Review on 4-Pack 3.3V 5V FT232RL USB to TTL Serial Converter Adapter Module for Arduino by Jason Richardson

Revainrating 5 out of 5

4/4 work fine no jumpers

Four out of four work great. They didn't come with the little jumpers you need to select 5V or 3.3V operation. So make sure you find some of these, or get ready to solder the pins together.

Pros
  • Very good value for money
Cons
  • Can I add anything
