RAMPS 1.4 is designed as an extension of the Arduino Mega and can be used to control a 3D printer or CNC.

This is an expansion board design for the user’s need for a RepRap in one small package for low cost. This is an all-in-one design plug in shield which fits the necessary components for a 3D printer, while being compatible with Arduino Mega.




  • Supply Voltage : 12 V
  • Fused at 5A for additional safety and component protection
  • Heated bed control with additional 11A fuse
  • Pololu boards are on pin header sockets so they can be replaced easily or removed for use in future designs.
  • I2C and SPI pins left available for future expansion.
  • 2 stepper motor for Z axis in parallel.

Features :

  • Standard interfaces (as that of extruder)
  • Reserved GCI like I2C and RS232
  • MOSFET 3 MOSFET are apply to the heater/ fan and thermistor circuit.
  • Another 5A added to protect the component parts.
  • An 11A fuse is add to the hotbed.
  • Support 5 stepper drive board
  • The adoption of Pin Header as pololu makes it more convenient to repair or change.
  • I2C and SPI are reserve for expanding
  • All the MOSFET can be controlle by PWM
  • Use the interface of servo motor to adjust the level of printing platform automatically.
  • Adding a SD module for SD ramps module.
  • LED can indicate the status of the heater (the open and close of MOS).
  • Expandable to control other accessories.
