18*45mm 980nm 30mW 60mW 120mW 200mW Infrared DOT Focusable Laser Module TTL

Working Temperature: -10 centi-degree~40centi-degree

Dimensions:  ø18mm*45mm

Working current:  <300mA

TTL: 0-5V

Frequency: 0-100KHz

Red wire for + pole, black wire for - pole, yellow wire for TTL + pole.

NOTE:

1. 100KHZ high frequency--quite different with the 35khz low frequency.

2. red wire for voltage + pole, black wire for voltage - pole. black wire also for TTL - pole

3. you have to add at least 1000khz signal on the yellow wire for TTL effect. if not, you cannot get the TTL effect
