Displays
SH1106
OLED controller common in 1.3-inch monochrome displays and SSD1306-like modules.
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.
Technical Specifications
Common Use Cases
- Maker prototypes
- Low-cost modules
- Educational hardware
Known Issues
- Breakout boards may use different pin labels or regulator choices
- Clone modules can differ from the original datasheet part
Interfaces and Library Support
Every field is meant to be source-backed. Corrections should include a datasheet URL, vendor page, module photo, or reproducible library test.

Pinout Table
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
Power the module from a rail that matches the breakout board, not just the bare IC.
Connect ground between the controller, sensor/module, and external power supply.
Use pull-ups appropriate for the board voltage; many modules already include them.
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)Recommended Development Boards
Good match for SPI/I2C displays and enough memory for UI experiments.
Simple 5V classroom baseline when the display module includes level shifting.
Useful MicroPython test target for SPI and I2C display drivers.
