SainSmart RAMPS 1.4 3D Printer Starter Kit with Mega2560 R3 + A4988 for Arduino RepRap (Optical Endstop 3D Included)

Descripción

RAMPS 1.4 is a Mega Pololu Shield, or RAMPS for short, designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an 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 MEGA shield for easy service, part replacement, upgrade-ability and expansion. Mega2560 R3 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. AA4988 driver is a carrier board or breakout board for Allegro's A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection by Pololu; we therefore recommend careful reading of the A4988 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil.The optical endstop is a reliable endstop / switch solution for any type of 3D printers and other CNC and/ or 3D tools.Package Content1 x RAMPS 1.41 x Mega 2560 R35 x A4988 driver1 x USB Cable1 x RAMPS 1.4 wiring cable3 x Optical endstop with cablesNote: Download the doumentation & codes here: https://s3-ap-northeast-1.amazonaws.com/sain-amzn/20/20-011-962/3D.rar https://s3-ap-northeast-1.amazonaws.com/sain-amzn/20/ramps.rar https://s3-ap-northeast-1.amazonaws.com/sain-amzn/20/3d+lcd+software/arduino-1.0.1.rar
