Description:
Bluetooth uses CSR8675 5.0 chip, DAC uses PCM5102, and operational amplifier uses JRC5532 (other dual operational amplifiers can be replaced freely).
The electrolytic capacitor adopts 220UF/25V electrolytic capacitor, which guarantees strong and continuous power support.
High precision patch resistor is selected to ensure good signal-to-noise ratio of the whole machine.
PCB uses 1.6mm thick double panel, 2.0A thick copper, tin spraying process to ensure good passing performance of large and small currents. First-class PCB quality.

Specification:
PCB size: 75.5*66.5*19MM high
Voltage: DC 12V (internal + external-)
Bluetooth 5.0 Receiving Distance is about 10 meters
Package Includes:
1Piece CSR8675 Bluetooth 5.0 Board
