I'd like to power an arduino nano with 5v and power some higher-current devices (e.g. motor) at higher voltages (e.g. 9v). I'd like a single power source for the whole project, ideally a barrel jack.
I have this in mind: -
I'd like to use a barrel jack with the adaptor set at 9v. These would be VCC1/GND and used to power the higher current and voltage motor at 9v.
I'd like to then take the 9v VCC1 and GND as an input to the LM2596, with the adjustor set to 5v output. These 5v outputs, VCC/GND, would then power the rest of the circuit including the nano (via pin 27).
Is this approach viable?
I'm concerned that current drawn from the motor upstream of the LM2596 will mess with the 5v output.
Any pointers would be much appreciated.
