Key Specifications

LCD 1602 I2C 3.3 V is a 16x2 character display module designed for low-voltage controller projects and compact electronic equipment. The JXD1602A-IIC model features an 80.0×36.0×17.5mm module outline and a 64.5×14.0mm viewing area, giving developers two rows for values, labels, prompts, and short messages. It supports 3.3V/5.0V drive voltage, ST7066/AIP31066 controller IC options, IIC/I2C communication, white LED backlight, and STN positive display mode. Its operating temperature range is -20°C to +70°C, with storage tolerance from -30°C to +80°C.

Design Standards

LCD 1602 I2C 3.3 V is built for cleaner wiring and easier integration with Arduino, Raspberry Pi, ESP, and other microcontroller systems. The I2C interface reduces the number of signal connections, helping engineers reserve more pins for sensors, buttons, communication modules, or control circuits. The white backlight supports clear viewing in equipment panels, while the 06:00 viewing direction suits front-mounted installation. The module also offers low power use, high contrast, anti-interference performance, and customization options for backlight color, display layout, housing fit, and project-specific appearance.

Applications

LCD 1602 I2C 3.3 V is suitable for products that need stable two-line text display without the cost or complexity of a graphic screen. It can show temperature, voltage, humidity, timer data, menu items, alarm notices, connection status, and basic operating instructions. Common applications include low-voltage development boards, smart home controllers, sensor monitors, handheld instruments, teaching kits, DIY electronics, appliance panels, access systems, medical device interfaces, and industrial control units. Its compact structure and I2C communication make it practical for space-limited designs.
