Additional UART on ESP32 WROOM32

[mohbello]

Hi All,

I have an ESP32-WROOM32D that will be controlling GPS, LTE, and SD CARD. According to the documentation, the module has 3 UARTs, with One connected to the Flash.

What would you recommend to extend the UARTs to have a total of 4? So that every module will have it's own connection to the ESP32 and I can program without having to switch between between UART?

is There any link or similar examples available that someone can share ?

Thanks, and Have a great day!

SD card uses spi/sdio and flash uses spi not uart. So you have 2 spi, 1 sdio, and 3 uart.
