The integrated amplifier circuit operates according to the Class-D principle and delivers the input signal at up to 5 W per channel at full power, while keeping power consumption low.\u003c\/p\u003e \u003cp\u003eIt can be powered by sources between 2.5 and 5.5 volts, making it suitable for direct connection to USB ports as well as 4-cell AA battery packs or LiPo batteries. The integrated potentiometer enables manual volume control at any time. The input impedance is designed for low-impedance signals, allowing clean audio signals at low levels to be transmitted over cable lengths of several meters.\u003c\/p\u003e \u003cp\u003eApplications include portable radio systems with audio playback from microcontrollers, battery-powered toys with sound output, voice modules for robotics projects, and Bluetooth amplifiers using single-board computers. It can also be used as an amplification stage for alarm sirens in automated models or for real-time audio feedback during sensor tests.\u003c\/p\u003e \u003cp\u003eA power source within the specified voltage range is required for operation. The output power depends on the load, and typical 4-ohm or 8-ohm speakers are suitable. The module is not intended for expanding household power grids and cannot process continuous high-level audio sources without going into saturation.\u003c\/p\u003e \u003ch3\u003eSafety information\u003c\/h3\u003e \u003cp\u003eThe module operates with low DC voltage and is intended exclusively for building prototypes and for testing and development purposes. For applications involving increased audio power (over 5 W) or connection to power grids, consult a qualified electrician before commissioning.\u003c\/p\u003e \u003ch4\u003eScope of delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x PAM8403 audio amplifier module with potentiometer, 2x 3W stereo\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":66045450715485,"sku":"F23108005","price":1.96,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/audioverstaerkermodul-pam8403-mit-potentiometer-2x-3w-stereo-funduino-2476573.jpg?v=1791490469","url":"https:\/\/funduino.com\/en\/products\/pam8403-audio-amplifier-module-with-potentiometer-2x-3w-stereo","provider":"Funduino","version":"1.0","type":"link"}
