1N4148 Diode (±)

Diodes are red and black glass cylinders. There are four diodes, and they all look similar, but D2 is different. D2 is a

switching diode and has “1N4148” printed on it in very small type. An easier way to tell D2 apart is that D2 is loose,

while the other three diodes are connected together on a piece of tape.

Diodes are polarized, so it is important that the right lead goes in the right hole. When inserted into the PCB, the

black stripe on the diode must line up with the stripe on the part outline on the PCB. The diode leads need to be bent

into a U shape in order to insert them into the PCB. Bend the leads by holding the diode body and pressing down on

each lead close to the body.

Schottky Diodes (±)

D1, D3, and D4 are Schottky diodes and have “BAT85” printed on it in very small type. When inserted into the PCB,

the black stripe on the diode must line up with the stripe on the part outline on the PCB.

Resistors

Resistors are cylindrical parts with colored stripes indicating their value. The resistor leads need to be bent into a U

shape in order to insert them into the PCB. Bend the leads by holding the resistor body and pressing down on each

lead close to the body.

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.
