This is a MAX7456 OSD(On Screen Display) shield for Arduino. Users can easily interrupt and overlay text and/or graphics onto a video signal (PAL or NTSC).
It is just about “plug-and-play” with an Arduino board. Plug this shield on Arduino main board and upload the test sketch. Plug in your video signal to “Video In” and plug your TV into “Video Out”.
- Current consumption 100mA, worst case
- 5V SPI interface
