MKS-GEN V1.4 3D Printer Mainboard+5Pcs DRV8825 Driver for 3D Printer Compatible with Mega 2560 R3/RepRap Ramps1.4

About MKS GEN V1.4: Features: 1. It gather 2560 and ramps1.4 on a same board, which solved the Ramps1.4 combination interface problem that easily out of order. 2. Can replace the motor driver, support 4988 drivers and 8825 drivers 3. Circuit board uses the high quality of 4 layer board,optimize heat dissipation;Ramp Is 2 layer board 4. Using special power supply chip, support the 12v-24v power input, solve the problem of Ramps voltage conversion of chip fever. 5. Accept 24V input, under the same system power can reduce the current hot bed to 1/4, effectively solve the problem of hot bed MOS tube heating 6. The firmware can use open source firmware Marlin, configuration are exactly the same with ramps1.4 can be directly replace ramps1.4 also Can be connected directly to Ramps1.4, 2004 LCD control board and the LCD board (12864) 7. Provide three 5V output, three 12V-24V output interface. About Drv8825: Heat Sink: 9*9*5mm/approx 0.35*0.35*0.2inch DRV8825: 20*15*11mm/approx 0.79*0.59*0.43inch Six different stepping resolutions: full, half, 1 / 4,1 / 8,1 / 16,1 / 32 Suitable for driving below 8.2V ~ 45V 2.5A stepper motor A simple steps and direction control interface Adjustable potentiometer can adjust the maximum output current, resulting in higher step rate Automatic current decay mode detection / selection Thermal shutdown circuit, undervoltage lockout, crossover current protection Ground short-circuit protection and load short-circuit protection Package Included: 1 x MKS GEN V1.4 5 x DRV8825 5 x Heatsink 1 x USBCable
