<!-- SC_OFF --><div class=“md”><p>I’ve been away from microcontroller projects for a while, but I recently managed to drag some parts out to try some quick experiments as time allowed. I had one of those breadboard power supplies that lets you put 5V on one set of rails and 3.3V on the other, but I must have let a loose wire short something, because I managed to burn it out. </p> <p>I’ve got some level shifters and buck/boosts, but I can’t get to them right now, because we’re doing some home renovations, and most of my electronics stuff is packed away and hard to get to. Right now, it would just be easier to order something from Amazon, eBay, Adafruit, AliExpress, or whatever. </p> <p>What’s everyone’s preferred quick & easy prototyping power solution for 3.3V microcontrollers (ESP32, et al) with LED strips?</p> </div><!-- SC_ON --> submitted by <a href=“https://old.reddit.com/user/dougalcampbell”> /u/dougalcampbell </a> <br/> <span><a href=“https://old.reddit.com/r/FastLED/comments/14udxgi/power_for_5v_3v3/”>[link]</a></span> <span><a href=“https://old.reddit.com/r/FastLED/comments/14udxgi/power_for_5v_3v3/”>[comments]</a></span>
