Quick Overview

Based in Wuhan, Central China Hubei Province, Lilly Electronics is engaged in fabrication, sales and R&D of consumer electronics maninly in the industry of Laser, IC and LED! You are welcome to visit us for culture exchange and mutrual business development and progress.


Operating Voltage: Input 3-4.2V
Output Voltage: 3V or less
Dimensions: 10*20mm
Thickness: 1.0mm
1. Circuit control: external MOS, constant current output
2. Power adjustment: Remove the 1206 package resistor on the board to reduce the output current
3. Reverse connection protection: unique reverse connection protection design, careless, you don't have to worry about battery burning instead
prompt: 1. If you are driving a 300mW 638nm diode, you only need to remove the R030 resistor. If you are driving 500mW or 700mW, you only need to remove the
above two R100 resistors.
2. This board can also be used for 808nm and 660nm laser tube driving, but only for lead wire soldering. For example, for 808nm 300mW with 1 ohm resistor.
3. It is recommended to use 3.7V lithium battery (16340, 18650, 14500 and 18500 power supply), or directly use 5V DC power supply.
Pin Definition: The pad designed for 300-700mW 638nm pin, you only need to be naturally welded according to the triangle of the pin.
