There is no SECAM version of Sophia2 and there won't be. There are two SECAM version of Sophia1: RGB and DVI. The DVI version exists only as a ready to produce design and has never been released. There wasn't a demand. The SECAM RGB version was produced in the number of about a dozen and sold out. The new production is possible but uneconomic because of global chip shortage and very high prices keeping by the stock owners. The only option is an adapter that matches the Sophia2 pinout to the SECA
