These Modules are very cheap in cost but have a great utility when you need to provide different voltage to your Arduino projects.
These are just great. They can be powered at 5v from the micro USB slot or 12v by the barrel socket. They fit perfectly on a breadboard supplying power to both the left and right strips. Voltage can be switched to 3.3v or 5v depending on your needs regardless of whether you supply 5v or 12v. Perfect for providing power for prototyping on those little breadboards. So cheap, I now have three so can leave everything plugged in.

Nice product As described Arrive on time
I have about 10 of these. They are perfect for micro-breadboarding - providing 5V/5V - or 5V/3V. Perfect for ATmega micro projects. And they are hearty too. I've accidentally shorted the output more than once - getting them very hot. And they just bounce back. And the slim footprint doesn't dominate your breadboard. Perfect !!!
This power module for Arduino with 2 private entrance is very good. Power is of two ways as possible. This is perfect and well improve my utiisation my Arduino. - Ce module de puissance pour Arduino avec 2 entrèes est de très bonne qualité. L'alimentation se fait de deux façons possible. Cela est parfait et améliore bien mon utiisation de mon Arduino.
Even though 7 ~ 12V is printed in the board, when used with a 12V power supply it gets worryingly hot and does not function properly. I have left it working for days on a 9V PSU and everything is OK. For it's price it is OK.
Really cool and versatile part - use it for my Arduino projects and it is a good way to get clear power to (fiting) breadboards. I can recommend it for its useful appearance and low price
It fits perfectly in the four vcc and gnd lines of a MB-102 breadboard. It works with a common USB charger (and a miniUSB cable) and it has a LED indicating the power. And in case of short circuit it cut off the power. Best price, very convenient for 2 power module!
Bought these for bread board projects . Have not had a chance to use yet, but looks very promising. 3 and 5 volts dc on the board without dragging down the SBC power supply.
