1.The 2560 and ramps1.4 collection on a board to solve the interfaces complicated,problem-prone fault.
2.Replaceable motor drive, the drive supports 4988 and 8825 drives, TMC2100 drive.
3. Circuit board with high-quality 4-layer, and made a special heat treatment optimization.
4.Using high-quality MOSFET, better heat dissipation.
5.Using a dedicated power supply chip, support 12V-24V power input, solve the Ramps voltage converter chip heating problem. 6.Accept 24V input,the same system power can reduced the heatbed current to 1/4,an effective solution to the hot bed MOS pipe heat problems.
7.It can be connected Ramps 1.4,2004 LCD control and 12864 LCD control directly.
8.All extra pins broken out the same as ramps1.4(AUX-1,AUX-2,AUX-3,Servos1)
