Hi everyone, I'm trying to build a wifi project with Arduino UNO, and I've been told to use a USB to Serial adapter based on chip CP2021.
The problem is when I went to the only store that sells these products in my country they had ran out of stock and offered the FT232RL, which -according to their words- the only differences with the former are: 1) You can select between 3.3V and 5V supply, and 2) USB port has changed for a Mini USB port.
Will that new module suit for a basic project? Should I try to get the CP2021 maybe buying it online or awaiting for that store to renew its stock?
From a functional point of view the FT part will provide the UNO to USB function. There might be a few signals between it than the processor that have to change. And if using Windows the driver will be different.
However if the instructor has a specific reason for the CP2021 then you might ask first. For instance if they will be "testing" each they may want all the drivers to be the same. I would check before switching.

Thanks a lot John! Your reply helped me understand the differences better. I will check with the instructor then.
CP2102.
