Hi All,
Good day!
I am using WROVER module in my design and not sure if i can brought out UART1 on any of the GPIO pads using GPIO Matrix.
I am planning to configure as follows.I read through some topics on this forum and other github pages.
However, i would like to double confirm before releasing the PCB gerber for fabrication.
IO15 - UART1_TXD -> Output
IO2 - UART1_RXD -> Input
IO4 - UART1_RTS -> Input
IO21 - UART1_CTS -> Output
Thanks in advance!
Regards,
VM

Yes, you can, but keep in mind that there are bootstrap pins (GPIO15/2 are bootstrap pins iirc), you want to make sure that they'll be the proper levels on bootup.

Hi @ESP_Sprite,
Thanks for your quick response.
I swapped some signals and moved the UART lines to the different pads as follows,
IO27 - UART1_TXD -> Output
IO14 - UART1_RXD -> Input
IO12 - UART1_RTS -> Input
IO13 - UART1_CTS -> Output
