NEW Mega2560 + A4988 + RAMPS 1.4 3D Printer KIT For Arduino RepRap

Product Features:
1. Sainsmart RAMPS 1.4
It is a Mega Pololu Shield, or RAMPS for short,designed
to fit the entire electronics needed for a RepRap in one
small paage for low t. RAMPS inteaces an Mega with
the poweul MEGA platform and has plenty room for
expansion. The modular design includes plug in
drivers and extruder control electronics on an MEGA
shield for easy service, part replacement, upgrade-
ability and expansion. Additionally, a number of
expansion boards can be added to the system as long as
the main RAMPS board is kept to the top of the sta.
2. Mega 2560
Mega2560 is an ATmega2560 as core microcontroller
development board itself has 54 groups ital 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
external writer. Suly part of the optional USB power,
or as an external power using the AC-to- adapter and
battery. This development IDE inteace is based on
open-source princles, allows you to free download for
use in project work, school teaching, motor control,
interactive works.
3. Sainsmart A4988 driver
This product is a carrier board or breakout board for
Allegro's A4988 DMOS Microsteing Driver with Translator
and Overcurrent Protection by Pololu; we therefore
recommend careful reading of the A4988 datasheet before
using this product. This motor driver lets you
control one bolar motor at up to 2 A output
current per coil.
