Voltage DC 1.8V 3V 5V 6V 12V 2A Motor Speed Controller PWM Adjustable Switch with LM2596S High-Power Step-Down ule

2 pcs Electronic Accessories:1 x LM2596S high-power step-down ule & 1 x motor speed controller
With power indicator; With a voltmeter display, the use of microprocessors, voltmeter error +/- 0.05V, range 0 ~ 40V. (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage of 4V or more).
Contact the right button to toggle the measurement input or output voltage, and the indicator shows which circuit voltage is being measured and save the settings, even if the power is turned on again.
The voltmeter can be turned off, when you do not need to Contact the left button can be easily achieved.
With terminal blocks, no soldering iron can also be used easily, and retain the wire connection point.

Note: This item, the electrical machine can not afford the continuous current more than 0.5 A, such as 755 electric machines and children's carobile.
The motor speed controller is equipped with a self recovery fuse 2A and a power-on LED light.
It can easily have a continuous current of 2A to your DC motor or other DC load.
With the recovery backup (will automatically disconnect the automatic recovery after cooling, when the current becomes too large.)
