Hi,

I'd like to connect STM32VLDiscovery to my laptop USB via USART.
Everywhere I see that to have RS232 on board it is not sufficient to connect USART pins with DB9 connector. RS232 <-> TTL converter is needed (like MAX3232). 
But if I want connect only to laptop USB (don't need higher voltage than 5V) and I have USB<-> RS232 cable based on Prolific PL-2303. Isn't it enough to connect DB9 directly to Discovery?
