4. Operating Instructions

4.1. UPS Plus Hat

The UPS Plus Hat provides an uninterruptible power supply for your Raspberry Pi. When connected to an external power source, it charges the installed 18650 batteries while simultaneously powering the Raspberry Pi. In the event of an external power failure, the UPS Plus Hat automatically switches to battery power, ensuring continuous operation of your system. It can also power the Raspberry Pi via Pogo Pins, conserving GPIO resources.

4.2. ICE Tower Cooler

The ICE Tower Cooler is designed to maintain optimal operating temperatures for your Raspberry Pi 4. It features a tower structure with a 5mm copper tube, multi-layer heat sinks, and a 7-blade PWM RGB fan. This cooling system is highly effective, capable of reducing the Raspberry Pi's temperature significantly, even under overclocking conditions. The fan's PWM (Pulse Width Modulation) functionality allows for dynamic speed control, and its RGB lighting provides visual feedback.

4.3. 0.96 inch OLED Display

The 0.96 inch OLED screen, pre-mounted on the case, can display various system information for your Raspberry Pi or UPS Plus. Through programming, you can customize it to show data such as the Raspberry Pi's IP address, CPU temperature, disk utilization, CPU load, memory status, network card traffic, and other relevant system metrics.

5. Software Configuration

To fully utilize the features of the ICE Tower Cooler, UPS Plus Hat, and OLED Display, specific software configuration is required. This typically involves installing drivers and scripts on your Raspberry Pi operating system.

• OLED Display: Scripts are needed to fetch and display system information on the OLED screen.
• ICE Tower Cooler Fan: Configuration may be required to control the PWM RGB fan speed based on CPU temperature.
• UPS Plus Hat: Software can monitor battery status, charge levels, and manage power-related events.

For detailed software installation and configuration guides, please refer to the official GeeekPi Wiki: wiki.52pi.com/index.php?title=ZP-0129. This resource provides up-to-date instructions and necessary scripts.

6. Maintenance

Proper maintenance ensures the longevity and optimal performance of your GeeekPi Mini Tower Case components:

• Cleaning: Periodically clean the ICE Tower Cooler fan and heatsinks to prevent dust accumulation, which can impede cooling efficiency. Use compressed air or a soft brush.
• Battery Care (UPS Plus): If using 18650 batteries, ensure they are of good quality and correctly inserted. Avoid over-discharging or over-charging. If the system will be stored for an extended period, it is advisable to remove the batteries.
• Case: Wipe the ABS case and acrylic panels with a soft, dry cloth. Avoid harsh chemicals that may damage the material.

7. Troubleshooting

This section addresses common issues you might encounter:

• OLED Display Not Working:
  • Check the cable connection between the OLED and the driver board, and the driver board to the Raspberry Pi GPIO.
  • Ensure the necessary software drivers and scripts for the OLED are correctly installed and running on your Raspberry Pi. Refer to the GeeekPi Wiki for guidance.
• ICE Tower Cooler Fan Not Spinning:
  • Verify the fan cable is securely connected to the OLED driver board.
  • Confirm that the fan control software or script is properly configured and running.
  • Check for any physical obstructions preventing the fan blades from spinning.
• UPS Plus Hat Not Providing Backup Power:
  • Ensure 18650 batteries are correctly inserted with the right polarity and are charged.
  • Check the connection of the UPS Plus Hat to the Raspberry Pi, especially the pogo pins.
  • Verify that the external power supply is functioning correctly.
• System Overheating:
  • Ensure the ICE Tower Cooler fan is spinning and free of dust.
  • Confirm the heat dissipation sticker is properly applied to the Raspberry Pi CPU.
  • Check that the fan control software is actively managing fan speed based on temperature.
