Generic 2.1 Channel Bluetooth Power Amplifier Board TPA3116 2X50W+100W Card

Features: 1. Using original TPA3116 chip
2. The main circuit of the electrolytic capacitor signal adopts 470uF/25V*8, which ensures strong and continuous power support.
3. The resistor adopts high-precision chip resistor, which ensures a good signal-to-noise ratio of the whole machine.
4. The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and the whole process of spraying tin to ensure good passing performance of large and small currents. Top-notch PCB quality.
5. Using fully enclosed dust-proof potentiometer, the performance is more stable and more durable than ordinary potentiometers. The red ring high current inductor is used to ensure the sound is clear and powerful.
