This module adapted for the arduino includes a laser diode and a 3-pin connector for a simple and quick adaptation with the Arduino. The diode is mainly used for laser toys, all kinds of level meter, instruments, stylus pen, mini LCD projector, remote listeners laser, alarm anti-theft light remote control. Light shots and different display can make the color of the image element a little different from the real object. The measurement allowed error is +/- 1-3 cm. Characteristic: - Supply voltage: 5VDC
- Connector of 3 pins:
1- GND
2- VCC
3- Light control of the laser diode
- Point mode: point facula
- Continuous output
- Operating temperature: -36 ° C - + 65 ° C
- Laser wavelength: 650nm (red)
