If you need to add one or two SMT chips to your breadboarded prototype, [Travis Hein] has you covered. He designed a set of small SMD adaptor boards for various SOIC, SOT23, and DPAC patterns using KiCad. He has released them as open source, so you can feel free to use them or modify them as needed.
Normally we don’t see people bypassing the schematics when designing a PCB. But we can agree that [Travis] has found a situation where going direct to PCB makes more sense. He just plops down the package in Pcbnew, adds some pin headers and wires everything up directly on the PCB. (But don’t worry, some of you may remember [Travis] from his earlier SSR mains switching project, which demonstrates that he can indeed draw proper schematics.) We know there are more people out there who prefer to go straight to PCB layout… [mikeselectricstuff] comes to mind. If you could yourself among this tribe, let use know your reasoning in the comments below.
We wrote about a similar universal breakout boards for SMD parts back in 2016, which is a single breakout board for two- and three-pin jelly-bean components. If you paired some of those boards with [Travis]’s breakout boards, it would make a great combination to keep in your prototyping gadgets bin. Consider this project the next time your favorite PCB shop has a sale.
