The PAM8403 Volume Control Mini 2 Channel is a small, easy-to-use audio amplifier module that can use to power two 3W speakers. Mini PAM8403 Audio Amplifier module is powered by a 5V supply and has a built-in potentiometer for volume control. The PAM8403 module is also equipped with a power switch, so you can easily turn it on and off. This 2 Channel 5v Audio Amplifier Circuit Board allows the user to achieve high-quality audio reproduction from a stereo input. Additionally, it has a special feature that is, it can drive speakers directly from its output. This PAM8403 Volume Control Mini 2 Channel 5v Audio Amplifier Circuit Board of PAM series is different from basic PAM8403 Amplifier board as it gives us more control over the output generated by IC itself. The 3W PAM8403 amplifier board is a great choice for DIY audio projects, such as building your own portable speaker or adding sound to a robot. It is also a good option for people who want to improve the sound quality of their computer or TV speakers. The input voltage for the volume control on the PAM8403 amplifier is 5V. This means that the potentiometer that you use to control the volume must rated for at least 5V. You can use a potentiometer with a higher voltage rating, but it is not necessary. If you are using a potentiometer with a lower voltage rating, you will need to make sure that the input voltage to the amplifier is not more than the rated voltage of the potentiometer. Note: – Left and right channel “negative” connections should not connect together, otherwise it may damage the module. Speakers (load) should connect before power applied to the module. Please make sure the power supply is not more than 5.5V and please don’t do reverse polarity for “ ” and “-“, or else, it will burn the board.

It is a small, efficient, and affordable chip that can provide up to 3W of output power per channel. The PAM8403 is a good choice for projects where size and weight are important, such as portable speakers or robots. The PAM8403 Stereo Amplifier Module has 9 pins, which are as follows: VCC: This pin is the power supply input for the volume control. The voltage on this pin must be between 2.5V and 5.5V. GND: This pin is the ground pin for the volume control. IN: This pin is the input signal from the amplifier. OUT: This pin is the output signal from the volume control. MUTE: This pin is the mute control pin. A logic low on this pin will mute the output signal. SHDN: This pin is the shutdown control pin. A logic low on this pin will shut down the volume control. NC: This pin is not connected. VREF: This pin provides a reference voltage for the volume control. The voltage on this pin is typically 2.5V. POT: This pin is the potentiometer input pin. The voltage on this pin will vary depending on the position of the potentiometer.
