My IR module was designed for use with an embedded Linux system. I chose the Olimex A10-OLinuXino-LIME as it looked powerful and a good starting point for an Internet Radio project that I wanted to do.
The goal was to make a compact IR decoder that processes the signals from a TV-remote and gives a Linux based embedded computer the codes.
Pre-built version of the module.
