Same logic high ,but different voltage

Hi,guys. So why different pins have different voltage, while they are all logic high. (In my experiment,one is 1.14V, the other is 3.3V) Appreciate for any reply

I got that. It is not FPGA which supports 5V in cyclone family.

It is a Nios II development board cycloneII EP2C35 device.

The pin is 12th of J15. Any solutions?
