User Guide / How to Use

• Wiring I2C pins connect VCC to 3.3V or 5V as supported by your board, GND to ground, SCL to the microcontroller clock pin, and SDA to the data pin
• Arduino example use U8g2 library, install via Library Manager, choose a SH1106 I2C constructor, and set the I2C address to 0x3C if applicable
• Raspberry Pi setup enable I2C in raspi-config, install Python libraries such as luma.oled or Adafruit Blinka and confirm bus with i2cdetect
• Contrast and brightness adjust using library functions to optimize for ambient light
• Font and graphics render text, bitmaps, icons, and progress bars with library API calls for quick UI creation
• Performance tips buffer updates efficiently and avoid redrawing the entire screen when only small regions change
• Troubleshooting verify wiring, ensure SH1106 driver selection, and confirm I2C address by inspecting the solder jumpers on the PCB

Frequently Asked Questions (FAQs)

• Q: Is this module compatible with SSD1306 libraries
  A: Many SSD1306-only libraries will not work correctly. Use libraries that explicitly support SH1106 such as U8g2 or luma.oled.
• Q: What is the default I2C address
  A: Most 1.3 inch SH1106 modules ship with 0x3C. Check the board silkscreen or jumpers to confirm or change it.
• Q: Can I power it from a 5V Arduino
  A: Yes. The module accepts 3.3V to 5V and works with 5V logic, making it plug friendly with Arduino Uno R3 and Mega.
• Q: Does it need a backlight pin
  A: No. OLED pixels are self-emissive, so there is no backlight line to control.
• Q: Which libraries do you recommend for Arduino
  A: U8g2 is a robust choice with wide font support and SH1106 compatibility. It is recommended by Bigyan Project for reliability.
• Q: Will it work with ESP32 and ESP8266
  A: Yes. Connect SDA and SCL to the respective I2C pins and use a library that supports SH1106.
• Q: How do I display bitmaps or logos
  A: Convert images to monochrome bitmaps and use your library’s bitmap drawing function with correct width and height.

Challenges and Considerations

• SH1106 vs SSD1306 differences require selecting the correct driver in code
• Monochrome output supports only one color on or off per pixel
• Small 1.3 inch screen area limits the amount of text per page
• I2C bus length and noise can cause communication errors if wires are too long
• Brightness and lifetime higher brightness may reduce OLED longevity over time

Compatibility

• Arduino Uno R3, Mega 2560, Nano, Leonardo with I2C
• Raspberry Pi Zero, 3, 4, 5 with I2C enabled
