I bought the arduino FT232 converter from mouser, and was wondering what the jumper does. Picture of my board: [image] It appears to connect 5v to one of the pins on the FT232 chip. Any ideas on what it does?

Jumper on Arduino FT232 converter

Pin 4, which looks like VCCIO.

I'm guessing by default the IO pins are a 3.3v level but by adding the jumper it brings it to 5v?
