To connect the Joy-IT Joypi Expansion Kit to your Raspberry Pi, follow these steps as outlined in the user guide:

1. **Assembly:** First, xxxx the spacers to the port doubler. Your Raspberry Pi should already be screwed into the JoyPi. Plug the port doubler onto the Raspberry Pi. Connect the GPIO strip of the JoyPi to the GPIO strip of the port doubler using the supplied cable.

2. **Installation:** Install the necessary libraries for the ADC and the pressure and temperature sensor. If you are using your own image, you can install the libraries using the provided commands. Make sure to enable I2C by entering the command `sudo raspi-config` and enabling I2C under Interfacing Options.

3. **Port-Doubler:** The Port-Doubler has 4 GPIO strips that allow the use of external sensors with the JoyPi. The pinout of each GPIO strip matches that of the Raspberry Pi, as detailed in the manual.

4. **Analog-Digital Converter (ADC):** The ADC converts analog voltage into a digital signal. Connect the ADC to the Raspberry Pi following the pin assignment provided in the manual. Run the code example to output voltages from the input channels.

5. **Sliding Potentiometer or Rotary Potentiometer:** Connect either the sliding or rotary potentiometer to the ADC as per the pin assignment provided in the manual. Run the code example to output voltages from the potentiometer.

6. **Magnetic Sensor:** Connect the magnetic sensor to the ADC following the pin assignment provided. Run the code example to output voltages and check the limit value.

7. **Joystick:** Connect the joystick to the ADC using the pin assignment provided. Run the code example to output voltages for the X and Y axis and detect joystick press.

8. **Pressure and Temperature Sensor:** Connect the BMP280 sensor to the Raspberry Pi following the pin assignment provided. Run the code example to output temperature and air pressure readings.

By following these steps and referring to the detailed instructions in the user guide, you should be able to successfully connect and utilize the Joy-IT Joypi Expansion Kit with your Raspberry Pi.
