Yesterday, John and I used eagle to build the schematic for the sensor expansion board for the SunSPOTs. The board will support
1 GPS receiver.
2 Cricket sensors
1 BTA connection (vernier analog sensors)
We then ran the drill files through a Roland engraver to drill the holes through the board.
Today , we used a press and peel backing to place the imprint on the board on both sides of the board to prepare the board for etching. After that was done, the board was etched and cleaned. Now it is ready for all of the components to be soldered down.
