The GOK12832A-25SM is a 240x64 Intelligent Graphic OLED display designed to fit into 1U form factors. OLED technology improves readability by offering a high contrast display with wide viewing angles and requires significantly less power to operate than VFD or even LCD units. Engineered to quickly and easily add an elegant graphic HMI to any application. Multiple communication protocols such as Serial RS232, TTL, I2C, USB and RS422 communication models allow the GOK12832A-SM Graphic OLEDto be connected to a wide variety of host controllers.
Our Graphic OLED provides you with a cost-effective industrial HMI user interface solution for that great product/project you are developing. On board memory for Fonts and Bitmaps! This graphic OLED displays graphics and text in any font, style, justification and language, all with the convenience of a 25-key keypad matrix will allow fast development for any application.
