WO1602B is a 16x2 COG Character LCD display module featuring the ST7032 controller IC with an I²C interface and a metal pin connection. The module measures 85.0 × 30.0 × 6.2 mm, with a 76.0 × 18.0 mm view area. It supports both 3 V and 5 V logic supply voltage (VDD) options and is designed for operating temperatures from -20°C to +70°C and storage temperatures from -30°C to +80°C.
The COG (Chip-on-Glass) construction provides a compact and low-profile module design, making the WO1602B suitable for embedded applications where installation space is limited.
The WO1602B series is available with multiple LED backlight color options, providing greater flexibility for different product designs. It is suitable for industrial equipment, security systems, medical devices, handheld instruments, and other embedded applications requiring a 16x2 character LCD with an I²C interface.
