We launched a Indiegogo campaign where we offer a series of digital I/O modules :http://igg.me/at/kunio
Via an SPI bus + some I/O pins, or just up to 7 simple I/O pins, you can add a huge number of digital in- and outputs in a modular way.
By using any microcontroller or Single Board Computer of your choice, you can create a powerful device (kind of PLC) that is accessible from the internet and has lots of storage and features using your own development tools.
The next step is to add more analogue inputs and outputs to this concept, without the need for more I/O pins.
I hope you enjoy this.
If anyone has remarkt about these modules, please let us know. With your help, we can make any single board computer more accessible for hardware newbies.
