I certainly agree that breakout boards can really help (especially since most of the most interesting parts are only available in SMD packages -- 40 years ago they were almost always in DIPs). The Qwiic system can also be of tremendous help.<p>I realize that for some projects, such as yours, the hardware is pretty simple, and even if you manage to do something like get the ON/OFF on the relay inverted, you can deal with it in software, but I've seen way too many designs where that's not true, and had they gone directly to a PCB, you'd test the results for maybe 10 or 15 minutes before deciding you'd just generated a thousand-dollar pile of scrap.</p></p>
