I am currently powering a pi 3b+ Through a buck converter hung from a 24v p/s. I wanted both 5v (pi) and 12v. (LEDs). I’ve been getting some undervoltage warning from octoprint and my setup is the problem. At present. I have a 24v p/s (240w) feeding a buck converter outputting 12v. That, in turn, is. Split between a small string (5) of. LEDs and another buck converter outputting 5v to the arduino.
My question: being the guy with the fork in the toaster most of the time, was this so bad an idea that these warning messages are telling me so?
