preparing the image

Preparing an image can be done in software like Fritzing or KiCad. There you will be able to produce the right pin out layout for specific components like arduino and other modules. This allows for the components to be soldered directly onto the board.

1. In fritzing, open the breadboard tap, drag in the components of your circuit and connect them with wires. this will automatically generate a schematic drawing and PCB layout.

2. Make sure everything is connected properly and then open the PCB tab to arrange the circuit as you please.

3. Export as image (svg/png).

4. Edit your image in an image editor of choice to create a black on white vector image.

lines can be merely decorative or functional, connecting different pin outs.
