Integrated 2560 and Ramps1.4 to one PCB, more easily cabling and stable
Using High-quality 4-layer PCB and Marlin firmware, the same configuration as Ramps 1.4
Using a dedicated power supply chip, support of V-24 V
Accept 24v input, reduce the heating bed current to 1/4, effectively solve the MOSFET heat problem
Available to connect the external large stepping drivers, keep Ramps 1.4 servos,AUX-1 and AUX-2 interface, provide three 5Voutput and three 12Voutput interfaces
