ZK-QCC Qualcomm QCC3034 Bluetooth 5.1 Lossless Decoding Board APTX LDAC Audio Decoder Board TJ

Product Highlights: On-board antenna, the mission distance is about 50 meters in open space, no external antenna is required. If it is installed in a metal case to avoid signal shielding, you can purchase an external antenna for installation and reserve an IPEX antenna seat. There is a 12S output interface, which can be connected to a power amplifier with l2S input function, and a button expansion interface is left to realize the previous/next song switching, pause/play, volume adjustment, and strong expandability.There is a TYPE-C USB interface, which can realize PC sound card connection, or USB power supply. Free acrylic shell and fixed magnetic column, magnetic adsorption fixed installation, convenient and quick. QCC3034+PCM5102A lossless mission, lossless decoding, no loss, perfectly display the dynamics and details of the sound, high frequency without glitches, midrange is round, low frequency is powerful, good flexibility. Extremely high parameter performance: dynamic 112dB, signal-to-noise ratio 112dB, distortion -93dB, no harm without contrast. The key parts of C adopt fever capacitors, which perform well in parameters such as dissipation factor and ESR etc, improve the speed and improve the overall quality of high, medium, and low frequencies etc. Different temperature, voltage, and frequency affect the sound quality, and a good dissipation factor can reduce the impact. The small leakage current of the capacitor reduces the aging degree etc, and the low ESR reduces the high-frequency impedance and increases the dynamic response speed. type: QCC3034 Material: plastic colour: As shown Package Contents: 1 x Audio Decoder Board Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
