SH1106

OLED controller common in 1.3-inch monochrome displays and SSD1306-like modules.

China-madeSino WealthActiveModerate

Best For

Projects needing OLED and I2C with a commonly available displays part.

Avoid If

You need production-grade certainty without checking the exact module vendor, pinout, and library maintenance status.

Quick Decision Notes

SH1106 is indexed as a displays part from Sino Wealth. ChipScout tracks it by practical maker-facing dimensions: interfaces, library readiness, estimated price, field-level sources, and whether the page is strong enough for selection rather than only lookup.

Pinout Table

VCC3.3VPower the module from a rail that matches the breakout board, not just the bare IC.
GNDCommon groundConnect ground between the controller, sensor/module, and external power supply.
SDAMCU I2C dataUse pull-ups appropriate for the board voltage; many modules already include them.
SCLMCU I2C clockKeep wiring short for breadboard prototypes and lower bus speed if unstable.
SCKMCU SPI clockShare with other SPI devices when chip select lines are separate.
MOSIMCU SPI data outRequired for most displays, radios, and writable devices.
MISOMCU SPI data inMay be optional for write-only displays.
CSAny free GPIOUse one chip-select pin per SPI peripheral.

Pinout is not yet source-verified. Use the table as an integration checklist, then confirm exact pins against the module vendor page before wiring hardware.

Common Wiring

VCC

Power the module from a rail that matches the breakout board, not just the bare IC.

GND

Connect ground between the controller, sensor/module, and external power supply.

SDA

Use pull-ups appropriate for the board voltage; many modules already include them.

SCL

Keep wiring short for breadboard prototypes and lower bus speed if unstable.

Arduino Example

#include <Wire.h>

void setup() {
  Serial.begin(115200);
  Wire.begin();
  Serial.println("SH1106 I2C wiring smoke test");
}

void loop() {
  // Replace this with the maintained SH1106 library call.
  Serial.println("Check SH1106 on the I2C bus, then read a sample.");
  delay(1000);
}

MicroPython Example

from machine import Pin, I2C
import time

i2c = I2C(0, scl=Pin(1), sda=Pin(0), freq=100000)
print("SH1106 I2C devices:", i2c.scan())

while True:
    # Replace with the maintained SH1106 driver call.
    print("read SH1106 sample")
    time.sleep(1)
