WO1602F is a 16x2 COG Character LCD display module featuring the ST7032 controller IC with 6800, 4-line SPI, and I²C interfaces. The module measures 72.1 × 29.6 × 9.4 mm, with a 61.0 × 15.1 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 WO1602F suitable for embedded applications where installation space is limited.
The WO1602F 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 6800, 4-line SPI, or I²C interfaces.
