650nm 3.5mW Red Laser Dot Module w/TTL 0-15KHz

描述

Parameter Wavelength：650nm Output Power：3.5mW Working Current： Working Voltage：5.0VDC Duty Cycle：5 minutes on, 1 minute off TTL frequency：0-15KHz TTL modulation Voltage：0-5V Off low, high open, normal status open Dimensions：12mmx30mm Detail: red wire for 5V+, black wire commonly for 5V- and Yellow wire for TTL +. If you only connect its black wire and red wire, the laser would not work, you also need to connect its yellow wire (TTL+) to 5v+. When the TTL signal is connected, the higher the frequency is , the less brighteness the laser will have. when it is >15KHZ, the laser cannot be seen. Package: 1 x 650nm 3.5mw Red Laser Dot Module w/TTL 0-15KHz
