I made this board using Eagle for layout and then I used 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. text/html 2014-11-13T18:50:14+00:00 Anonymous (anonymous@undisclosed.example.com) IO Board https://www.photonicsguy.ca/projects/electronics/ioboard?rev=1415904614&do=diff IO Board 16 Bit Digital input, 16 Bit Digital Output.
