TDA2030 Audio Amplifier Module – 18W, 6-12V

This module is widely used in car stereo receivers, medium-power audio equipment, and home audio systems due to its small size, high output power, and built-in short-circuit and thermal protection circuits. For Arduino use, connect the VCC pin to a 6-12V power source, GND to ground, and the audio input to the designated pins (e.g., via a 3.5mm jack or direct signal input), with the speaker output taken from the PCB terminals. The module’s compact design, typically around 32x24mm, and minimal component requirements make it ideal for hobbyists. It operates effectively from -10°C to +50°C and requires a heat sink for prolonged high-power use to prevent overheating.

Note: Ensure proper ventilation and avoid exceeding the voltage range to maintain performance and safety.
