Bluetooth 5.0 product details:
1. Using original TPA3116
2. Bluetooth adopts QCC3003 Bluetooth module
3. DAC decoder chip uses PCM5102
4. Power supply filter capacitor is 3300UF/50V
5. The main circuit of electrolytic capacitor signal adopts Taiwan brand, and the main filter capacitor adopts Japanese electrolytic capacitor to ensure strong and continuous power support.
6. The resistor uses high-precision chip resistor to ensure a good signal-to-noise ratio of the whole machine.
7.PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and spray tin full process to ensure good passing performance of large and small currents.
8. With fully enclosed dustproof potentiometer, the performance is more stable and more durable than ordinary potentiometer!
9. Use high-impedance inductors for fully shielded audio to ensure sound is crisp and powerful.
10. Adopt the latest Bluetooth 5.0+DAC version
11. The way to connect to Bluetooth is the same as that of a normal device! Search device (YjHiFi)-point (YjHiFi) connection device - play music
