1.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 package for low cost. RAMPS interfaces an Mega with the powerful MEGA platform
and has plenty room for expansion. The modular design includes plug in stepperdrivers and extruder control electronics
on an MEGA shield for easy service, part replacement, upgrade-ability and expansion.
2.Mega2560 is an ATmega2560 as core microcontroller development board itself
has 54 groups digital I / O input / output terminal (14 groups do PWM outputs), 16sets 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.
3.Large screen: 12864LCD.
4.A4988 StepStick Compatible Stepper Motor Driver Module.
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 stack.
This 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.
Large screen: 12864LCD
1.Integration for SD card in the back, after slicing the file into the for SD card,
you can select the corresponding files on the LCD.
2.The board has encoder, can be achieved parameter adjustment, and the file selection print!
3.The ramps can be Plug-and-Play, but it need to modify the firmware to support.
A4988 StepStick Compatible Stepper Motor Driver Module
A4988 driver is a carrier board or breakout board for Allegro's A4988 DMOS Micro stepping 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.
