RAMPS 1.4 3D Printer Controller with 5Pcs DRV8825 Driver with Heat Sink Kit

This Kit includes RAMPS 1.4 3D Printer Controller and A4988 Driver with a heat sink.

The RAMPS 1.4 is an all-in-one design to fit the necessary components for a 3D printer into one plug-in shield for an Arduino MEGA. The plug-in shield design includes plug-in stepper drivers and extruder control electronics sockets for easy service, part replacement, upgrade-ability, and expansion.

The DRV8825 driver carrier is a breakout board for TI’s DRV8825 micro-stepping bipolar stepper motor driver. The DRV8825 features adjustable current limiting, over-current, and over-temperature protection, and six micro-step resolutions (down to 1/32-step)

Features:

• The RAMPS 1.4 card is designed to fit all the electronics needed for a RepRap
• RAMPS interfaces a Mega with the powerful MEGA platform and has plenty of room for expansion
• LEDs indicate when the heater outputs on.
• 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 an additional 11A fuse.
• Shield has on pin header sockets so they can be replaced easily or removed for use in future designs.
• I2C and SPI pins are left available for future expansion.
• All the Mosfets are hooked into PWM pins for versatility.
• Servo-style connectors are used to connect to the end stops motors and LEDs.
• These connectors are rated for 3A, very compact, and globally available.
• LEDs indicate when the heater output is on.
