RAMPS RepRap Shield for Arduino Mega

Driver to connect stepper motors in the kit with additional elements needed to run a 3D printer. The system is compatible with Arduino Mega 2560. It requires five modules with driver A4988, to work. In addition to these elements, Ramps 1.4 enables connecting mechanical or optical limit sensors, devices to control the injection of plastic and an LCD display,SD memory card reader and Bluetooth module.

The Ramps 1.4 module is controlled through the Arduino Mega 2560 platform, which, thanks to its versatility, makes it easy to expand the system. Motors are controlled by popular, chips A4988, with maximum current up to 2 A per motor. Arduino Mega 2560 and the A4988 drivers are not included in the package. They can be purchased separately in our store.

Features:

• Standard interfaces (as that of extruder)
• Reserved GCI like I2C and RS232
• MOSFET 3 MOSFET are applied to the heater/ fan and thermistor circuit.
• Another 5A added to protect the component parts.
• An 11A fuse is added 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 reserved for expanding
• All the MOSFET can be controlled 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).
• 2 stepper motor for Z axis in parallel.
• Expandable to control other accessories.
