12*30mm 650nm 3.5mW Red Laser Dot Diode Module with TTL 0-15khz

Working Voltage 5.0V, red wire for 5V+, black wire commonly for 5V- and also for TTL -, 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 >100KHZ, the laser cannot be seen.
We also have this laser module of TTL 0-15KHZ for sale, please search our store for it.
