Specifications

Locate the 2.2K resistor (marked “222”) just below to the left of the processor. Solder it in
place, using the same procedure that you used for the .1 uF capacitor.
__ Mount the 4.7K resistor
Locate the 4.7K resistor (marked “472”) below and to the right of the processor. Solder it in
place, using the same procedure that you used for the .1 uF capacitor.
__ Mount the 10 uF capacitors
Locate the two 10 uF capacitors, one just above and one just below the voltage regulator. Note
that they are a bit larger than the other resistors and capacitors. Solder them in place.
This completes the surface-mount part of the assembly. Untape the board from your work
surface. At this point, you may find that a “third hands” board holder will come in handy…
__ Mount the Red LED
Locate the spot for the Red LED, it’s the one on the bottom right hand side of the board
marked “ON”. Note that it is polarized; you need to match up the LONG lead on the LED with
the “+” pad on the board. Insert in in place, and use a small piece of paper tape to hold it to the
board. Turn the board over, solder the leads to the pads, and clip the excess leads. Save the
clipped leads… you’ll need them later.
__ Mount the Amber LED
Locate the spot for the Amber LED, it’s the one marked “BTN” on the lower left side of the
board. Note that it is polarized; you need to match up the LONG lead on the LED with the “+”
pad on the board. Insert in in place, and use a small piece of paper tape to hold it to the board.
Turn the board over, solder the leads to the pads, and clip the excess leads. Save the clipped
leads.
__ Mount the Buzzer
Locate the spot for the buzzer. Note that it IS polarized, the long lead needs to go into the hole
marked “+”. Insert the leads into the holes, and hold it in place with a small piece of paper
masking tape. . Turn the board over, solder the leads to the pads, and clip the excess leads.
__ Solder the Screw Terminal Block (Optional)
