What it is
The 1.3" I2C Blue OLED Display Module 4-Pin SH1106 is a compact 128x64 monochrome blue OLED for sensor data, menus, clocks, status readouts, and simple UI elements. It uses the SH1106 driver and a 4-pin I2C connection for straightforward use with Arduino, Raspberry Pi, ESP32, and other I2C-capable boards; this version is I2C rather than SPI or UART, and its 1.3-inch screen is easier to read than many 0.96-inch OLEDs.
Pins
- VCC – Power input. Check the board markings or listing photos for the correct voltage.
- GND – Ground.
- SDA – I2C data line.
- SCL – I2C clock line.

Frequently Asked Questions
How do I wire the 1.3-inch SH1106 OLED to an Arduino, Raspberry Pi, or ESP32?
Use the 4-pin I2C pinout: VCC, GND, SDA, and SCL. Connect SDA and SCL to your board's I2C pins, then confirm the required supply voltage from the module markings or listing photos.
Is this OLED display I2C, SPI, or UART?
This module is the 4-pin I2C version. The product description does not list SPI or UART support for this board.
Does this SH1106 OLED work with Raspberry Pi and ESP32 libraries?
Yes. It is intended for platforms with I2C support such as Raspberry Pi and ESP32, using software or libraries that support SH1106-based 128x64 OLED displays.
What can I display on a 128x64 blue OLED screen like this?
It is a good fit for sensor readings, menus, clocks, status text, and simple graphics in robotics, home automation dashboards, and handheld DIY devices.
Where can I find the pinout or datasheet info for this OLED module?
Start with the board silkscreen and listing photos for the exact pinout, then check SH1106 datasheet or library documentation for controller behavior. Board-level electrical details can vary by module revision.
