Resistors
The value of a resistor is indicated by colored stripes on its body. In all cases the fifth stripe is brown (indicating 1%
tolerance), so that stripe has been omitted from the chart below.
The resistor leads need to be bent close to the body of the resistor. Hold the resistor body and press down on each
lead right at the body to make a U shape.
We recommend that you start with the 1K resistors because that is the most common value. Once they have been
soldered onto the PCB, it will be much easier to find the other refdes values.

Ceramic Capacitors
Ceramic capacitors are very small tan or blue blobs. Their value is marked on them with a three digit code. The
marking is rather small, so you may have to use a magnifying glass to read them.
We recommend that you start with the 0.01 uF capacitors because that is the most common value. Once they have
been soldered onto the PCB, it will be much easier to find the other refdes values.
