Key Specifications
I2C Dot Matrix is a 20×4 character LCD module created for equipment that needs more visible information in a compact dot-matrix layout. The SJXD2004A-IIC model provides four display rows, allowing menus, numbers, prompts, and system notes to appear with clearer separation. It features a 98.0×60.0×20.0 mm module size, 76.0×25.2 mm viewing area, 3.3V/5.0V drive voltage, AIP31066/ST7066 driver IC, IIC/I2C interface, white LED backlight, STN Positive LCD type, 06:00 viewing direction, -20°C to +70°C working temperature, and -30°C to +80°C storage temperature.
Design Standards
I2C Dot Matrix is designed to improve information arrangement while keeping controller connection simple. The IIC/I2C interface reduces the number of required signal lines, helping engineers save MCU pins and simplify PCB routing for compact control boards. Its dot-matrix character structure supports letters, numbers, and basic symbols across four readable rows, while the STN Positive screen and white LED backlight provide a clean light-background viewing effect. The module also supports high contrast, low power consumption, anti-interference performance, multiple color combinations, complete technical information, source code assistance, customization, 1–3 day sample testing, and fast batch delivery planning.
Applications
I2C Dot Matrix is suitable for products that need multi-line text display without using a complex graphic LCD. It can show setup menus, running values, warning notes, machine states, operation steps, timer data, maintenance reminders, and diagnostic messages on one screen. Typical application areas include meters, equipment control panels, information display systems, industrial controllers, medical devices, household appliances, consumer electronics, access terminals, and DIY development boards. Its 20×4 layout, I2C communication, STN Positive readability, and white backlight make it practical for compact interfaces requiring organized text output and efficient hardware integration.
