About MKS-GEN Mainboard:
1, Assemble 2560 and ramps1.4 on a board to solve the problem of complex interface and easy failure of the Ramps1.4 interface.
2. Replaceable motor drive, support 4988 drive and 8825 drive, TMC2100 drive, s109 drive
3, Reserved external drive signal, can be connected to the external drive to drive 57, 86 motors.
4, The use of high-quality MOSFET tube, heat dissipation better, to ensure long-term stability.
5, The use of dedicated power chip, support 12V-24V power input, to solve the Ramps voltage conversion chip heating, inadequate power supply problem.
6, 24V input can be accepted. Under the same system power, the hotbed current can be reduced to 1/4, effectively solving the problem of heat pipe MOS heating.
7, The use of open source firmware Marlin, configuration and ramps1.4 exactly the same, can directly replace Ramps1.4.
8, Can be directly connected to the 2004LCD display and 12864LCD display, can support TFT28, TFT32 touch screen.
9. Reserve the motor pulse and direction output port to facilitate the external high current to be connected to a large current (such as 2A, 5A) motor drive circuit.
10. Retain the Servos, AUX-1, and AUX-2 interfaces on Ramps1.4, providing three 5V outputs and three 12V output interfaces.

About A4988 drive:
1, Suitable for driving the stepper motor below 8V-35V 2A.
2. Only a simple step direction control interface.
3, Fve different stepping modes: full, half, 1/4, 1/8 and 1/16.
4, The adjustable potentiometer can control the maximum current output, thus achieving a higher step rate.
5, Automatic current attenuation mode detection / selection.
6. Overheating shutdown circuit, under voltage lockout and cross current protection.
7, Grounding short circuit protection and load short circuit protection.
About MOS MINI Module:
1. Excellent performance MOS tube (nominal maximum current 280A).
2, Iarge heat sink, the maximum current can be up to 30A.
3, You can directly use the hotbed output signal control of Ramp1.4 and MKS series motherboards.
4, Can use 5-24v digital signal control
