The WH1602V2 series is a 16x2 monochrome character LCD display module designed with a COB (Chip-on-Board) structure for high durability and reliability. With a compact profile of just 0.7 mm, this module integrates the ST7066U controller IC and operates with the 6800 parallel interface by default. For projects requiring more flexibility, SPI and I2C interfaces are available via the RW1063 controller IC, making it versatile for various embedded systems and industrial applications.
This display features a 2-line, 16-character layout, with a diagonal size of 2.26 inches. It supports multiple backlight options—including blue LED, red, white, green, and yellow-green LEDs—all powered by 2908 LED dice with a long lifespan of 50,000 hours. This ensures the module provides clear visibility and reliable operation in a range of environments.
