I have an issue, very trivial, i am a newbie.

I want to interface LPC1769 to PC. And for that purpose i have bought a PL2303 module and i also have a CP2102 based USB to serial converter.

If i am correct LPC1769 works on 3.3v.

When i measure the voltage on the Tx and Rx lines on the USB to serial converter i see that it i s ~5v.

Can i connect these modules to UART TX and Rx on the LPC??

will the 5v harm the IO pins??

Please answer.
