keyestudio 3D Printer Cnc Kit for Arduino RAMPS 1.4 + Mega 2560 + 5x A4988 + 20×4 LCD Controller with Adapter Compatible for Arduino and RepRap



Price: $39.99

1. Keyestudio Mega 2560 board
Works as original Mega 2560, 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, 16 MHz crystal oscillator.

2. LCD 2004 Smart Controller

Easy connect it to your Ramps board using the “smart adapter” included. After connecting this panel to your Ramps you don’t need your pc any more, the Smart Controller supplies power for your SD card. Further more actions like calibration, axes movements can be done by adjusting the rotary encoder on the Smart Control panel.

3. RAMPS 1.4
A Mega Pololu Shield
3 mosfets for heater / fan outputs and 3 thermistor circuits;
Fused at 5A for additional safety and component protection;
Heated bed control with additional 11A fuse;
Fits 5 Pololu stepper driver board;
Pololu boards are on pin header sockets so they can be replaced easily or removed for use in future designs;
I2C and SPI pins left available for future expansion;
All the Mosfets are hooked into PWM pins for versatility;
Servo style connectors are used to connect to the endstops, motors, and LEDs. These connectors are gold plated, rated for 3A, very compact;
SD Card add on available
LEDs indicate when heater outputs on
Option to connect 2 motors to Z for Prusa Mendel

4. A4988 stepper driver
This product 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.
