• Supply Voltage: 12V


• Standard interfaces (as that of the extruder)


• Reserved GCI like I2C and RS232


• 3 MOSFET’s are applied to the heater/ fan and thermistor circuit.


• Another 5A added to protect the component parts.

The RAMPS 1.4 3D Printer Controller Board Arduino Mega Shield is designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an Arduino Mega with the powerful Arduino MEGA platform and has plenty of room for expansion.

RAMPS can only work when connected to its motherboard Mega 2560 and A4988/DRV8825. Owning to its stability in operation and great compatibility with the most 3D printer . The combination of Ramps1.4 + MEGA2560 + A4988/DRV8825 is becoming a mainstream of DIY 3D printer control board.
