Description:
Mega 2560 control board is an ATmega2560 as core micro-controller development board itself has 54 digital I/O input/output terminals (14 can be used as PWM outputs), 16 simulation than the input side, group 4 UARTs (hardware serial ports), 16 MHz crystal oscillator, USB connection, ICSP pin and reset button. Based on open-source principles, it allows you to free download for use in project work, school teaching, motor control, interactive works.

Connect Mega 2560 board to computer with USB cable, or power it with a power adapter or battery, then the board could work.
RAMPS 1.4 board is 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.
This full graphic smart LCD 12864 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.
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 all actions like calibration, axes movements can be done by just using the rotary encoder on the smart controller. Print your 3D designs without PC, just with a g-code design stored on the SD card.
