Cypressboard voltage

I wired a pot into the cypress board and Its working,but when I took a voltage test I am only reading 3.321 volts on the driverstation and multimeter, is there anyway to get the full 5 volts that is supplied from the usb port?

Re: Cypressboard voltage

There is a jumper setting that allows you to change VDDIO from a 3.3V supply to a 5V supply; see the notes on VDDIO in the FRC spec sheet:

Quote:

− V+ output @ 5V:
o Jump pins 1,2 on J1 and pins 1,2 on J4
o Powered directly from USB Vbus

The Cypress has labels on the corresponding jumper pins for you to identify which ones you have to switch; this document has a diagram of which pin headers are J1 and J4.
