It features an 87.0×60.0×19.0 mm module size, 62.0×27.2 mm viewing area, 3.3V/5.0V drive voltage, ST7066/AIP31066 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
LCD Character Display Simulator is built for simplified wiring, stable character response, and convenient simulation-to-hardware testing. The IIC/I2C interface helps reduce pin usage compared with a traditional parallel LCD, making it easier to connect with MCU boards, Arduino-style controllers, teaching platforms, and prototype circuits. Its STN Positive screen presents dark characters on a bright background, while the white LED backlight supports clean indoor readability. The module also supports high contrast, wide-temperature operation, low power consumption, anti-interference performance, multiple color combinations, technical documentation, source code support, customization, 1–3 day sample testing, cost-effective production, and fast batch delivery.
Applications
LCD Character Display Simulator is suitable for projects that need to test or demonstrate four-line character output before final product integration. It can display simulation results, parameter settings, measured data, program feedback, device states, error messages, operating steps, and user instructions in a structured 16×4 format. Common application fields include display simulators, MCU development boards, Arduino projects, training kits, meters, small instruments, industrial control panels, medical devices, home appliances, communication terminals, information display systems, and DIY electronics. Its IIC connection, 16×4 layout, STN Positive readability, and white backlight make it practical for compact display verification and daily equipment interfaces.
