Review on πŸ”Š HiLetgo 2pcs TDA2822M DC 1.8-12V 2.0 Channel Stereo Amplifier Mini AUX Audio Amplifier Board Module AMP for Arduino: Boost your audio experience with this versatile amplifier module! by Michele Rutland

Revainrating 5 out of 5

well made and super plug.

I am using this as a quick way for a group to hear my Crystal Radio. It has a very high input impedance and if you change the resistor divider at the input of the IC you get a much higher gain. I connected the output of one to the input of the other for even more amplification. Add a small speaker and a 9V battery and add them to the crystal set.

Pros
  • Certified
Cons
  • Cord is shorter than other picks
