ESP32 Forum

Hey there,

So I'm pretty new to all this ESP stuff and i searched the internet for a while now and didn't find lots of stuff to this topic. 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 are Pin 17,18,19,20,21,22... The schematic of the WT32-SC01Plus board is attached.

Thanks in advance for your help!

You can route the UART to any IO pin you desire (that is, when they're not already occupied by something else). Any of the EXTIO connector IO pins would work fine, for instance.

If you don't need RS485, you can also use the RS485 connector to talk "plain UART".
