WO256128-85HA2#FC

Graphic LCD 2.9'' 256x128, B/L white, FSTN white pos, COG + PCB with screw holes, 3.3V, Interface 8080

DESCRIPTION

COG LCD display with a PCB board on module which is made of 256x128 dots, diagonal size 2.9 inch. It is built in with ST75256 controller IC, it supports 8080 8-bit parallel (default), 6800 8-bit and 4-wire serial SPI and I2C interface, power supply voltage 3.3V, 1/128 duty, 1/12 Bias. The advantage is having circuit layout on PCB board and with screw holes which make modules can be fixed on customers’ applications easily. Also, there are three kinds of connector pitch sizes of 2.54mm (default), 1.0mm and 0.5mm for options. Also have VDD 5V power supply voltage for optional.

Operating temperatures from -20℃ to +70℃; storage temperatures range from -30℃ to +80℃. Available for FSTN positive Transflective with white LED backlight. Please contact us if you need different types of LCDs or LED combinations.
