8002B Power Amplifier Module Speaker Audio Amplifier DIY Power Amplifier Sensor Suitable For Arduino
Product Description:
-
The main components of this module are an adjustable potentiometer, a speaker, and an audio amplifier chip; the main function is: it can amplify the output small audio signal, which is about 8.5 times, and can play through the built-in low-power speaker It can also be used to play music. As an external amplification device for some music playback devices, please pay attention to firstly adjust the volume to the minimum, and then slowly increase it to prevent the speakers from being burned out.
-
When we connect the microcontroller to test, we can input square waves of different frequencies and different durations at the signal end to edit the sound from the speaker. At the same time, the module is compatible with various microcontroller control boards, such as arduino series microcontrollers. When used, we can stack a sensor expansion board on the microcontroller. The module is connected with its own wires, and then connected to the sensor expansion board, which is simple and convenient. At the same time, the module comes with a positioning hole with a diameter of 3mm, which is convenient for you to fix the module to other devices.
