It features a 116.0×37.0×20.0 mm module size, 83.0×18.6 mm viewing area, 3.3V/5.0V drive voltage, ST7066/AIP31066 driver IC, IIC/I2C interface, white LED backlight, FSTN Positive LCD type, 06:00 viewing direction, -20°C to +70°C working temperature, and -30°C to +80°C storage temperature.
Design Standards
Linux LCD Character Display is developed for stable embedded communication, reduced wiring effort, and practical software-controlled text presentation. The IIC/I2C interface helps reduce signal-line demand, making it easier to connect with Linux development boards, single-board computers, industrial controllers, and MCU systems. Its FSTN Positive display structure supports sharp character definition on a clean light background, while the white LED backlight helps maintain readable output in equipment panels. The module also supports high contrast, low power consumption, anti-interference performance, multiple color combinations, complete technical information, source code support, customization, 1–3 day sample testing, and fast batch delivery planning.
Applications
Linux LCD Character Display is suitable for embedded products that need direct status feedback without using a large graphic screen. It can show boot information, IP addresses, sensor readings, device states, menu options, warning prompts, debugging messages, and operation guidance in a two-line format. Typical application fields include Linux control terminals, industrial devices, meters, automation equipment, medical instruments, home appliances, consumer electronics, information display systems, and DIY development boards. Its 20×2 layout, I2C connection, FSTN Positive readability, and white backlight make it practical for compact systems requiring reliable character output and easier hardware integration.
