I have an Eleksmaker laser cutter which has a board with a 12V output (see top of image).
I would like to power my RaspberryPi using this 12V output.
What is the advantage of powering the RaspberryPi over microUSB instead of hooking 5V onto the GPIO pins?
Though I can easily cut a microUSB cable in two and attach the wires, how can I reduce the voltage from 12V to 5V?
What other things should I be concerned with, or would I need to verify, before trying this out reasonably safely?
