Overview
Bluetooth 4.1 Audio Receiver Module 10 pcs 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 ten 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 can pair with it just like 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 speakers. This set is ideal for DIY enthusiasts who want to equip a larger number of devices at once, prepare materials for a club or workshop, and have plenty of spare modules.

The sound outputs from the stereo jack 3.5 mm socket, to 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, allowing the output to 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 search for a special adapter. For permanent installation, there is a soldering pad BAT available 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 a blue LED indicates the connection.

The module is supplied as a bare board without a casing, so protect it from moisture, dust, and short circuits during installation. 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, as this may reduce the range. 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 ten is a practical solution for getting music from a mobile phone to several devices that do not have Bluetooth. Thanks to its compact dimensions 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, building your own speakers, and other DIY projects.
