TDA2030A amplifier board, mono amplifier, potentiometer control electronic production kit. It adopt TDA2030A amplifier integrated block, with volume adjustment potentiometer and heat sink. Its purpose is a simple volume amplifier without a preamplifier circuit. The input sound source is amplified without modification and directly drives the speaker to make a sound. The sound is original and pure. This amplifier board uses TDA2030 amplifier IC to form a pure post-stage amplifier, single power supply, input voltage is single power supply AC 9V-15V, reasonable component layout, strong power, almost no static noise, good listening experience, few peripheral components, easy installation, very suitable for home audio system modification or installation, widely used in various active speakers. The kit includes a circuit board, a full set of components, circuit schematics, etc.
