1. Integrate MEGA 2560 and ramps1.4 into one, which solves the problem that the combination interface of Ramps1.4 is cumbersome and prone to failure
2. The circuit board adopts a 4-layer board, and has been specially optimized for heat dissipation
3. Using MOSFET tube, the heat dissipation effect is better
4. Adopt special power chip, support 12V-24V power input
5. 24V input is possible, and the current of the hot bed can be reduced to 1/4 under the same system power, which effectively solves the heating problem of the hot bed MOS tube
6. The firmware can use the open source firmware MarIin, the configuration is exactly the same as that of ramps 1.4, and can directly replace Ramps1.4
7. Can be directly connected to Ramps1.4, 2004LCD control board and 12864LCD control board
