DESCRIPTION
3D Printer Controller RAMPS 1.4:The RepRap Ar duino compatible ME GA Pololu Shield, or RAMPS for short. It is designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an Arduin o compatible Me ga with the powerful Arduin o compatible ME GA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on an Arduin o compatible ME GA shield for easy service, part replacement, upgrade-ability and expansion. Additionally, a number of Arduin o expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack.Features:USB type B receptacle.SDcard add on available.Fits 5 Pololu stepper driver board.Expandable to control other accessories.Heated bed control with additional 11A fuse.Option to connect 2 motors to Z for Prusa Mendel.I2C and SPI pins left available for future expansion.It has provisions for the cartesian robot and extruder.All the Mosfets are hooked into PWM pins for versatility.3 mosfets for heater / fan outputs and 3 thermistor circuits.Fused at 5A for additional safety and component protection.Pololu boards are on pin header sockets so they can be replaced easily or removed for use in future designs.Servo style connectors are used to connect to the endstops, motors, and leds. These connectors are gold plated, rated for 3A, very compact, and globally available.Me ga2560 R3:Fully compatible with original Arduin o Me ga2560 R3, with this product, you are able to use all the Ar duino open source platform to create or learn interactive objects.Compared with UNOR3, this is with main Chip ATme ga2560, with more I/O Pins, and additional 10 PWM output, of course, the EEPROM is also with larger space.A4988 StepStick Compatible Stepper Motor Driver Module:
A4988 is a complete microstepping motor driver with built-in translator for easy operation. This product is available in full, half, 1/4, 1/8 and 1/16 step modes operate bipolar stepper motors, output drive capacity of up to 35 V and +- 2 A. 
A4988 includes a fixed off-time current regulator, the regulator in slow or mixed decay modes. A4988 converter is the key to the easy implementation. As long as the "step" input inputting one pulse drives the motor one microstep. There are no phase seq uence tables, high frequency control lines, or complex interfaces to program. A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened.
In the micro-step operation, A4988 chopping control inside automatically selects the current decay mode (Slow or Mixed). In mixed decay mode, the device is initially set to a fixed downtime in some fast decay, then the rest of the slow decay downtime. Mixed decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption. Internal synchronous rectification control circuitry is provided to improve the pulse-width modulation (PWM) operation power consumption. Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO), and crossover-current protection. Special power sequencing.
A4988 surface mount QFN package (ES), a size of 5 mm x 5 mm, nominal overall package height of 0.90 mm, with an exposed pad for enhanced thermal dissipation. This package is Pb (suffix-T), with 100% matte tin leadframe plating.
Note: PCB Colors May vary
LCD 2004 Graphic Smart Display Controller:This full graphic Smart Controller contains a SDcard reader, an rotary encoder and a 128 x 64 dot matrix LCD display. You can easy connect it to your Ramps board using the "smart adapter" included.After connecting this panel to your Ramps you don't need your pc any more, the Smart Controller supplies power for your SDcard. Further more all actions like calibration, axes movements can be done by just using the rotary encoder on the Smart Controller. Print your 3D designs without PC, just with a g-code design stored on the SDcard.Package includes:1 x 3D Printer Controller RAMPS 1.4 Board1 x Me ga2560 R35 x A4988 StepStick Stepper Motor Driver Module1 x LCD 2004 Craphic Smart Display Controller1 x USB Cable
