Description:

• It is a RAMPS for short, 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 room for expansion. 
• The modular design includes plug in stepper drivers and extruder control electronics on an Arduino MEGA shield 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.

Specification:

• Has provisions for the cartesian robot and extruder;
• Expandable to control other accessories;
• 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 for 5 Pololu stepper driver board;
• I2C and SPI pins left available for future expansion;
• All the Mosfets are hooked into PWM pins for versatility;
• Servo style connectors are used to connect to the endstops, motors, and LEDs. These connectors are gold plated, rated for 3A, very compact;
• SD Card add on available
• LEDs indicate when heater outputs on
• Option to connect 2 motors to Z for Prusa Mendel

Package Includes:

• 1 x Ramps 1.4 Module
