STM32F4 Discovery and Pl2303 combination for UART

Thread starter #1

I was wanted to perform UART communication using the STM32F4 discovery and the PL2303 USB to TTL converter. However, since the PL2303 works with 5V logic (and I don't have the soldering skills to change pin 4s voltage by the way). Given that the STM32F4s pins are 5V tolerant, should I try to use it or is it going to damage the board?

Hi Nigel

Thanks for the reply.

I thought all pins were 5V tolerant. I will go and read up on this further before I attempt to perform UART communication.
