Key Specifications
I2C Characters LCD is a 20×4 character display module built for equipment that needs more visible text content on one compact screen. The SJXD2004A-IIC model provides four display rows, allowing users to view menus, values, alerts, and operation notes with better spacing. 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, yellow 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 Characters LCD is developed for clear multi-row character presentation, efficient controller connection, and stable embedded operation. The IIC/I2C interface helps reduce signal-line usage, making the module easier to integrate into compact PCB designs where extra MCU pins are needed for keys, sensors, relays, or communication ports. The STN Positive display mode creates a light-background viewing style, while the yellow LED backlight gives the interface a distinctive visual appearance. The module also supports high contrast, low power consumption, anti-interference performance, multiple color options, technical documentation, source code support, customization service, 1–3 day sample testing, and fast batch production planning.
Applications
I2C Characters LCD is suitable for products that need organized four-line information display without using a complex graphic screen. It can present setting pages, measurement values, alarm records, system feedback, timer data, operating steps, service reminders, and diagnostic messages in a readable character format. Common application fields include measuring instruments, industrial controllers, automation panels, medical devices, access terminals, household appliances, consumer electronics, information display systems, and DIY development boards. Its 20×4 layout, IIC connection, STN Positive readability, and yellow backlight make it practical for compact interfaces requiring richer text output and smooth hardware integration.
