Hello forum,
I am looking for an alternative power solution for a RPi 4 without a wall adapter, as it is not possible to use one for my project due to it being a mobile hardware application and not enough space.
I also have a PSU that converts 230 V AC to 24 V DC, so I am trying to design a buck converter that outputs 5.1 V DC at 3 A.
Which solution is most likely to power the RPi 4 without causing undervoltage issues? Is it via header pins or USB-C?
Thank you
