Use TPA3116. DAC uses Texas Instruments PCM5100
Bluetooth uses Qualcomm QCC3003 Bluetooth 5.0 chip
The power filter capacitor adopts imported 470UF/25V and electrolytic capacitor
Five-ring metal resistance is used for the resistance, and the main circuit adopts a five-ring metal film resistor with an accuracy of +/- 1%, which ensures a good signal-to-noise ratio of the whole machine.
PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tinning process to ensure good passing performance of large and small currents. First-class PCB quality.
