Description: 2560 and ramps1.4 set on a board, to solve complicated Ramps1.4 combination of interfaces, the problem of failure prone. The circuit board with high-quality 4-layer, heat and made a special optimization; ramps are 2 shelves. Uusing high-quality MOSFET, and better heat dissipation. Using a dedicated power chip, support 12V-24V power input, the voltage converter chip to solve the heat problem Ramps. Can accept 24V input power under the same system can be hot-bed current is reduced to 1/4, an effective solution to the hot bed MOS pipe heat problems. The firmware can use open source firmware Marlin, ramps1.4 identical configuration and can directly replace Ramps1.4. Can be directly connected to the control panel and 12864LCD Ramps1.4,2004LCD control panel. Reserved for motor pulse and direction output ports for easy plug-in high-current To add a large current (eg 2A, 5A) motor drive circuit. Reserved Ramps1.4 on Servos, AUX-1, AUX-2 interface that provides three 5V output, three 12V outputs. Support A4988 DRV8825 driver. Specification: Material: PCB Size: Approx. 142*85*20mm USB cable length:500mm Package Includes: 1x Control Board 1x 50cm USB Cable
