Warm Tips

1. The PCB board has printed silk-screen markings for each component; please solder according to the markings.

2. Resistors have no polarity, but there are different resistance values — pay attention to distinguishing them when soldering.

3. Electrolytic capacitors and LEDs have positive and negative poles; the long lead is positive (+) and the short lead is negative (−). When soldering, pay attention to matching the polarity indicated on the PCB board.

4. When connecting the power supply to the circuit board, be sure to match the positive and negative poles — do not reverse them.

5. The microphone has 3 green stripes on the negative side.
