Features:

1. Multiple Connectivity Options: This audio decoder board includes a DC interface, AUX input, headphone output, and is compatible with the XH2.54 interface. Additionally, the Type-C interface supports both power supply and USB sound card functionality. The QCC5125 model allows for EQ adjustment via official software through the USB interface, making it ideal for software enthusiasts.

2. Outstanding Wireless Range: The onboard antenna provides a transmission distance of up to 50 meters in open environments without requiring an external antenna. For installations within metal enclosures, use the IPEX1 placeholder to add an external antenna to prevent signal lost, ensuring uninterrupted performance.

3. Enhanced Audio Performance: Equipped with the QCC5125+PCM5102A chipset, this decoder board ensures lossless transmission and decoding, delivering exquisite sound quality. The high frequencies are smooth, mid-ranges robust, and low frequencies powerful and elastic. Key audio parameters include a dynamic range of 112dB, a signal-to-noise ratio of 112dB, and distortion at -93dB, providing an exceptional auditory experience.

4. Versatile Output and Control: The device features an I2S output interface for connectivity with amplifiers and a key expansion interface for functionalities such as track switching, volume adjustment, and playback/pause. Additionally, a "Bluetooth connection cancel button" allows users to easily disconnect from unknown devices by pressing for 3 seconds.

5. High-Quality Componentry: Using high-quality capacitors enhances the sound by improving parameters such as dissipation factor, leakage current, ripple current, and ESR. These components provide improvements in speed, dynamics, texture, and density across high, mid, and low frequencies, delivering a comprehensive upgrade in sound quality.
