Keyestudio Mega 2560 board
Keyestudio Mega (core to ATmega2560) is a development board (used with16MHz crystal oscillator ) of microcontroller. There are 54 I/O (input/output ) digital interfaces (of which 14 are PWM outputs), 16 analog inputs and 4 UART (hardwareserial ports). With its bootloader, program can be downloaded directly with USB and you don’t need to use other external programmer. It can be driven directly by USB, or AC-to-DC adapter and battery.
LCD 12864 Smart Controller
It contains a SD-Card reader. You can easily 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.
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 Aduino Mega with the powerful Aduino MEGA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on an Aduino MEGA shield for easy service, part replacement, upgrade-ability and expansion. Additionally, a number of Aduino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack.
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.
