The EGS002 driver board works well— the sine wave output is clean. The soldering points are a bit small, but with careful handling, I was able to connect everything properly.
I used this ZK-AS21 amplifier module for my home speaker system, and it transformed the audio experience. The bass is rich and powerful, no issues with installation at all. Highly recommend!
This EGS002 SPWM driver board produces a clean pure sine wave. The 12Mhz oscillator is stable, and it works perfectly with 5V power. Great for my inverter project.
