Is it possible to control that M4 board using Klipper? I tried connecting my RPI running Klipper to my M4. I configured the Serial port and baud rates. But Klipper would not connect. I tried pronterface and it could connect. So its not a serial setting. But I have not used klipper before so highly likely I just missed something.

Seems the klipper have not support the MCU of ESP32 which is used on M4.
