2. Standoffs: Attach the 4 standoffs (#ST-10-23) to the PCB with 4 M3x6 screws (part #FA-60-37).

3. Resistors: The values of resistors are given by a series of colored stripes. There are several
tutorials online describing how to decode these stripes, but we will simply tell you the values,
part numbers and stripe colors. “Figure 3: Component Values And Locations” is a good
reference. The white graphics on the component side of the board also give reference to the part
number and value. If you are color blind or can’t see the stripes clearly, then you must use your
digital multimeter to measure the resistance of each resistor.
Resistors are not polarized, meaning they can be installed into their holes in either direction. It
doesn’t matter which lead goes into which hole.
The hole spacing of the resistors on the circuit board allows the leads to be (gently) bent 90
degrees at the body of the resistor (8). This allows the resistors to slip into their holes very easily.
a. Start with the 1K resistors (R4 - 11, R14), labeled BROWN, BLACK, BLACK, BROWN,
BROWN. Compare to its picture in the BOM. Find their locations on the circuit board; install
and bend the leads as described above (8,9,10). Don’t solder any of them until all 14
resistors are installed; just bend the leads to keep them in place.
