Description

780nm 1mw Infrared Laser Module 5V TTL near infrared laser module
Module size: 8mm diameter, length 13mm

1.Red wire power “+”
2.Black wire : power “-”
3.The yellow wire is connected to the positive pole of TTL modulation, square wave signal input port, 0-10KHz
4.Constant power circuit control
5.High voltage on and low voltage off. Normally off, when there is no signal input.The yellow wire and red wire can be connected to the positive electrode of the power supply to turn on the laser.
6.780nm is invisible light to human eyes, which can be seen through infrared equipment, and there is a small amount of red burst
8.Do not work for a long time if there is no extra heatsink.
