Change PIC18F45K50 power supply from 3.3v to 5v

Unread postby Idan_VT » Tue Jan 23, 2018 2:56 am

Hi guys,
I have the PIC18F45K50 microcontroller and I want to change the power supply from 3.3v to 5v via pins.
according this link: https://wiki.odroid.com/accessory/add-o ... usbioboard

"The user can choose either 3.3v (default) or 5v supply by the position of R1 (soldering is required to change). For easy soldering, R1 size is 1608(0603)."

I know what is R1, can you tell me how the soldering should be? what I need to solder exactly? do you have example image?

Thanks

Desolder the R1 resistor and shift it to VBUS location and solder it again.
