I am working on a flight control board inspired in this Sparkfun board:
It is basically an Arduino UNO with a FTDI chip instead Atmega8u2 as USB-UART bridge. It manages power stage in order to allow both USB and Jack connector at same time. In my device I want to allow both USB and ESC power options. My question is, can I replace the Jack connector and the LDO and just connect the 5V output of my ESC in the 5V wires of that schematic?
Something like this:
I actually don't know how smooth ESC's output voltage is. Maybe it is a good idea to let the LDO and connect the ESC over the jack input.
