later
Any suggestions on additional features?
I was thinking :
an extra comparator (negative high for CMOS reset, maybe)
a big connection header instead of those loose pads
negative voltage sources like -1v ?
