Using TPA3116 and CSR4.0 Bluetooth module. 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.
The 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.
Fully enclosed dust-proof potentiometer is adopted, which has more stable performance and more durable than ordinary potentiometer!
The use of fully shielded audio special high-current inductors ensures a clear and powerful sound. Use the latest Bluetooth version 4.0
The way to connect to Bluetooth is the same as that of ordinary devices! Search device (YJHIF)-click (YJHIFI) to connect the device-play music
