Fourth-generation low-cost video information overlay module, now available in a rugged 2x20 header connector format with industrial temperature specs as well as the original 30-pin SIMM format. BOB-4 lets your microcontroller or PC display text and vector graphics on standard TV monitors. With large user-definable character sets, BOB-4 also supports bitmap graphics and multiple languages. BOB-4 generates background video on-board, or automatically genlocks to your video source and superimposes characters over the image. Printable characters and commands drive BOB-4 through fast SPI or RS-232 style data links, much like a serial terminal or printer. BOB-4 links directly to most microcontroller chips and modules. NTSC and PAL video standards are supported in a single hardware version.
Key Features:
- Simple hookup; requires just 5VDC, serial data, video I/O
