I would like to use one of the UARTS on the STM32F4 to connect the MCU to a Bluetooth SMART controller. I was wondering if anyone could tell me if there is any access on the board to one of the UARTs so that i can solder wires to pull the RX/TX lines out. If so, which UART is it? I'm sure going through the schematic would tell me this, but I'm a noob to the really lowlevel embedded stuff and I've been looking at the schematic for a while and still can't figure it out. Any help would be much appreciated.

Thanks

Have you looked at the schematics?

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

The manual for the STM32F429I-DISCO does enumerate a pin list, if you can't decode the schematic this list would be where to start.

As I recall USART1 PA9/PA10 are available on this board.
