Feature
The Wireless TV Shield gives your OpenMV Cam a way to wirelessly transmit video at high speed over a long-range. It works using an SPI to NSTC chip attached to a 5.8 GHz analog broadcast chip. The Wireless TV Shield is as easy to use as the LCD shield and only requires you to init() is followed by calling display() to set the frame buffer in the NTSC generator chip. Your OpenMV Cam’s firmware includes built-in support for the wireless TV shield and OpenMV IDE comes with example code.
Applications
If you’ve ever wanted to mount your OpenMV Cam to a drone and transmit video back to an FPV screen this shield makes it possible. You just need to get a display capable of showing 5.8 GHz analog NSTC video.
Notes
The Wireless TV Shield only outputs NTSC video (not PAL – this is because the video generator chip requires a fixed freq crystal). You can get access to the analog video via the 3 holes on the front the board where (video/VIN/GND) are broken out.
