PARTS LIST:

Bluetooth Audio Receiver [XY-BT-Min]

The Bluetooth Audio Receiver is a versatile device designed to facilitate wireless audio streaming from various compatible devices such as smartphones, tablets, and laptops. By leveraging Bluetooth technology, it enables seamless connectivity and high-quality audio transmission, eliminating the need for cumbersome cables. This receiver is perfect for upgrading conventional wired audio systems to modern wireless setups, offering enhanced convenience and flexibility in audio configurations.

DC-DC Power Module [B0505S-1W]

The B0505S-1W 5V to 5V Converter DC-DC Power Module is a specialized power conversion solution featuring ground noise isolation capabilities. It efficiently converts a 5V input voltage to a stable 5V output while effectively isolating ground noises, ensuring clean and reliable power delivery. This module is particularly valuable in applications where noise interference can degrade system performance, such as audio equipment, sensitive instrumentation, and communication systems.

DC-DC Buck Converter Step Down [Mini360 DC-DC HM]

The Mini360 DC-DC HM Buck Converter Step Down is a compact and efficient voltage regulator module designed for step-down voltage conversion. With its buck converter topology, it can efficiently lower higher input voltages to lower output voltages. In this specific setup, it is utilized to step down the voltage from a 17V rectifier bridge to 5V, providing a suitable power supply for the Bluetooth receiver. This module is widely used in electronics projects, portable devices, and automotive applications to provide regulated power supply, thereby enhancing system efficiency and reliability while maintaining a small footprint.

Other parts are universal PCB board, simple ON/OFF Switch and old lan cable.
