Key Specifications
IIC Character LCM Module is a 20×4 character LCD solution developed for equipment that needs richer text display within a simple module structure. The SJXD2004A-IIC model gives four rows of character output, allowing operators to view menus, values, prompts, and fault information without switching screens too often. It uses a 98.0×60.0×20.0 mm outline, 76.0×25.2 mm viewing area, 3.3V/5.0V drive voltage, AIP31066/ST7066 driver IC, IIC/I2C interface, white LED backlight, STN Negative LCD type, 06:00 viewing direction, -20°C to +70°C working temperature, and -30°C to +80°C storage temperature.
Design Standards
IIC Character LCM Module is designed to support cleaner PCB routing, steady data communication, and practical multi-line information arrangement. The IIC/I2C interface reduces the number of signal lines required by the controller, making it easier to reserve MCU pins for keys, sensors, relays, indicators, or other communication functions. Its STN Negative display mode provides a dark-background viewing effect, while the white LED backlight helps characters remain visible on equipment panels. The module also supports high contrast, low power operation, anti-interference performance, wide-temperature use, multiple color combinations, technical documentation, source code assistance, customization, 1–3 day sample testing, and batch delivery planning.
Applications
IIC Character LCM Module fits products that need to display several groups of text information in a compact control interface. It can present setting menus, process values, device states, alarm codes, service reminders, timer records, operating instructions, and diagnostic feedback across four readable lines. Typical application fields include industrial control equipment, measuring instruments, automation panels, medical devices, access terminals, home appliances, information display systems, consumer electronics, and DIY development boards. Its 20×4 format, IIC connection, STN Negative readability, and white backlight make it suitable for customized panels that require organized text output, efficient integration, and stable long-term display performance.
