The PCB features silkscreen markings for various components; please refer to these markings when soldering. 2. Resistors are non-, but they have different resistance values; ensure you distinguish between them during soldering. 3. Electrolytic capacitors are : the longer lead is the positive (+) terminal, and the shorter lead is the negative (-) terminal. Ensure they are oriented according to the silkscreen markings on the PCB. 4. For LEDs, the shorter lead is the negative terminal, which corresponds to the flat side of the component footprint on the board. 5. When connecting the power supply wires to the terminal block, be sure to identify the positive and negative terminals correctly; do not reverse the polarity.
