Due to the trade war between China and the USA, FedEx and DHL have suspended shipping from Hong Kong to the USA. We have some inventory in Shenzhen which we can still ship to the USA - which is not affected at the moment. Otherwise, USA orders will be on hold till May 2nd while we wait for for more clarity. We are operating as normal for non-USA customers.

The Wireless TV Shield gives your OpenMV Cam a way to wirelessly transmit video at high speed over a long range. It works using a SPI to NTSC chip attached to an 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() it 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.
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 to showing 5.8 GHz analog NTSC video.
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.
