How to use UART to connect STM32F407VG Discovery board with Windows PC

Hi,

I'm trying to use STM32F407 to develop bluetooth audio device. I use the cc2564c bluetooth board and CC256XEM-STADAPT board made by Texas Instruments. Now I need to use UART2 to connect the STM32 board with PC, but the PA2 and PA3 pins are used by the CC256XEM-STADAPT board. I'm trying to find an alternative.

Accroding to this artical, I think I should refer to the TWO PIECES OF WIRE part.

Refer to user manual, the PA2/PA3 should be soldered with U2 pin12/pin13.Is that recommended?

If I do so, that means I can use micro usb to connect the PC with virtual com port and send data through UART2?

To my knowledge, the STM32F407VG Discovery board is not recommended for audio applications and STM3240G-EVAL is recommended. Should I change to use STM3240G-EVAL?

My English is not good. Please forgive me if I said anything wrong.

Sincerely.
