This is just a board I made to work with at school because normally I would not build anything on pic. I just wanted to show once again, that using the photo etching technique and some effective component placing you can obtain really nice results wether your building trough hole or SMT. The board has a quad op-amp for inputing and outputing analog signals and a max232 to provide a serial interface. It will be mainly used to gather data from sensors and send it on the serial interface to a computer.
