Product Description:

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 stepper

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 stack.

2. Mega 2560

Mega2560 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. 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.

3.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.

4.A4988 Stepper Motor Driver

1.Simple step and direction control interface;

2.Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step;

3.Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated;

4.Voltage to achieve higher step rates;

5. 3.3 and 5 V compatible logic supply

6.Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay);

7.Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection;

8.Short-to-ground and shorted-load protection.
