Description:
This amplifier module is based on the LM386 operational amplifier which is a high-gain, frequency compensated operational amplifier designed to operate from a single power supply over a wide range of voltages. It is used in conventional operational amplifier circuits that need to be operated from a single power rail.
Features
- On-board LM386 Chip
- Gain= 200.
- On-board speaker wiring block.
- On-board 10K variable resistor, you can adjust the volume with it.
- On-board power indicator.
- The chip pin leads, can be directly input audio signal
- Operating voltage: 5 ~ 12V
- Size:41 x14 mm
