LPC1752 IO board

A few years ago I was so fascinated by the idea of free software, I decided to design simple  IO board using only free tools on Linux. I sued applications called gschem and pcb. I also assembled the board. As you can see on the picture below I am not good at it and some parts of the PCB are burned.

Now I use the board to enhance my daughter’s interest in technology by controlling babbles.
