Overview
Bluetooth 4.1 Audio Receiver Module 5 Pieces with USB-C Connector Decoder Boards 30 x 30 mm Stereo Jack 3.5 mm Power Supply 3.7 to 5 V Red

In the package, you will receive five identical wireless audio receivers. Each one is a small electronic board that adds Bluetooth to older speakers, amplifiers, headphones, or home audio systems. The module operates with Bluetooth 4.1 technology and is powered via a USB-C connector. A phone, tablet, or laptop pairs with it just like with a regular wireless speaker, and music is then played directly to the connected device. The board measures 30 x 30 mm, making it suitable for smaller enclosures or inside a speaker. The set is ideal for DIY enthusiasts who want to revive multiple pieces of older technology at once or have spare modules on hand.

The sound comes from the stereo jack 3.5 mm socket, into which you can connect headphones, active speakers, or the AUX input of an amplifier. Next to the socket, there are also soldering pads on the board for the left and right channels, so the output can also be wired directly to the amplifier's input. Power is supplied via a cable with a USB-C connector, which is used by most phones, chargers, and power banks today, so you do not need to look for a special adapter. For permanent installation, there is a soldering pad BAT for an external lithium cell with a voltage of 3.7 V. The module operates with a power supply voltage of 3.7 to 5 V and connection is indicated by a blue LED.

The module is supplied as a bare board without a case, so when embedding it, protect it from moisture, dust, and short circuits. It is advisable to secure the board using the mounting holes in the corners and ensure that the underside does not touch metal parts. The antenna is printed directly on the board, so do not cover it with metal, or the range may be reduced. When soldering power and audio wires, proceed carefully and observe the correct polarity.

A wireless receiver with a USB-C connector in a pack of five pieces is a practical solution for getting music from a mobile phone to several devices that do not have Bluetooth. Thanks to its compact size and power supply via USB-C or battery, it can be easily integrated into a home project. The output via the 3.5 mm jack can connect both headphones and an amplifier, and the soldering pads allow for a solid connection. The red board with a range of 15 m is suitable for repairing old radios, teaching in clubs, custom speakers, and other DIY projects.
