If you don't have an FW for 3D printing for this screen, then the display will be just a piece of iron. You have to buy a display for a...

The display communicates with Marlin via the serial port. If your display has the necessary FW, just define serial port 2 in Marlin #define SERIAL_PORT 2 or #define SERIAL_PORT_2 2

I would use an external connector and connect to the motherboard. What's your version? Send a photo of the damage.

How did you go about creating FW? Did you download Marlin and edit the configuration files? A lot of people make the mistake of downloading a new Marlin and copying...

Try using the platform for compilation STM32F103RC_btt_maple

Theoretically, it would be possible. You need to find a free pin that supports analog input (voltage measurement), connect a resistor divider with a capacitor and define a pin in...

Measuring temperature is not the same as connecting a limit switch. Temperature measurement is performed by measuring the voltage on a resistive divider that contains a thermistor. You also can't...

Caution the processor has 3.3V logic and some pins are sensitive to higher voltages and can be destroyed by 5V voltages!

Probably a damaged mosfet that spins a fan. A frequent defect .... https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/issues/238
