I have to output an analog signal that goes from 0v to 5v. I'm using a board that can only go from 0v to 3.3v. What can I buy that lets me convert 3.3v to 5v that works with analog such that 1.65v outputs 2.5v?
It has to be on a breakout board so that I can use it with the arduino. Thanks.
some amplifier, like transistor stage.

You could use 5v arduino as translator, or DAC module
Level shifters can convert 5 to 3.3 and/or 3.3 to 5
There are no ready made modules you can buy.
You will need to build something using an op-amp.
Not a continuous analog signal.
Opamp would work, or a DAC that outputs a 5V range.
