This universal op-amp PCB should be in the parts bin of every electronics tinkerer on the planet. Everyone who works with electronics has been in a situation where they need to amplify a signal. The op-amp is an obvious choice for this task but what’s the fastest and easiest way to wire it up? In a pinch you could use a breadboard with something like an LM741 op-amp and some through hole resistors to get the job done. For something a bit more permanent you could solder the circuit onto some strip board. But a really slick solution is this Swiss Army Knife PCB that is a one-stop shop for all of your op-amp related needs.
This board supports two quad op-amps each with a bypass capacitor. All you need is an SMT op-amp and some resistors and you will be able to quickly and easily put together any of the common op-amp circuits. The creator of the board, land-boards, has a wiki page with some of these circuits and how to wire them using this PCB. If you’ve ever made an op-amp circuit on a breadboard that turned into a bird’s nest of wires (and likely didn’t work properly), then this is the board for you!
