Unable to init uart with micropython & ttl to rs485

I'm using a board with the next GPIO as the image: enter image description here Also im ussing a TTL to RS-485 module at 5V with chipset MAX485.

ESP32 MAX485
RX DI
TX RO
15 DE & RE

When I add the line to init uart, the board doesn't reply more.

from machine import UART

print("hello")
uart = UART(1,baudrate=9600, bits=8, parity=None, stop=1, rx=3,tx=1)
print("bye")

As anyone know about what I'm doing bad?

many thanks

Seems that board shares the tx+rx pins 1&3 with the usb debug, cause of that i lost my com with the esp32 and is the cause of "no response"
