1. Onboard LM358 chip
2. Design of a 100x gain circuit
3. Onboard 10K adjustable resistor with adjustable amplification factor
4. Onboard power indicator light
5. The main pins of the chip have been led out and can directly input and output signals
6. Working voltage: DC 5V～12V
The module is suitable for low voltage operation, for example, it can amplify the amplitude of a sine wave from 0.042V to 4.16V (about 100 times);
The signal generator outputs the sine wave signal to the module, and then adjusts the potentiometer on the module to amplify the sine wave amplitude (the maximum amplification factor is 100 times), and the amplified signal is displayed through the oscilloscope;
