Specification: Item Type: Laser Engraver Control Board Material: Resin Input Voltage: 9V-24V 8A Output of Each Axes: 4988 module ≤1.5A, 8825 module ≤2A Spindle Output: ≤6A (9V-24V) Laser Output: PWM Output Power: Support Adjustment Connection Method: USB Power Interface: DC5.5-2.1 Package List: 1 x Control Board 1 x Cable Note: 1. Do not turn on the power on after receiving the goods, so as not to cause unnecessary losses to you. After connecting the USB cable, the motherboard can be tested, and the corresponding indicator lights will be displayed during the operation. 2. When installing the stepper motor drive module, please pay attention to the direction of the module (to match the characters on the bottom of the board), if you insert it in reverse, the main board will be burned. 3. Check whether the motor is within the driving power. For motors with a driving capacity of less than 1.5A, the peak current is 2A. The 8825 drives motors with a capacity of less than 1.7A, with a peak value of 2.5A. 4. Repeatedly check that the wiring is correct before powering on, otherwise the motherboard will be burned immediately after power on. Package List 1 x Control Board 1 x Cable
