1. 6 pin SMD GPS socket (U2): Make sure all
the pins line up and are setting flush on the
pads before soldering. HINT: Use a clothes
pin to hold the socket in place on the
board and tack in place on one of the back
side pads. Check alignment of pins / flush
contact and finish soldering each pin.
2. Resistors (R1‐R10): Orientation for each
resistor is not critical; however, make sure
the correct resistor is placed in each bank.
Values are silk‐screened on the PCB.
3. 1N4148 diode (D1): Orientation is critical!
Insert the diode so that the black line on
the diode lines up over the silk‐screened
white line on the PCB.
4. 10uF capacitor (C1). Orientation is critical!
Insert the capacitor with the short lead in
the negative (‐) marked thru‐hole. The
capacitor is to be folded over in a horizontal
position prior to soldering.
5. 7805 5V regulator (U1): Ensure the
regulator is setting flat on the PCB prior to
soldering. After soldering one pad, ensure
it remains flat before soldering the other
two pads.
NOTE: If the regulator is not flat against
the PCB, it can cause interference with the
power and serial cable connections during
case assembly.
