A very handy power supply to connect to a breadboard with double power rails (standard plates). This module can be switched on and off by means of a push button. It also has jumpers on both sides that can be adjusted independently of each other. For example, you can set a voltage of 3.3 V on the left while setting 5 V on the right.
|Output voltage||3,3 V - 5 V|
|Input voltage||6,5 V - 12 V|
