Ramps 1.4 Shield

Ramps 1.4 Shield 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.

Specification:

• 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.
