WO240128B2 is a PCB version of the WO240128B 4.82-inch 240x128 graphic COG LCD module. By integrating a PCB onto the COG module, it provides easier installation and system integration while retaining the same display specifications. The module features the ST7586S controller IC and supports a default 6800 8-bit parallel interface, with optional 8080 8-bit parallel and 3-Line or 4-Line SPI serial interfaces. It operates with a 3.3V logic supply.
The module measures 140.0 x 84.0 x 9.7 mm, with a 114.0 x 64.0 mm view area and a 107.98 x 57.58 mm active area. It features an LED backlight.
The integrated PCB provides an onboard circuit layout and mounting holes for secure installation. Three connector pitch options are available: 2.54 mm (default), 1.0 mm, and 0.5 mm. An optional 5V logic supply is also available for designs requiring 5V compatibility.
Different LCD modes and LED backlight options are available. Click Add to Inquiry above and specify your requirements in the inquiry message.
