STM32 Nucleo F103 pinout and Reference Manual mismatch for Usart1 RX/TX

On Reference Manual RM0008, pag 186, bit 2, Alternate Function I/O Remap, it stats that the only available pairs for Usart 1 RX/TX can be PA9/PA10 or PB6/PB7, but on the pinout image for the same NUCLEO-F103RB the Usart 1 pinout is on PA2/PA3.

Which one of the two is wrong?

Hello,

On the pinout: USART2_TX is on PA2 and USART2_RX is on  PA3.

You can also check the pin definitions in the STM32F103 datasheet.
