The DC-DC step-down voltage regulator board has a switched-mode voltage regulator. Current can flow through the regulator up to 2A. Input voltage is between 4.75-23V. Output voltage between 1.0-17V can be obtained by utilizing the mini potentiometer on the card according to the value of voltage applied in this range. Very easy to use and high performance, this voltage regulator card allows you to adjust your input voltages in many hobbies and robotic pros.
There is an empty pin on the regulator board for connection of input and output voltages. In this way you can solder the header of the man and integrate it into the breadboard or different cards or you can use it by soldering the cable directly.
In card applications, the input voltage must always be higher than the output voltage. The IN + positive supply input on the card is IN- ground, the positive output voltage is OUT +, and the ground output is OUT-.
