Package include: 1x 3 axis GRBL control board V3.4 1x USB cable Specification: Connection: USB (USB-CH340) Software: GRBL controller, UniversalGcodeSender Input voltage: 12-24V Master chip: atmel 328P (arduino nano) Spindle drive chip: MOSFET (recommendation 24V, current : within 10A Spindle PWM speed: Support Support stepper motor: 12V, maximum current of 2A or less is recommended within 1.5A and additional heat. (Any stepper motor 42, 57) Power Interface: 5.5-2.5mm DC interface Advantage 1.add the outer casing: protect control board in transit,to avoid short circuit problem during use; 2.add the power button switch 3.Cancel the drive module,use integrated imported stepper motor drive,with short circuit protection,and integrated heat dissipation aluminum alloy; 4.Add the fan port to force heat dissipation; 5.add offline recognition,can insert offline modules and computers at the same time.Offline will automatically identify if there is computer control. 6.Enhanced spindle drive,can support 20000rpm spindle.support more powerful spindle. 7.Improved USB interface: The original USB interface is patch soldering, transport collision and improper use, easy to drop, now changed to plug-in, very strong 8.The spindle drive increases the optocoupler isolation, which makes the control board generate less heat, and the spindle speed adjustment is more linear and safer.

• New functions: Add 2-pin emergency stop button port,probe port,XYZ limit port and add the power button switch
• Applications: The control board can be used with the 1310,1610-PRO, 3018,3018-PRO and 3018-PRO MAX etc engraving machines
