Supporting both IIC and 4-wire SPI communication, it combines a passive matrix design with stable optical performance, wide viewing angles, and extended temperature tolerance, making it well-suited for industrial, consumer, and portable electronic systems.

Mechanical Specifications

General Description of the Module

This OLED display module is engineered around a 2.42-inch panel, offering a graphical resolution of 128×64 pixels. Its passive matrix driving scheme ensures low power consumption while maintaining sufficient brightness and contrast for clear visual output. The module supports multiple monochrome emission colors, including white, yellow, and green, allowing flexible adaptation to different product aesthetics and usage scenarios.

The overall structure is optimized for compact integration. With an outline dimension of 72.0 × 43.0 × 5.9 mm, it fits efficiently into space-constrained designs without compromising display readability.

Core Technical Characteristics

Display Performance

The effective display area of 55.01 × 27.49 mm is carefully matched with a pixel pitch of 0.43 mm, resulting in uniform pixel distribution and stable image rendering. Each pixel measures approximately 0.39 × 0.39 mm, contributing to a balanced combination of clarity and luminance.

The module supports a 1/64 duty driving method, ensuring consistent brightness across the entire panel. In addition, the “all viewing direction” feature enhances usability by maintaining visual consistency regardless of the observer’s angle.

Interface and Control Logic

At the heart of the module lies the SSD1309 driver IC, a mature and widely adopted controller in OLED applications. It provides flexible communication options, including IIC and 4-wire SPI interfaces.

The 7-pin configuration simplifies electrical connections while preserving essential control and data pathways. This streamlined interface design reduces system complexity and supports rapid integration with mainstream microcontrollers and embedded platforms.

Mechanical and Environmental Reliability

The module is designed to operate reliably across a wide temperature range, from -40°C to 80°C, with storage capability extending up to 85°C. Such robustness makes it suitable for demanding environments, including industrial control systems and outdoor devices.

Its mechanical construction ensures durability while maintaining a lightweight and compact profile, which is advantageous in portable and handheld equipment.
