Input voltage: 7~12 V DC or USB 5V power supply;
Output voltage: 3.3V / 5V, switchable;
Maximum output current: less than 500 mA, onboard 500mA resettable fuse;
Two ways independent control: one way output 5V, the other one output switchable 5V or 3.3V.
Application: Very suitable for Arduino DIY projects with MB102 breadboard, Easy to use.
