I have a couple of these FT232RL breakout boards direct from China, look like they are Folger boards. I measured the voltage between Vcc and GND, and it's 5V from the factory.
It has 3.3V pad on the back. I'd like to change this to a 3.3V.
So do I solder the 3.3V pad to the center pad? Do I have to make a cut across the 5V trace?
