Summary

M5Stack Mini OLED Unit is a compact monochrome display module based on the SSD1306/SSD1315 controller with I2C interface. It allows rendering of text, images, and graphics with configurable orientation and contrast.

Description

The M5Stack Mini OLED Unit provides a small but versatile OLED screen using I2C communication. It supports adjustable contrast, mirroring, orientation, and multiple rendering elements such as text, images, and graphics. This unit is ideal for compact UIs, sensor readouts, and status displays in M5Stack-based projects.
