RAMPS 1.4 Controller Expansion Board

The RAMPS 1.4 (RepRap Arduino Mega) is an all-in-one design to fit the necessary components for a 3D printer into one plug in shield and interfaced with an Arduino MEGA. It is a clean, compact way to integrate all the systems into a compact enclosure in a mountable format. Used widely for making DIY 3D Printers. The plugin shield design includes the plugin stepper drivers and extruder control electronics for easy service, part replacement, upgrade-ability, and expansion. Additionally, a number of Arduino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack.

RAMPS can only work when connected to its motherboard Mega 2560 and A4988/DRV8825. 

Features:

• 3 MOSFETs for heater/fan outputs and 3 thermistor circuits.
• Fused at 5A for additional safety and component protection
• Heated bed control with additional 11A fuse
• Fits 4 x A4988 stepper driver boards
• Expandable to control other accessories.
• Boards have pin header sockets so they can be replaced easily or removed for use in other designs.
• I2C and SPI pins are available for expansion.
• All the MOSFETs are hooked into PWM pins for versatility.
• Servo style connectors are used to connect end stops motors and LEDs.They are rated for 3A, very compact, and globally available.
• SD Card add-on available
• LEDs indicate when heater outputs on
• Option to connect 2 motors to Z for Prusa Mendel
• Reserved GCI like I2C and RS232
• Supports 5 stepper drive board
• The adoption of Pin Header as Pololu makes it more convenient to repair or change.
• LEDs can indicate the status of the heater (the open and close of MOS).
• 2 stepper motor for Z-axis in parallel.

Package Includes:

• 1 x RAMPS 1.4 3D Printer Controller Board
