4. Setup & Assembly

Follow these steps to assemble your Argon Nanosound ONE Case with your Raspberry Pi 4:

1. Prepare the Case: Carefully remove the screws from the bottom of the Argon Nanosound ONE case to separate the top and bottom sections.
2. Install Thermal Pads: Apply the provided silicon thermal pads to the designated areas on your Raspberry Pi 4's CPU and other heat-generating components. Ensure good contact for optimal heat transfer.
3. Connect Extender Board: Gently connect the Video/Audio PCB Extender to the corresponding ports on your Raspberry Pi 4. This board routes the HDMI and audio signals to the case's external ports.
4. Mount Raspberry Pi 4: Carefully align your Raspberry Pi 4 with the case's internal connectors and mounting points. Ensure the GPIO pins connect correctly to the GPIO - Fan PCB HAT. Secure the Raspberry Pi 4 using the provided screws.
5. Install M.2 SATA SSD (Optional): If using an M.2 SATA SSD, insert it into the M.2 SATA SSD slot on the integrated USB 3.0 board in the bottom section of the case. Secure it with the provided screw. Note: This board is compatible with M.2 SATA SSDs (B-Key or B+M Key) only, not NVMe SSDs.
6. Close the Case: Carefully re-attach the top section of the case, ensuring all ports align correctly. Secure the case with the screws removed in Step 1.
7. Apply Rubber Footings: Attach the rubber footings to the bottom of the case for stability and to prevent scratching surfaces.

5. Operating Instructions

5.1. Software Installation (Operating System)

To get started, you will need to install an operating system on your Raspberry Pi 4. You can install it on a microSD card or directly onto the M.2 SATA SSD if you have installed one. Popular choices include Volumio OS for audio, or Raspberry Pi OS for general use.

For M.2 SSD booting, ensure your Raspberry Pi 4's bootloader is updated to support USB boot. You can then use tools like Raspberry Pi Imager to flash your chosen OS directly to the M.2 SSD (via an external M.2 enclosure connected to your computer, or by booting from microSD first and then flashing to the M.2 SSD).

5.2. Power Button and Fan Control

The Argon Nanosound ONE case features a programmable power button and a 30mm fan for active cooling. To enable advanced power management and fan control features, you need to install the Argon Forty script. This script allows for:

• Safe shutdown and reboot via the power button.
• Software-controllable fan speed based on CPU temperature.
• Configuration of the built-in infrared receiver.

Refer to the official Argon Forty website or the included manual for the latest script installation instructions. Typically, this involves running a command in the terminal of your Raspberry Pi OS.

5.3. Audio Playback and Streaming

With the integrated Hi-Fi DAC, your Raspberry Pi 4 is ready for high-quality audio. Install a compatible audio-focused OS like Volumio, Moode Audio, or RuneAudio. These operating systems provide user-friendly interfaces for managing your music library, streaming from services like Spotify Connect, or integrating with Roon Bridge.

7. Maintenance

To ensure the longevity and optimal performance of your Argon Nanosound ONE Case and Raspberry Pi 4, consider the following maintenance tips:

• Dust Removal: Periodically clean the case and fan (if applicable) to prevent dust buildup, which can hinder cooling efficiency. Use compressed air or a soft brush.
• Thermal Pad Integrity: If you ever disassemble the case, inspect the thermal pads. Replace them if they appear worn or damaged to maintain effective heat transfer.
• Software Updates: Regularly update your Raspberry Pi's operating system and any installed Argon Forty scripts to benefit from performance improvements, bug fixes, and new features.

8. Troubleshooting

If you encounter issues with your Argon Nanosound ONE Case, consider these common troubleshooting steps:

• No Power/Boot:
  • Ensure the USB-C power supply is correctly connected and provides sufficient power (5V, 3A recommended for Raspberry Pi 4).
  • Verify that the Raspberry Pi 4 is correctly seated within the case and all internal connections (extender board, GPIO pins) are secure.
  • Check the power button jumper setting (Default/Always ON) and ensure it matches your desired behavior.
• No Audio Output:
  • Confirm that your audio software (e.g., Volumio) is configured to output audio through the correct DAC device.
  • Ensure your speakers or headphones are properly connected to the audio output jack.
• M.2 SSD Not Detected:
  • Verify the M.2 SSD is correctly inserted and secured in its slot.
  • Ensure the SSD is a SATA M.2 (B-Key or B+M Key) type, as NVMe SSDs are not compatible.
  • Check that your Raspberry Pi 4's bootloader is updated for USB boot if you intend to boot from the SSD.
• Fan Not Working/Overheating:
  • Ensure the Argon Forty fan control script is installed and configured correctly.
  • Check for dust buildup on the fan or heatsink.
  • Verify thermal pads are making good contact with the Raspberry Pi's components.
