Thank you, Alain!

Regarding the Terrans EXOS2 Lite version, I conducted some experiments.

I tested updating the firmware via the ESP32 download tool using Lite.bin just to ensure that I have a recovery plan. I disassembled the Lite version and found out that the drivers are TMC2225S. I made some changes in Config.h and updated the firmware via Arduino IDE. The device seems to be working as expected, but I will conduct some tests on stars before confirming.

These changes need to be made in the config for Lite - EQ5/CG5 mounts:

#define AXIS1_DRIVER_MODEL TMC2225S
#define AXIS1_STEPS_PER_DEGREE 7680
#define AXIS1_REVERSE OFF
#define AXIS1_DRIVER_MICROSTEPS 32

#define AXIS2_DRIVER_MODEL TMC2225S
#define AXIS2_STEPS_PER_DEGREE 7680
#define AXIS2_REVERSE OFF
#define AXIS2_DRIVER_MICROSTEPS 32

#define AXIS3_DRIVER_MODEL OFF
#define AXIS4_DRIVER_MODEL OFF
#define FEATURE1_PURPOSE OFF"

Best regards,
Spas
