I am connecting a nextion screen to my teensy4.1 through UART. It works fine, but I was wondering if for the production environment (the screen will be on a steering wheel, while the teensy is in the dashboard on a custom build pcb, there is about 25 cm between this two devices and the baudrate is 115200) I should implement any protection feature, what I'm most concerned about is EMI as the system will be mounted on a running car. I was thinking about using a TVS diode with a couple of resistors, but I'm not sure if this will have an effect on the signal integrity.
Something like this:
Where screenRX and screenTX are connected to the Teensy serial8 pins and P3 is a connector to the steering wheel display.
