445nm High-Power 5.5W NUBM0A 0E 0F NUGM03 04 06 Blue/Green Light Drive Circuit

5.5W NUBM0A 0E 0F 44 NUGM03 04 06 High power Blue and Green Light Drive Circuit 4.5A Constant Current with Slow Start and Step-down Three speed Dimming



Specifications:

Circuit control: 5V step-down circuit, constant current output, ensuring stable optical output of 5.8-12V power supply

Size specification: 12 * 22mm (width * length)

Reverse protection: Unique reverse protection design, no need to worry about the battery burning out instead of discharging

Pin definition: A solder pad designed specifically for 445nm driver boards, you only need to naturally solder it in a triangular arrangement according to the pin positions

Polarity definition: The module shell is positive, and the tail pad is negative. Please refer to this link for welding instructions





Warning:
To ensure safety, it is recommended to use imported two 3.7V lithium batteries with protective plates (16340, 186, 501, 4500, and 18500 power supply). Do not use inferior battery cells, as dual lithium requires high internal resistance capacity and discharge performance of the battery cells. It is particularly prohibited to use cylindrical lithium batteries with three or more sections without protective plates. You can directly use 6-30V DC power supply, or use two string and three string polymer lithium batteries. Polymer is currently the safest among all lithium batteries.
