Hi All,
I search for STM32 MCU discovery kit which meets the following conditions.
・It have a 4-inch or larger LCD screen.
・It have 10 or more GPIO ports that user can use freely.
・It have 2 or more UART ports that user can use freely.
STM32U5G9J-DK2 have 16 GPIO ports, but only have 1 UART according to user manual.
Is there anything else that meets the above conditions.
Thanks in advance.

Not sure
Most have pins all well used up.
There's perhaps a couple of the F7 and H7 with screens, and Arduino Shield headers exposing GPIO / UART
Perhaps some NUCLEO-144 you can mount a display too? Riverdi had a board as I recall.
Other than that you might need to look up some third-party boards

The STM32H747I-DISCO has all of those.
PC6/PC7 are free for USART6
PD5/PD6 are free for USART2
