EVAL_KIT_WO256128-XXXA#FC

Development Board for Graphic LCD 2.9'' 256x128, COG, 3.3V, Interface 6800/8080/SPI/I2C (Excluding LCD)

DESCRIPTION

Evaluation kut for LCD COG P/N WO256128-xxxA#FC. WO256128-xxxA#FC is a monochrome graphic LCD module made of 256x128 pixels, diagonal size 2.9 inch. This LCD Module is built in with ST75256 controller IC, it supports 6800 8-bit, 8080 8-bit parallel and 4-wire serial SPI and I2C interface. It has the same outline dimension, and VA size and same power supply 3.3V as WO12864-XXXD3#FC, but it has a much higher resolution and performance: the customers don’t have to change the mechanical design for their applications.

Operating temperatures from -20℃ to +70℃; storage temperatures range from -30℃ to +80℃. It is available for different LCD mode options, STN Negative, FSTN Negative (Double film) and FSTN positive and with LED backlight options, like white LED. Please contact with us if you need different LCD type and LED combination.
