-== Important Notice ==
-At present, all laser modules of NEJE will pass rigorous aging tests to ensure no attenuation of power and ensure that each radiator can control the temperature within the standard range for a long time. It can be used continuously without any time restrictions. The cheap lasers bought on the market do not have diode caps. NEJE has key core technology to control the effective life of the laser diode to 10,000-20000 hours, and promises a 2 year warranty! If your laser have  problems, You can get it for free from the store you purchased, or contact the official service channel：service.nejetool.com
-The 20W lens has been updated. You don’t need to purchase lens to replace it. The new lens can adapt to engraving and cutting at the same time.
+Compatible with master 2/2s 3, NEJE 2S/3 plus, NEJE 3 Pro, NEJE 2S/3 Max machines
+With adapter([[https://wiki.nejetool.com/doku.php?id=laser_tester_v1|laser pwm tester ]]/ [[https://wiki.nejetool.com/doku.php?id=laser_switch_board_v1|laser switch board ]]) board, support 3d printer, cnc laser machine, other brand laser cnc machine, arduino project.

+TTL/PWM: TTL = PWM, input 3.3V~12V to turn on laser module, conect to GND to turn off laser module.
+Temperature: do not connect, please ignore.
+Connect 12V and GND pin to 12V power, ensure the power adapter is sufficient, 5A is recommended.
+Connect TTL/PWM pin to your control board PWM output pin.

-===== interface =====
-If you don't need temperature sensing, you don't need to connect, you can use 3pin control directly, this is that you need to make a little modification to the line.   3PIN:（12V-GND-TTL）or   4PIN:（12V-GND  +  TTL-GND）

 If the inside of the lens is stained with dust or smoke, it may cause the lens to break, because the high-power laser will cause the lens surface to crack.
-===== Warranty =====
-The NEJE module provides a 2-year warranty. The lens is not covered by the warranty. If you disassemble the module, it will no longer be covered by the warranty. If there is a quality problem with your module, please contact the customer you purchased.
