Hey guys and gals, I have a quick question about power supplies. I'm about to purchase a 5V/2A Wall charger. For my specific project, I have a USB connected to the mBed for Serial Communication so it's getting power from there. I then have ANOTHER USB cable powering something that requires 3.3V, and then I have a wall charter that is 5V/.3A. I want to get rid of the 2nd USB cable and replace the .3A -> 2A.
My question is this: Can I take the 5V/2A charger and put it into Vin on the mBed with the USB connector in as well? Then can I use the 3.3out and Vout to power my other items? I don't know what happens if you power the mBed from USB & Vin and don't want to damage it.
Thanks!
