Specifications:

Circuit control: 12V step-down circuit, constant current output (current and voltage are adjustable)
Output: Max 4A
Scope: 3W-4.5W 405/445/450 / 520nm red and green blue and other laser drive power
Size: 32 * 50.5mm (width * length), component height includes aluminum base 20mm
Input voltage: 8-14V
Slow start time: 60S (due to a minute delay, in the debugging, please do not look directly at the optical port, so as not to damage the eyes, remember !!!)
TL modulation instructions: 0-5V voltage signal (0 is off, 5 is open, the frequency determines the laser light flashing speed)
