20x2 OLED Display Module, 20x2 Character Dispaly - REC002002A - Raystar

20x2 OLED Display Module 3.08-inch COB Character Module (RS0010-TX IC)

Model No. REC002002A

The REC002002A is a 3.08-inch 20x2 OLED display module, offering a top-tier 20x2 character OLED solution with COB technology for enhanced reliability. This OLED 20x2 module is available in emitting colors including white, yellow, green, and blue, with a module dimension of 116.0 x 37.0 x 9.8 mm, view area of 85.0 x 18.6 mm, and active area of 77.30 x 11.85 mm. It is powered by the built-in homemade IC RS0010-TX and offers multiple interface options such as 6800, 8080, and SPI for flexible integration in embedded applications.

Designed for durability, the 20x2 character display operates in temperatures from -40°C to +80°C and stores safely from -40°C to +85°C, with a logic supply voltage range of -0.3V to 5.3V. Its energy-efficient, high-contrast design makes it ideal for industrial, medical, and consumer devices requiring low-power, vibrant 20x2 OLED displays.
