      Hello, I’m trying uart communication between STWI035WT-01 and STM32F446RE.

      And I’d like to change the UART port level of LCD. (I don’t want to apply TTL to RS232 converter)

      Is it right to weld two area(①,②) of TTL? Do I have to remove all(③~⑥) 0Ω resistor in the area of 232?

      Please check and reply.

      Thank you for your answer.

      I solved the problem, thanks to master’s check.

      For whom this way can help to solve problem,
      ————————————————
      I found the ttl/r232 area inside of the lcd cover. (In case of STWI-035, you need to take off cover, and be careful not to break the wire)

      Solderd two ttl areas and removed four rs232 resistors.
      ————————————————
      thank you.
