Dear, We have a campaign running on Indiegogo : http://igg.me/at/kunio We offer a robust and modular I/O expansion system, up to even hundreds of I/O or more. It uses a very simple interface ( like SPI with a few bits. ) We will also offer analog in and outpus in the near future, within the same concept. If you have any questions, just let me know. I hope this could help you.
