LCD 1602 I2C Arduino - SJXD1602B-IIC （STN Positive）

LCD 1602 I2C Arduino is a 16×2 character module for Arduino projects, embedded controllers, and compact user interfaces. The SJXD1602B-IIC design uses IIC/I2C communication, so developers can connect the display through SDA and SCL while keeping more pins free for other functions. It supports 3.3V/5V operation, ST7066/AIP31066 controller options, white LED backlight, and STN positive display mode. It can present readings, menu text, alerts, counters, and operating status in instruments, appliances, automation systems, and DIY electronics.

Parameters:

• High contrast, wide-temperature operation
• Low power consumption, high anti-interference performance
• Support for multiple color combinations
• Provide a complete set of one-stop technical information and source code
• Supports customization
• Supports 1-3 day samples
• High quality and cost-effective
• The fastest batch delivery can be achieved within 15 days

Key Specifications

LCD 1602 I2C Arduino is a 16×2 character display module designed for simple text output on Arduino-based control projects and compact embedded devices. The SJXD1602B-IIC model features an 85.0×30.0×18.0mm outline size and a 64.5×14.0mm viewing area.
