It receives audio data wirelessly via Bluetooth and outputs it in amplified form, either through a stereo jack socket or directly to two individual speakers. Since the amplifier is integrated, no separate component is required, making the board significantly more compact.\u003c\/p\u003e \u003cp\u003eThe output power is up to 4 W in mono mode, which is sufficient for small amplifiers. In stereo mode, each channel provides 2 W. With a 5 V supply voltage, the module can be connected directly to common microcontroller boards without the need for additional voltage converters.\u003c\/p\u003e \u003cp\u003eTypical applications include portable music playback via smartphone or tablet, alarm sirens with variable volume, notification sounds in automated projects, or audio feedback for robotics models. The Bluetooth connection is particularly useful for prototypes that need to communicate information about their surroundings acoustically.\u003c\/p\u003e \u003cp\u003eOperation requires a Bluetooth-enabled device such as a smartphone or portable computer. Speakers or headphones must be purchased separately, depending on the desired output method. The final output power depends on the impedance of the connected speaker.\u003c\/p\u003e \u003ch3\u003eSafety Notice\u003c\/h3\u003e \u003cp\u003eThe module is intended exclusively for building prototypes and for testing and development purposes. It must not be installed in or connected to the household power grid. If you are unsure about the power supply or correct connection, consult a qualified electrician before commissioning.\u003c\/p\u003e \u003ch4\u003eScope of Delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x 5V Mono\/Stereo 4.2 Bluetooth Audio Amplifier Module\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":66045163405661,"sku":"F23105763","price":3.38,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/5v-monostereo-42-bluetooth-audioverstaerker-modul-funduino-9174462.jpg?v=1791488830","url":"https:\/\/funduino.com\/en\/products\/5v-mono-stereo-4-2-bluetooth-audio-amplifier-module","provider":"Funduino","version":"1.0","type":"link"}
