I am using ESP32-WROVER-IE-N8R8 in my project. I require two set of UART lines , I can use pin 34 and 35 as one set. what are all the pins I can use for UART lines? When I look at the IC datasheet, I found there are three set of UART lines so I look up the I/O MUX...

ESP32 provides three universal asynchronous receivers and transmitter (UART) ports such as UART0, UART1, and UART2 that work at 3.3V TTL level. These three serial interfaces are hardware supported. Each of them exposes 4 pins: RX, TX, RTS and CTS. However, the Arduino IDE only uses RX ...
Description of Change ESP32-P4 has UART default pins only for UART0 and UART1. This PR allows the board definition from pins_arduino.h to define RX2 ... RX4 and TX2 ... TX4 if necessary. It also so...
in ESP32S I have a lot of pins: * GRD, VCC * a lot of GPIO I have connected ESP32 to Lora by those; * Lora GND -> ESP GND * Lora VCC -> ESP VCC 5V * M0, M1 -> GND * Lora RXD and TXD to ESP GPIO 16, 17 in ESP (Tried the opposite as well, do RXD and TXD to ...

So i got a WT32-SC01Plus board with a WT32-S3-Wrover board on there. The WT32-SC01Plus board has 2 UART's used and i need another one on one of the IO Pins i have broken out. Which pins of the J5 connector can i configure to get UART? The related Pins on the ESP itself...
