dropControllerV3 fits fairly nicely on a 12×18 cm perfboard. It could be made smaller but the 12x18cm board allows space around the components. Perfboard is a good option for a one off semi permanent project.
You can find the circuit diagram here. The circuit diagram page also includes details about some of the components.
I tried to lay out the board in a logical fashion which I used as a stepping stone to creating a proper PCB. This included positioning the sockets so that the wires didn’t overlap each other.
Pertfboard preperation
Although most of the components are breadboard/perfboard friendly, a couple are not. Namely the 6 x 2EDGK terminal connectors and the DC-005 barrel jack.
The pins on the terminal connector are slightly too large for the holes on the perfboard and you may need to make the holes just a little bit bigger.
The barrel jack requires a bit more work and it requires filing out the middle of two holes.
Wire
For the power lines I used 24awg wire. For the rest of the circuit I used single core wire-wrap wire. Single core wire-wrap wire is ideal for use with proto-boarding and the wires can be very easily stripped,
When soldering long lines I use lengths of stripped wire. This makes creating long neat tracks fairly easy.
