COG OLED, OLED COG Character 1.23-inch 16x2 - REX001602B - Raystar

COG OLED Display Module with PCB Character 1.23-inch 16x2 (RS0012 IC)

Model No. REX001602B

The REX001602B is a 1.23-inch 16x2 COG+PCB Character OLED display module, designed as a reliable solution for applications that require compact and clear text output. With a module size of 53.0 × 20.0 × 7.6 mm and an active area of 30.69 × 5.94 mm, it delivers excellent readability in limited spaces. This module is powered by the built-in homemade RS0012 IC, ensuring stable operation and broad compatibility. Users can choose from multiple interface options including 6800, 8080, and SPI, making this COG OLED display easy to integrate across different systems.

Available in white and yellow emitting colors, the REX001602B offers a wide operating temperature range (-40°C to +80°C) and low-power 3.3V logic operation, providing consistent performance in both industrial and commercial environments. As an OLED COG module, it features an ultra-thin design, high reliability, and simplified assembly by directly mounting the driver IC on the glass—ideal for projects that require durability and efficiency.
