{"title":"FireBeetle OSD Character Overlay Module","handle":"firebeetle-osd-character-overlay-module","url":"/products/firebeetle-osd-character-overlay-module","description":"The FireBeetle OSD Character Overlay Module adds on-screen character display to composite video (AV) signals. Based on the AT7456E OSD chip, it overlays up to 16×30 characters onto NTSC or PAL video feeds — ideal for adding timestamps, telemetry data, or status information to camera and monitoring systems.\n\nThe module communicates via SPI and is directly compatible with DFRobot's FireBeetle mainboard series. It includes 512 bytes of EEPROM for user-defined characters, a built-in font library, and supports blink, inverse colour, and per-line brightness control.\n\nKey Features\n\n\nAT7456E OSD Chip – Single-channel on-screen character overlay\n\n16×30 Character Display – Up to 480 characters at 18×12 pixel resolution (540×192 total)\n\nNTSC & PAL Compatible – Works with both video standards\n\n512-Byte EEPROM – Store custom user-defined characters\n\nBuilt-In Font Library – Ready-to-use character set\n\nCharacter Effects – Blink, inverse colour, and background control\n\nPer-Line Brightness – Adjustable lightness on a line-by-line basis\n\nSPI Interface – Standard communication with microcontrollers\n\nFireBeetle Compatible – Plugs directly into FireBeetle mainboards\n\n\nSpecifications\n\n\nOperating Voltage – 3.3–5 V\n\nOperating Current – 75 mA\n\nResolution – 540 × 192 pixels\n\nCharacter Grid – 16 × 30 characters (18 × 12 pixels each)\n\nDisplay Colour – Single colour (white)\n\nSignal Source – AV (composite video) I/O\n\nInterface – SPI\n\nOperating Temperature – −10°C to +85°C\n\nDimensions – 58 × 29 mm\n\n\nIdeal For\n\nSecurity camera timestamp and status overlays\nFPV drone telemetry displays\nHome automation monitoring systems\nRoad camera and surveillance character display\n\n\nPackage Contents\n\n1× FireBeetle OSD Character Overlay Module\n\n\nResources\n\nDFRobot Wiki – OSD Character Overlay Module\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":6362,"title":"Default Title","sku":"DF-DFR0515","price":17.07,"on_sale":false,"in_stock":true,"available_quantity":42,"option1":"Default Title"}]}
