FPGA-bot Plexiglas Base with wheel slots and approximate drill hole locations for the
UP3 board. Verify the exact dimensions and mounting hole locations for each individual FPGA
board.
Mount the toggle switch (part #8) in the hole provided in the base. If available,
Loctite or CA glue can be used on the switch mounting threads to prevent the
switch nut from working lose. Solder the red wire (+7.2V) from the battery
connector to one of the switch contacts. This is the connector with wires that
plugs into the battery pack connector (part #4). Solder one of the twin lead
wires (part #9) to the other switch terminal. Solder the other twin lead wire to
the black (GND) battery connector wire and insulate the splice with heat shrink
tubing or electrical tape (part #10).
Route the twin lead wire through the hole provided in the base. A small knot in
the twin lead on the bottom side of the base can be used for strain relief. Solder
the power connector (part #11) to the other end of the twin lead wire on the top
of the base. The center conductor is +7.2V and the outer conductor is ground on
the power connector.
