Review on 2x3WT class D stereo audio amplifier module GF1002 PAM8403 chip with DC 2.5-5V volume control by Adam Rymko ᠌
Great product, best quality.
Used in a homemade speaker with an old 8 ohm speaker. I took power from a USB computer, soldered it, connected the speaker to a PC, everything works. Noise at high amplification is quite normal. If you want to "clean up" the sound, think about filtering. Enough for my task, I was satisfied with the amplifier. Nuance. On the board, the input contact of the right channel is for some reason marked with the letter B, and not the letter R, be careful.
- Small size, the ability to fine-tune the gain, complete with a nut and washer for mounting the amplifier board
- At high gain, it can produce quite a loud noise.
