RAMPS 1.4 SHIELD for Arduino Mega

RepRap Arduino Mega Shield, or Ramps 1.4 for short. It is designed to fit the entire electronics needed for a RepRap 3D printer control. This board is semi populated and the Pololu stepper drivers is NOT included.

Features

• 3 x 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 5 Pololu stepper driver board (Not included)
• 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.
• All the Mosfets are hooked into PWM pins for versatility.
• Servo style connectors are used to connect to the endstops, motors, and leds.
• SD Card add on available
• LEDs indicate when heater outputs are on
