Sainsmart 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 Arduino MEGA shield for easy service,
part replacement, upgrade-ability and expansion.
Sainsmart 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. 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 works.
Sainsmart A4988 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.
