TCRT5000 Infrared Line Tracking Sensor Module, IR Reflectance Sensor for Smart Cars, Arduino Robots, Black White Line Detection

Feature:
Mini DC-DC step up voltage regulator with DC 2-24V input and 5V-28V output
Equipped with MT3608 voltage booster chip with high conversion efficiency up to 93%.
Widely used for storage battery, power transformers, DIY adjustable regulated power supply, industrial equipment, 5V, 9V, 12V, 28V output, etc.
MT3608 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload.
Method of use:
The module of the IN+ and – after 2~24v, adjusting the potentiometer can adjust output voltage, output voltage is greater than the input voltage
Matters needing attention:
The input voltage should not exceed the maximum input voltage
The peak current output current no more than TV university
When the module output voltage can not be adjusted, the output voltage is always equal to the input voltage.Please adjust the potentiometer counterclockwise 20 laps or more (Let potentiometer against your chest, counterclockwise turn boost)
Package Included:
5PCS MT3608 DC Voltage Regulator Board
Note:
Before the first use, the module is not powered and not connected to the load, the blue potentiometer copper head a word mouth adjustment cap, aligned with the direction of the chest, counterclockwise rotation of the potentiometer to the end of the “ta” sound, and then clockwise rotation of the potentiometer more than 30 turns, and finally connected to the power supply, using a multimeter to monitor the module’s output voltage to achieve the desired voltage
