PAM8403 Stereo Amplifier Set of 5 Modules 2 x 3 W Volume Control Potentiometer with Switch Power Supply 5 V Board 27.9 x 19.9 mm for Workshop
You already have the maximum available quantity in your cart.
The package includes five individual stereo amplifiers with the PAM8403 chip, each delivering a power output of 2 x 3 W to a pair of small speakers. A larger set is beneficial for workshops, electronics clubs, teaching, or for hobbyists building multiple devices at once. The modules are powered by low voltage, so a standard 5 V power source is sufficient, such as from a computer USB port or charger. Each board has an integrated rotary potentiometer, allowing you to smoothly adjust the volume of both channels. The green printed circuit boards are small and easily fit into compact enclosures.
The connections are straightforward and manageable even for a beginner with a soldering iron. At the edge of the board, there are soldering points for power +5 V and ground, for audio input of the left and right channels with a common ground, and for the outputs of both speakers. The potentiometer has a built-in switch, so by turning the knob to the end, you can turn off the amplifier and by turning it again, you can turn it back on and increase the volume. The board is equipped with a filtering capacitor that smooths out the power supply voltage. The amplifier operates in class D, so it does not heat up excessively during normal operation and does not require a heatsink. The board does not have its own connectors; wires are connected by soldering, ensuring a solid and reliable connection even in moving products. The audio signal can be sourced, for example, from the headphone output of a phone, computer, MP3 player, or another audio module.

- Package Contents – 5 pcs PAM8403 stereo amplifiers, each with an integrated potentiometer
The module is suitable for building your own active speakers for computers, for powering children's toys, doorbells, voice modules, or simple radios. Connect the speakers directly to the outputs of the board and always disconnect the power supply before soldering. Protect the board from moisture and short circuits, ideally placing it in a plastic enclosure. When soldering wires, work with a slightly heated soldering iron and keep the connections short to avoid unnecessary noise. For the best results, use speakers whose power matches that of the amplifier, and a power supply with sufficient current reserve.
The set of five PAM8403 amplifiers supplies the workshop for a range of projects and is more cost-effective than purchasing individually. Thanks to the power supply of 2.5 to 5 V, you can connect each module to a USB charger, power bank, or computer. The potentiometer with switch replaces a separate button and volume control. The small boards are easily integrated into custom enclosures, educational kits, or old speakers. It is a practical supply for anyone who regularly builds audio devices.
