LCD 12864 is an rotary encoder and a 128 x 64 dot matrix LCD display, full graphic Smart Controller contains a SD-Card reader.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
RAMPS interfaces an Arduino-compatible Mega with the powerful Arduino-compatible MEGA platform
The Mega 2560 is compatible with most shields designed for the Arduino Duemilanove or DiecimilaA4988 is a complete microstepping motor driver with built-in translator for easy operation
DRV8825 is upgrade of A4988, 4-layer PCB for improved heat dissipation and decrease chip resistance

Description

RAMPS 1.4Controller Board:
