 This was one of my first doublesided and surfacemount boards. I made this board using Eagle for layout and then I used [[http://​www.batchpcb.com|BatchPCB]] to manufacture the board. The board operates correctly, however, if I were to revise it, I would use a larger SMT resistor than the 0402 size. The board will be controlled via I2C from a PIC microcontroller,​ initially for the pressure sensor and later for other projects. This was one of my first doublesided and surfacemount boards.
