4. Assembly Instructions

Follow these steps carefully to assemble your GeeekPi Mini Tower Kit with your Raspberry Pi 4 Model B.

4.1 Prepare the Raspberry Pi

1. Install Thermal Pad: Apply the thermal pad to the CPU of your Raspberry Pi 4.
2. Insert TF Card: For easier installation, insert your TF (Micro SD) card into the Raspberry Pi motherboard before placing it in the case.

Step 3 illustrates fixing the metal bracket of the ICE Tower Cooler with M2.5 screws. Step 4 shows gently pressing the Raspberry Pi and cooler into the case and securing with screws from the bottom.

4.2 Install the ICE Tower Cooler

3. Fix Cooler Bracket: Secure the metal bracket of the low-profile ICE Tower Cooler using the provided M2.5 screws.
4. Mount Raspberry Pi and Cooler: Gently hold down the top of the hot end (cooler) and carefully install the Raspberry Pi and cooler assembly into the main ABS case. Secure them by installing screws from the bottom of the case.

4.3 Secure Raspberry Pi and Connect OLED

5. Fix Raspberry Pi Motherboard: Secure the Raspberry Pi motherboard within the case using M2.5 flat head screws.
6. Connect OLED Cable: Insert the white plug of the OLED screen cable into the side jack of the driver board. Connect the female header to the GPIO pin of the Raspberry Pi. Pay close attention to the direction; the red wire typically indicates the 5V pin. Refer to the GPIO pinout diagram for correct orientation.

4.4 Final Assembly and Power

7. Fasten Acrylic Panels: Attach the transparent acrylic side panels to both sides of the case using the remaining screws.
8. Connect Power: Plug in the QC3.0 power supply to the USB-C power port of the Raspberry Pi.

Important: Ensure all connections are secure and correctly oriented before applying power.

5. Operation and Software Configuration

After physical assembly, software configuration is required to enable the OLED display and RGB lighting features.

5.1 OLED Display Functionality

The 0.96-inch OLED display can show various system information such as the Raspberry Pi's IP address, CPU temperature, memory status, and network card traffic. To enable the OLED display and its RGB ambient light, you must install the necessary drivers.

Note: The OLED display will not show any information until the drivers are installed and enabled. Refer to the official GeeekPi documentation or community resources for specific driver installation instructions.

5.2 ICE Tower Cooler and RGB Fan

The ICE Tower Cooler features a 40mm PWM fan and RGB three-color programmable LED lights. The lights on the cooler will synchronize with the RGB ambient lights on the OLED screen driver board.

Note: The RGB lights on the fan will not illuminate until the corresponding drivers are installed and configured. Consult the official GeeekPi documentation for driver installation and customization options.

6. Maintenance

• Cleaning: Periodically clean the case and fan blades to prevent dust buildup, which can affect cooling performance. Use a soft, dry cloth or compressed air.
• Cable Management: The case includes internal design for cable arrangement. Ensure cables are neatly routed to avoid obstructing airflow or damaging components.
• Firmware/Software Updates: Regularly update your Raspberry Pi's operating system and any installed drivers for the OLED and RGB lighting to ensure optimal performance and security.

7. Troubleshooting

• OLED Display Not Working:
  • Ensure the OLED cable is correctly connected to the GPIO pins (especially the 5V pin).
  • Verify that the necessary drivers for the OLED display have been installed and enabled in your Raspberry Pi's operating system.
• RGB Lights Not Illuminating:
  • Confirm that the RGB lighting drivers are installed and configured.
  • Check all power connections to the OLED driver board and the ICE Tower Cooler fan.
• Poor Heat Dissipation:
  • Ensure the thermal pad is correctly placed between the Raspberry Pi CPU and the ICE Tower Cooler.
  • Verify that the fan is spinning freely and is not obstructed by cables or dust.
  • Check that the cooler is securely mounted to the Raspberry Pi.
• Difficulty with GPIO Expansion:
  • Ensure the GPIO Edge Extension is correctly seated on the Raspberry Pi's GPIO header.
  • If using an external 40-pin parallel cable, ensure it is connected correctly and is not damaged. (Note: This cable is not included).
