Miuzei Raspberry Pi 3 B+ Case with Fan Cooling and Power Supply Instruction Manual

1. Introduction

This manual provides detailed instructions for the assembly and use of your Miuzei Raspberry Pi 3 B+ Case. This kit is designed to protect your Raspberry Pi board and enhance its cooling performance with an integrated fan and heatsinks, along with a dedicated power supply. Please read these instructions carefully before beginning assembly.

2. Package Contents

Please verify that all the following items are included in your package:

• Miuzei Clear Acrylic Case (9 layers)
• Cooling Fan (30mm, DC 5V)
• Aluminum Heatsinks (3 pieces: 1 large for CPU, 1 medium for LAN, 1 small for RAM)
• 5V 3A Power Supply with ON/OFF Switch
• Set of Screws and Nuts for assembly
• Rubber Feet (4 pieces)
• Installation Instructions (printed manual)

Note: The Raspberry Pi board is not included in this package.

3. Setup & Assembly

Follow these steps to assemble your Miuzei Raspberry Pi 3 B+ Case. For a visual guide, please refer to the official installation video below.

3.1. Prepare Case Layers

1. Carefully remove all 9 acrylic layers from their packaging.
2. Peel off the protective film from both sides of each acrylic layer. This film makes the layers appear cloudy or scratched.

3.2. Install Raspberry Pi Board

3. Identify the bottom layer of the case (Layer 1, typically with screw holes and no large cutouts for ports).
4. Place the Raspberry Pi board onto the designated middle layer (Layer 4 in the diagram). Ensure the board is correctly oriented so that all ports align with the case cutouts. Incorrect orientation will block USB and HDMI cables.

3.3. Attach Heatsinks

5. Peel off the protective backing from the thermal adhesive on each heatsink.
6. Carefully place the heatsinks onto the corresponding chips on the Raspberry Pi board: the largest heatsink on the CPU, the medium heatsink on the LAN chip, and the smallest on the RAM chip. Press firmly for good contact.

3.4. Install Cooling Fan

7. Mount the cooling fan into the designated cutout on the top layer of the case (Layer 9). Ensure the fan's label side is facing downwards, towards the Raspberry Pi board, for optimal airflow.
8. Secure the fan with the provided small screws and nuts.
9. Connect the fan's red wire to a 5V GPIO pin and the black wire to a GND (Ground) GPIO pin on the Raspberry Pi for high-speed operation. For lower speed and quieter operation, connect the red wire to a 3.3V GPIO pin instead. Refer to your Raspberry Pi's GPIO pinout diagram for exact locations.

3.5. Final Case Assembly

10. Stack the remaining acrylic layers in the correct order, starting from the bottom layer with the Raspberry Pi board, and working your way up to the top layer with the fan.
11. Align the screw holes on all layers and insert the longer screws through the entire stack. Secure with nuts on the top.
12. Attach the four rubber feet to the bottom of the assembled case to prevent sliding and provide stability.

4. Operating Instructions

Once assembled, connect the provided 5V 3A power supply to the Micro USB power port on your Raspberry Pi. The power supply features an integrated ON/OFF switch for convenient control of your device.

5. Maintenance

• Keep the case clean by wiping it with a soft, dry cloth. Avoid abrasive cleaners.
• Ensure the cooling fan is free from dust and obstructions to maintain optimal airflow.
• Periodically check all screw connections to ensure they remain secure.

6. Troubleshooting

• Fan Not Spinning: Check that the fan's red and black wires are securely connected to the correct GPIO pins (5V/3.3V and GND). Ensure the Raspberry Pi is powered on.
• Overheating: Verify that the heatsinks are firmly attached to the chips and the fan is operating correctly. Ensure the case layers are properly aligned and not obstructing airflow.
• Ports Blocked: If any ports are obstructed, disassemble the case and re-check the orientation of the Raspberry Pi board and the acrylic layers, especially Layer 3, as shown in the assembly section.
• Power Issues: Ensure the 5V 3A power supply is correctly plugged into a wall outlet and the ON/OFF switch on the cable is in the 'ON' position.
