NEJE has a variety of laser modules, but the control methods are the same
12V: Power input
GND: Power ground and signal ground(pwm ground)
TTL/PWM: TTL = PWM, input 3.3V~12V to turn on laser module, connect to GND or not connect to turn off laser module
Temperature: Communication interface. For DIY players, please ignore this pin
About Power
Connect 12V and GND pin to 12V power, ensure the power adapter is sufficient, 12V 5A is recommended, What Power Adapter Should I Use?
About PWM
Connect TTL/PWM pin to your control board PWM output pin
NOTE: DON’T FORGET connect GND to your control board.
