Reprap Ramps 1.4 Shield for Arduino Mega


RAMPS 1.4:
This list is Pololu trillion rupiah , or ramps shorter. It was designed as a low-cost small package RepRap needs to fit the entire electronics . Oblique interface with the powerful MEGA platform  Mega , and have plenty of room for expansion. In the stepper drives and an MEGA shield extruder control electronics for easy maintenance , replacement parts , upgrades, capacity and expandable modular design includes plug-ins. In addition, some expansion boards can be added to the system , as long as the main ramp plate is saved to the top of the stack .
 
This board is mainly based on the Pololu_Electronics and work Tonok Adrian 's . Copper etching anti- Vick recommended method . Vick also by the work of EasyDrivers inspiration. Circuit design mainly based on the provision of initial Adrian'sPololu_Electronics Joaz RepRapSource.com pin definitions and many design improvements. Too much inspiration , advice, and from Prusajr, Kliment, Maxbots, Rick, and many other RepRap community ideas.
 
Feature
   1 It has Cartesian robot and the requirements of the extruder .
    (2) extended to control other accessories.
    3 heater / fan output and three thermistor circuit MOSFET.
    4 fusion 5A additional safety and component protection
    5 heating control extra bed 11A fuse
    6 Suitable for 5 Pololu stepper driver board
    7.Pololu board pin socket, so they can be easily replaced or removed for future designs .
    8.I2C and SPI pins left for future expansion.
    9 All the MOSFET PWM pin is hooked into versatility .
    10 . Servo connector for connection to the end stop block , the motor and the light emitting diodes. These connectors are gold-plated , rated current of 3A, very compact.
    11.SD card add - is now available from the Kliment - Sdramps
    12.LED indicate when the heater output
    13 Option 2 motors connected to the Z Prusa Mendel
