General:

• This small driver board will drive many of the solid state green laser modules currently on the market as well as higher powered red diodes.
  
• Available in 1.5 A output (DC PCB)  or  150 mA output (DC PCB-2)
  
• Heat sinking is CRITICAL for correct operation. An option is TE cooling of the laser module. This will increase module life and the output power of the module will be more consistent than if the module free runs at ambient temperature.

Below is a simple hook up diagram:

1 mA of drive current = 0.1 mV between test points (TP1 +, and TP2 -). 
For example, 50 mV across TP1 and TP2 means that 500 mA of drive current is going through the diode.
For DC PCB-2: 1mV on Test Points = 1 mA of Drive Curent.

Notes:

Always wear anti-static wrist band on mat when handling raw diodes.

Hook up the laser diode first before applying power to the PCB, or laser diode damage could occur. GND (NEGATIVE) Input and CATHODE Output are common. Careful, because many diodes have a Positive Case (ANODE). Input is REVERSE POLARITY PROTECTED. Transistor can be heat sunk to metal body if desired- Transistor Body is ISOLATED

It is also required that the laser module have a  sufficient heat sink as well.

An option is TE Cooling of the laser module. This will increase module life and the output power of the module will be more consistent than if the module free runs at ambient temperature.

This board can also power TE Cooler elements. This circuit board is a great low cost alternative to high priced TE Cooler controller boards.
