Parameter:
Wavelength:445nm 447nm 450nm
Adjustable Current: 300mA-2A
Circuit Control:5.5V Boost Circuit
Recommended working voltage: 3.7V lithium battery (16340,18650,14500,18500 power), or directly using a 5.5V DC power supply

Size:9x20mm
PCB color: yellow or Green (Randomly ship)
Reverse Polarity Protection: None

Features:
1. “C1” “C2” indicates the mark used for the patch when making the driver board. For example, what component is used of c1, and correspond the bom table.

2. Answer the positive and negative of the power supply:
①The front end of the board has a row of small holes (6pcs), the positive “+” can be welded with any small hole;
②The negative “-” and the “LD-” are soldered in the same position;
if assemble the outer housing, the housing is the negative “-” (just need to solder the power supply +, then the negative “-” is directly attached to the housing)
