Geekcreit® 3D Printer RAMPS 1.4 Controller + MEGA2560 R3 + A4988 With Heat Sink Kit

We will default sending carton package to replace the plastic box, but there may some stocks are still packaging with plastic box, please note about this before you buy it. Features:RAMPS 1.4The RAMPS 1.4 board is designed to fit the entire electronics needed for a RepRap in one small package for low cost.RAMPS interfaces an Arduino Mega with the powerful Arduino MEGA platform and has plenty room for expansion.The modular design includes plug in stepper drivers and extruder control electronics on an Arduino MEGA shield for easy service, part replacement, upgrade-ability and expansion.Additionally, a number of Arduino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stackMega 2560 R3 boardMega is an ATmega2560 as core microcontroller development board itself has 54 groups digital I / O input / output terminal (14 groups do PWM outputs), 16 sets of simulation than the input side, group 4 UARTs (hardware serial ports), using the 16 MHz crystal oscillator.With the bootloader, download the program directly via USB without having to go through other external writer.Supply part of the optional USB power, or as an external power using the AC-to-DC adapter and battery.Arduino development IDE interface is based on open-source principles, allows you to free download for use in project work, school teaching, motor control, interactive worksA4988 driverThis is a carrier board or breakout board for Allegro's A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection by Pololu;This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coilPackage included:1 x RAMPS 1.4 Board1 x Mega 2560 R3 Board5 x Soldered A4988 driver5 x Heatsink for A4988 driver1 x USB cable20 x Jumper Cap
