Description
18*45mm 980nm 30mW 60mW 120mW Infrared DOT Focusable Laser Module TTL
Output Power: 30mW, 60mW, 120mW, 200mW
Wavelength: 980nm
Working Voltage: 5.0VDC
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
