Three UARTs on ESP32 with integrated flash

[ArnoKCS]

Hi all,

I have noticed that for units with integrated flash, some pins (*) are used for connecting the embedded flash and are not recommended for other uses.
(*) GPIO16, GPIO17, SD_CMD, SD_CLK, SD_DATA_0 and SD_DATA_1

Datasheets: ESP32-PICO-D4 rev 1.3 and ESP32 rev 2.4

I want to use three UARTs, but to me it seems that UART2 conflicts with the 'reserved' pins for the flash.
pin 25-GPIO16: CS and U2RXD
pin 27-GPIO17: D0 and U2TXD

We use the ESP32-PICO-D4, because of the integrated crystal and flash.
Is it possible to remap UART2 to other GPIO pins?

Thanks in advice,
Arno

Yes, see Setting Communication Pins

Thank you loboris!
We'll check it asap.
