Hi @Seeed_Seraphina ,
Thank you for the answer. Unfortunately, I can not find the information about the pins in the description of the ReServer (28-pin Arduino Pinout, 9-pin COM Pinnoutx2, 9-pin USB2.0 Pinout, 9-Pin Front panel Pinout, see https://files.seeedstudio.com/wiki/reServer/wiki/reServer%20mainboard%20.png). Is there anywhere a description how to use those with this x68i5 board ?
Thank you
