Description

EU-40 is a small and inexpensive driver board for continues wave (CW) operation of blue and green laser diode. The

Automatic Current Control (ACC) circuit allows for a laser diode current of up to 200 mA, adjustable by means of a

potentiometer. EU-40 utilizes an up-converting current logic, and can be driven off a 3 VDC supply voltage. The laser

diodes output power is independent from the drivers supply voltage.
