• 2pcs Two-Speed 1W 1 3W 445/520nm Dual Lithium Laser Driver Circuit Notice: This motive force board has 1W /1 /3W 445/520nm , please be aware the wavelength and gear you wish when purchasing, thanks Product Description:Circuit control: 5V step-down circuit, fixed current output, to ensure that the 5 energy delivery is secure after light output Output current: The default is 1 current, simply appropriate for 2W blue mild and 1W 520nm green mild pressure Output mode: the 1st instruments is long bright, the second one tools is slow flashing 8Hz Dimensions: 17*17mm (diameter*height) Reverse connection protection: Unique contrary connection defense design, don&;t fear about burning the board when the battery is discharged Pin Definition: Circuits designed for prime power blue and green mild Polarity definition: the spring is attached to the superb electrode of the battery, the outer ring pad is negative, the output is attached to the laser tube, the pink line is positive, and the blue line is negative Warning: In order to assure safety, it's strongly commended to apply two imported 3 lithium batteries with conserving plates (16340, 18650, 14500 and 18500 calories supply), do not use inferior batteries, due to the within resistance prospective and discharge functionality of double lithium batteries. The standards are high, and it is particularly forbidden to apply cylindrical lithium batteries with 3 or extra sections with out protecting plates. Maybe many peers often use three sections with none explosion accidents. If three sections are used, one among them has a enormous within resistance, instantaneous discharge, and over-discharge. , And all of the step-down chips start paintings at 5, even though there may be undervoltage protection, it's going to not help, the circuit is out of control, it's going to straight end in a short circuit and an explosion, the ability of the metal shell battery is very large, of course, any such The likelihood is rarely large, yet as lengthy as it happens, the consequences are unimaginable! You can immediately use 6-30V DC energy delivery for energy supply, or use two-string and three-string polymer lithium batteries. Polymer is today the most secure among all lithium batteries. Package: 2pcs Two-Speed 1W /1 /3W 445/520nm Dual Lithium Laser Driver Circuit
