The Alix 2D13 has pins for GPIO and I2C – see http://pcengines.ch/alix2d13.htm
There is generously 1 GPIO pin in 2D13, but I2C changes things. That I did not notice at all..
I actually use Alix 2D13 as a Debian-based home (openvpn)router with some other functions like web server (lighttpd) and webcam with motion-triggered recording (motion, behind lighttpd). I also wanted to connect door sensor and fire detector to it using GPIO but I eventually found out that there are no GPIO pins on the board. Although the product description (http://pcengines.ch/alix2d13.htm
) says that one of the changes from ALIX.2C is "add pins for use as GPIO", the product manual (e.g. http://www.corpshadow.biz/bizs.....manual.pdf
) says "The LCP port can also be used to connect a super I/O device. Unlike SC1100 based WRAP boards, this port cannot be reprogrammed as GPIO pins."
So my question is, why do you guys think that ALIX 2D13 has pins for GPIO (wallabybob), or at least a single one (Troyhy)?
However, except for GPIO, I can confirm that ALIX2D13 is a perfect hardware for a VPN router, especially a Linux-based one. It even comes with a crypto acceletor for AES128 (unfortunately not AES256).
