RAMPS 1.4:

RAMPS 1.4 is short for  RepRap Ard. Mega Shield. It is designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS 1.4 interfaces an Ard. Mega with its powerful platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on an Ard. MEGA shield for easy service, part replacement, upgrade-ability and expansion. Additionally, a number Ardulno expansion boards can be added to the system as long as the main RAMPS 1.4 board is kept to the top of the stack.
 
MEGA 2560 R3:

 
This is the new 2016 version of our Mega 2560 board that is fully compatible with the Arduino Mega 2560. It utilizes a genuine Atmel ATmega2560 microcontroller and the inexpensive CH340G USB-UART interface. 
This board continues our commitment to uncompromising quality using the best components and excellent design layout, whilst providing a stable low cost solution. It uses the CH340G to lower the cost without losing functionality or quality. 
 
A4988 stepper motor driver:

A4988 is a complete microstepping motor driver with built-in translator for easy operation. This driver can use 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 sequence tables, high frequency controllines, or complex interfaces to program. A4988 interface is very suitable for complex microprocessoris 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, under-voltage lockout (UVLO), and crossover-current protection. Special power sequencing.
 
DRV8825 stepper motor driver:

The DRV8825 stepper motor driver carrier is a breakout board for TI’s DRV8825 microsteppingbipolar stepper motor driver. The module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications. The DRV8825 features adjustable current limiting, overcurrent and overtemperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).
 
Smart LCD 2004 Controller for RAMPS 1.4, with SD card reader:

This is TEXT 20x4 Smart LCD Controller contains a SD-Card and MicroSD-card readers, stop button and rotary encoder and a simbol LCD 20x4 display (blue color).
After connecting this controller to your RAMPS board, you don't need your pc any more, the Smart LCD Controller supplies power for your SD/MicroSD card. 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 SD card.



Smart Adapter for RAMPS 1.4, for connecting to LCD controller:

This adapter need for connecting RAMPS 1.4 Shield to LCD controller (graphics or text).
