ESP32 input only used as UART RX

Postby skteh76 » Tue May 05, 2020 1:54 pm

Hi,

Recently I'm working on a project using ESP32-WROVER-B module.
I'm running out I/O as included the RMII ethernet phy.
I'm wondering if those input only GPIO (IO34 and above in ESP32) can be configured as UART RX pin.
Hope someone can enlighten me.

Thank you,
