Audio amplifier module 2x35W class AB 9-14.4V TDA7377 + heatsink + 3.5mm jack

Audio amplifier module 2x35W class AB TDA7377

High-quality audio amplifier module based on the TDA7377 IC. It operates in class AB and delivers 2 x 35W output power into a 4Ω load at a supply voltage of 14.4V. The module requires power in the range of 9V to 14.4V (recommended voltage is 12V). The board includes a built-in heatsink for efficient heat dissipation during operation. Smooth volume adjustment is provided by an integrated potentiometer. The input signal is connected via a standard 3.5mm stereo JACK connector. The module works well as an output stage in audio projects, including as a sound add-on for Arduino, ESP8266, ESP32, and Raspberry Pi.
