5. Setup Instructions
5.1. Attaching the Acrylic Stands
- Carefully align the acrylic stands with the mounting holes on the back of the display board.
- Insert the provided screws through the stands and into the display's mounting points.
- Tighten the screws securely to ensure the display is stable. Avoid over-tightening.
5.2. Mounting the Raspberry Pi
The display is designed to integrate directly with your Raspberry Pi. Follow these steps:
- Apply the appropriate aluminum heatsinks to your Raspberry Pi's main chips (CPU, RAM, etc.) if using a Raspberry Pi 4. For Raspberry Pi 5, consider using the included Armor Lite and heatsink fan.
- Position your Raspberry Pi board onto the designated mounting area on the back of the display. Ensure the Pogo Pins (for power and touch) align correctly with the Raspberry Pi's GPIO pins.
- Use the provided converter connectors (HDMI and USB) to bridge the connections between the Raspberry Pi and the display's ports. These connectors are designed to create a compact, cable-free connection.
- Secure the Raspberry Pi to the display using the provided screws and standoffs.

5.3. Connecting Power and HDMI
- Connect the full-size HDMI cable from your Raspberry Pi's HDMI output to the HDMI IN port on the display. If using the converter connector, this step is integrated with Pi mounting.
- Connect the USB to USB-C cable from your Raspberry Pi's USB port to the 'Touch & Power' USB-C port on the display. This enables touch functionality.
- Plug the included USB-C power supply into the 'Power IN' port on the display, then connect it to a wall outlet.
5.4. Software Configuration (Raspberry Pi OS)
For optimal performance and touch functionality, ensure your Raspberry Pi OS is up to date. No specific drivers are typically required for the display or touch screen, as it is designed for driver-free operation. However, you may need to configure screen resolution or rotation within your Raspberry Pi OS settings if not automatically detected.
6. Operating Instructions
6.1. Power On/Off
Locate the 'Volume/Backlight/On/Off Switch' on the side of the display. Toggle this switch to power the display on or off.
6.2. Touchscreen Usage
The display features a capacitive touch screen. Once connected via the USB cable to your Raspberry Pi, it should function as a standard touch input device. Use your finger for navigation and interaction with the operating system.
6.3. On-Screen Display (OSD) Menu
The display includes an OSD menu for advanced settings. Use the toggle switches on the side of the display to navigate and adjust settings such as:
- Brightness: Adjust the screen's luminosity.
- Volume: Control the audio output level of the built-in speakers.
- Contrast: Modify the difference between light and dark areas.
- Color Temperature: Adjust the color balance of the display.
- Input Selection: Switch between available video inputs (if applicable).
6.4. Audio Output
The built-in dual speakers receive audio exclusively from the HDMI output of your Raspberry Pi. Ensure your Raspberry Pi's audio output is directed to HDMI for sound to play through the display's speakers.
6.5. HAT Compatibility
This display is designed to be compatible with various Raspberry Pi ADD-ON HATs, including Innomaker DAC/DAC PRO/AMP/AMP PRO. When integrating a HAT, ensure proper alignment and connection to the Raspberry Pi's GPIO pins, taking care not to obstruct the display's mounting or connections.

7. Maintenance
7.1. Cleaning the Display
To clean the screen, gently wipe it with a soft, lint-free cloth. For stubborn smudges, slightly dampen the cloth with water or a screen-safe cleaning solution. Avoid using harsh chemicals, abrasive materials, or excessive moisture.
7.2. General Care
Keep the display away from direct sunlight, extreme temperatures, and high humidity. Avoid dropping the device or exposing it to strong impacts. When not in use for extended periods, store it in a dry, dust-free environment.
8. Troubleshooting
8.1. No Display Output
- Ensure the display is powered on and the power supply is securely connected to a working outlet.
- Verify that the HDMI cable is correctly connected between the Raspberry Pi and the display.
- Check the input source setting in the OSD menu to ensure it is set to HDMI.
- Confirm your Raspberry Pi is powered on and outputting video.
8.2. Touch Screen Not Responding
- Ensure the USB to USB-C cable is securely connected from your Raspberry Pi to the display's 'Touch & Power' port.
- Verify that your Raspberry Pi's operating system recognizes the touch input device.
- Restart both the Raspberry Pi and the display.
8.3. No Audio from Speakers
- Confirm that the Raspberry Pi's audio output is configured to use HDMI.
- Check the volume level on the display using the toggle switch or OSD menu.
- Ensure the HDMI cable is fully seated.
8.4. Unstable Acrylic Stands
- Ensure all screws securing the stands are tightened firmly.
- If the stands still feel loose, consider adding small nylon washers between the screw head and the stand to provide additional compression.
8.5. Micro HDMI Adapter Issues
- If you experience intermittent display issues when using the provided micro HDMI adapter, try using a direct mini HDMI to HDMI cable (if your Raspberry Pi model supports it) or a different adapter to rule out the adapter as the cause.
