5. Setup
5.1 Unpacking and Inspection
Carefully remove the OLED display module from its packaging. Inspect the module for any visible damage. If any damage is found, do not proceed with installation and contact customer support.
5.2 Connection
The module features a 24-pin flexible printed circuit (FPC) connector. Ensure proper alignment and secure connection to your host device or development board. The module supports both SPI and IIC communication protocols. Refer to your host device's documentation for specific wiring diagrams for either SPI or IIC interface.

5.3 Power Supply
Connect the module to a stable power supply according to the specifications of your host device. Ensure the voltage and current provided are within the module's operating range to prevent damage.
Important Note: The screen is fragile. Handle the module with extreme care during installation to avoid bending, twisting, or applying excessive pressure to the display area or the FPC.
6. Operating Instructions
6.1 Initializing the Display
After connecting the module to your host device, you will need to initialize the display using appropriate software libraries or code. This typically involves sending a sequence of commands to configure the display controller (SSD1305 or compatible) for resolution, contrast, and display mode.
6.2 Displaying Content
Once initialized, you can send pixel data to the display buffer via the chosen SPI or IIC interface. The module's self-illuminating pixels will then render the content, providing a bright and clear image. Consult the datasheet of the display controller (e.g., SSD1305) for detailed command sets and data transfer protocols.

7. Maintenance
7.1 Handling and Storage
Always handle the OLED module by its edges or the FPC, avoiding direct contact with the display surface. Store the module in its original anti-static packaging or a similar protective enclosure when not in use. Avoid exposing the module to extreme temperatures, high humidity, or direct sunlight.
7.2 Cleaning
To clean the display surface, gently wipe it with a soft, dry, lint-free cloth. Do not use abrasive cleaners, solvents, or excessive force, as this can damage the display or its protective layers.
8. Troubleshooting
8.1 No Display Output
- Check Power: Ensure the module is receiving adequate and stable power within its specified voltage range.
- Verify Connections: Confirm that all 24 pins of the FPC are securely and correctly connected to the host device.
- Software Initialization: Ensure your code properly initializes the OLED controller and sends the necessary commands to turn on the display.
- Interface Selection: Double-check that your software is configured for the correct communication interface (SPI or IIC) matching your hardware connection.
8.2 Dim or Inconsistent Display
- Contrast Settings: Adjust the contrast settings in your display initialization code.
- Power Supply: Fluctuations or insufficient power can lead to dim displays. Ensure a stable power source.
- Data Integrity: Verify that data is being sent correctly and without corruption over the SPI/IIC bus.
8.3 Incorrect or Garbled Display
- Data Format: Ensure the pixel data format and addressing mode (e.g., page addressing, column addressing) match the display controller's requirements.
- Clock Speed: For SPI/IIC, verify that the clock speed is within the acceptable range for the OLED module.
- Pin Assignments: Confirm that the data, clock, and control pins are correctly assigned in your hardware and software.
9. Safety Information
- Fragile Component: The OLED display is a delicate electronic component. Avoid dropping, bending, or applying pressure to the screen.
- Electrostatic Discharge (ESD): Always use appropriate ESD precautions (e.g., anti-static wrist strap, mat) when handling the module to prevent damage from static electricity.
- Power Supply: Use only recommended power supply voltages. Exceeding the maximum voltage can permanently damage the module.
- Environmental Conditions: Do not expose the module to liquids, extreme temperatures, or corrosive environments.
- Disassembly: Do not attempt to disassemble the module. This may void any potential warranty and can cause damage.
