Key Specifications

LCD 1602 Wemos is a 16x2 character display module designed for Wemos boards and other microcontroller platforms that need simple text output with fewer wiring connections. The JXD1602A-IIC model uses an 80.0×36.0×17.5mm module size and a 64.5×14.0mm viewing area, providing enough space for two rows of status information. It supports 3.3V/5.0V drive voltage, ST7066/AIP31066 controller IC options, IIC/I2C interface communication, red LED backlight, and FSTN positive display technology for clear character visibility.

Design Standards

LCD 1602 Wemos focuses on compact wiring, stable signal transmission, and convenient integration with small development boards. The I2C interface helps reduce occupied GPIO pins, which is useful when a Wemos or similar controller must also connect sensors, relays, buttons, or wireless modules. Its 06:00 viewing direction supports front-panel installation, while the -20°C to +70°C operating range allows dependable use in varied electronic environments. The module also supports customization for backlight color, display style, character requirements, and project housing needs.

Applications

LCD 1602 Wemos is suitable for projects that need quick, readable two-line information display without a large graphic screen. It can show WiFi status, sensor values, temperature readings, timer data, device modes, warning messages, and simple menu prompts. Typical uses include Wemos D1 mini projects, ESP8266-based smart devices, Arduino learning kits, IoT terminals, home automation controllers, small meters, access systems, laboratory tools, appliance panels, and DIY electronics. Its compact format makes it practical for prototypes and finished products where space and wiring efficiency matter.
