DFRobot FireBeetle OSD -Screen Display Character Overlay Module AT7456E 512B EEPROM for Road Cameras Home Automation

Descrizione di DFRobot FireBeetle OSD -Screen Display Character Overlay Module AT7456E 512B EEPROM for Road Cameras Home Automation

-screen Display is a screen menu adjustment method: This is a technology that adds various menu characters to the screen. DFRobot's newly launched OSD video character overlay module uses the AT7456E high-performance video character overlay chip, which integrates 512Byte of EEPROM user-defined storage space. It is a single-channel, monochrome -screen display generator with functions such as video driver, synchronization separator, and video separation .
After connecting to the video source (AV signal), a layer of 540x192 pixels can be overlaid the video, which can display 16x30 characters. Users can call the font library to display the corresponding text or pattern.
Firebeetle OSD character overlay module is compatible with the FireBeetle interface and can be directly plugged into the FireBeetle series motherboard.
