Review on πŸ”Œ High-Quality 20 Pieces 3 Pins AMS1117-3.3 DC 4.75V-12V Voltage Regulator Step Down Power Supply Buck 800mA Module - Reliable and Efficient by Derrick Milkie

Revainrating 5 out of 5

Great deal for 20 pieces; everything seemed to work fine

Tested all 20 voltage regulators with a proven 5V source and Vout fluctuated between 3.26 and 3.34 volts. Only one part was at 3.34v, with most being just under 3.3v and some being near perfect. I haven't tested how much current they can safely carry without a heatsink, or if they can handle 800mA as stated in the description.

Pros
  • Absolutely Awesome!
Cons
  • Keep quiet
