3D Printer Controller Kit for Arduino Raspberry Pi contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.This full graphic Smart Controller contains a SD-Card reader, an rotary encoder and a 128 x 64 dot matrix LCD display. Please note: With a SD Card base on back, SD card not included. Print your 3D designs without PC, just with a g-code design stored on the SD card. LCD 12864 graphic smart display module with blue backlight, small and light appearance, suitbale for copiers, fax machines, laser printers, industrial test equipment, networking.

• Mega 2560 control board: The board is a microcontroller board based on the ATmega2560-16AU .It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.
• Mega Pololu Shield (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.
• LCD 12864 with Controller: This full graphic Smart Controller contains a SD-Card reader, an rotary encoder and a 128 x 64 dot matrix LCD display. You can easy connect it to your Ramps board using the smart adapter included.
• A4988 driver module: A4988 Stepper Motor Driver Board is a breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection; please read the A4988 datasheet carefullybefore using this product.
• Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver. (More generally, rewiring anything while it is powered is asking for trouble.
