Frequently asked questions
What speaker and power supply should I use?
Use a DC supply within the module's rated voltage range and a speaker with matching impedance, typically 4 Ω for TDA2003 designs. An undersized supply causes distortion, and higher output power needs a heatsink.
How do I wire the module?
Connect the DC supply to the + and - pads, the audio source to the input pad (through a volume control if provided), and the speaker to the output pads. Keep speaker and input wires away from the supply wires to reduce noise.
