Fastrack "Test-Bed" for SD-Card Operations

This board was built in support of the GPS Logger project, as a "test-bed" prior to availability of the client's custom hardware:

• The Fastrack Supreme modem is fitted with an "IESM" plug-in card to provide a GPS receiver and IO signals;
• The IO signals are taken to the board, which breaks-out the SPI bus for the SD Card;
• The board also provides a 2.8V power supply for the SD-Card.
