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) https://www.photonicsguy.ca/projects/electronics/dgpsbeaconrx?rev=1415904614&do=diff DGPS-11 Beacon Receiver Si-tex DGPS-11 Beacon Receiver module mounted in a weatherproof housing.
