I'm trying to connect a TTL-232R USB-UART Converter to an STM32F3DISCOVERY board. I've connected the TX/RX wires on the TTL-232R to PB10/PB11 on the STM32F3DISCOVERY board. I have the board connected to my laptop over USB.
Do I need to connect the 5V/GND wires on the TTL-232R? Or are these signals already provided by USB?
Any help would be much appreciated.
