USART/UART PINs on STM32F429i eval board

[Embedded_Andy]

Hello ,

Does anyone use STM32F429i eval board ?
The user manual (shown as the screenshot below) for my F429 eval board says it has 4 USART ,4 UART. But I can only find 1 DB9 male port marked as USART1. 

Also, when I use CubeIDE to configure USART1, it automatically enabled PB6 and PB7 for TX and RX. But on the user manual , the schematic clearly says RS232_TX for USART1 is PA9, RS232_RX is PA10.  

That's really confusing... 

I am not able to find 4 USART connections, nor can I configure the right PIN numbers for USART1.  

I tried to verify the Pin numbers from the github example folder, it seems they don't have the PIN number either.

A USB to UART adapter has been used by many, rather than using RS232, e.g.

Most Nucleo boards connect one of the micro's USARTs to the on-board ST-LINK debugger, which provides a Virtual Com Port ("VCP").

It is a good option too. 

Thank you!

Thank you for pointing out the table!

I am using the same PDF file.  

The table does show 4 U(S)ART PINs.  But those PINs might be referring to the STM32F4 chip like @Pavel A.  mentioned. Right now I think only USART1 is available for communication between the board and PC.

Yes, the STM32429I-EVAL board provides only USART1 via the RS232 or IRDA connection.

Other might be possible via the pin headers, but most everything looks to be committed to screens, external memory,etc.

I think this uses the ST-LINK/V2 and predates the V2-1 model with the VCP support. It's a rather old board design, originally from 2013
