A fun video generator board with 4 distinct video outputs
For 4x Video Display Arduino Shield / Feather Wing
Thanks to the github applications, one can set it up and start developing quite fast. Wolfgang was responsive and answered to all my questions.
Probably the best is to use this shield with an arduino board that has a fast SPI interface and a bit of processing power under the hood. I am using an Genuino 101 (Intel Curie chip) that has a 32Mhz 32bit RISC processor, floating point acceleration, and an 16Mhz SPI clock, but still an SPI transfer feels sluggish.
The resistor R32 needs to be removed for the boards (like my Genuino 101) which are having a different IOREF voltage (e.g., 3.3v) than Vicsp voltage (e.g., 5v).

Claudiu, I am glad that I could answer all your questions and you are having fun with the board.
Thanks for documenting the IO voltage modification here, I am going to add this to the user manual.
For a fast board I can also recommend the Adafruit Feather M4 Express.
Cheers, W.
