Connecting Arduino to MESA 7i95T through serial

Hi all,
Hope you are doing well! I'm trying to implement a status bar using a LED strip (WS2813 RGB LED - Grove) and an Arduino (uno or nano). I wanted to connect the arduino through serial communication directly to the a MESA 7i95T board, to send some string commands to the Arduino to control the LED strip behaviour.

Is it possible to do so? Can I just connect the Arduino to one of the two RS422/485 interfaces of the board? Do I need a specific firmware for the board? In case yes, my setup also includes a MESA 7i87 for reading some sensors.

Thanks,
Best,

Amedeo

You can use smart serial, there are open source project on github

Great thanks! can you please point out to the correct github? I found this but I don't know if it is what you intended:

github.com/fdarling/mesa-smartserial-device-template

yes, i used this 'mesa-smartserial-device-template'
to build my relay card:
github.com/multigcs/SmartSerial-ESP32RelayX8Board

but you need an esp32 or something faster than an uno/nano, because the higher serial baud-rates
