Component kit for 3D printer – Beginner

The RAMPS 1.4 3D PRINTER CONTROLLER+Mega2560 with Cable compatible with Arduino +5Pcs 4988 Driver With Heat Sink+LCD 128×64 Display Kit is the new  3D Printer Kit, developed especially for those who are interested in a 3D printer.

RAMPS 1.4 Board : 

The RAMPS 1.4 is Mega Pololu Shield, or RAMPS, design to fit the entire electronics needed for a RepRap in one small package for a low cost. RAMPS interfaces a Mega with a powerful MEGA platform and has plenty of room for expansion. The modular design includes plug-in stepper drivers and extruder control electronics on the MEGA shield for easy service, part replacement, upgrade-ability, and expansion. Additionally, a number of Arduino expansion boards can be added to the system. As long as the main RAMPS board is kept to the top of the stack.

Mega2560 Arduino:

Mega2560 is an ATmega2560 as the core microcontroller development board itself has 54 groups digital I/O terminal (14 Pin PWM outputs). 16 sets of simulation than the input side, group 4 UARTs (hardware serial ports), using the 16 MHz crystal oscillator. With the boot-loader, download the program directly via USB without having to go through other external writers. Supply part of the optional USB power, or as an external power using the AC-to-DC adapter and battery.

Specifications and Features :

1. USB type B receptacle.
2. SD Card adds on available.
3. Fits 5 Pololu stepper driver board.
4. LEDs indicate when the heater outputs on.
5. Expandable to control other accessories.
6. Heated bed control with an additional 11A fuse.
7. Option to connect 2 motors to Z for Prusa Mendel.
8. I2C and SPI pins left available for future expansion.
9. It has provisions for the cartesian robot and extruder.
10. All the Mosfets are hook into PWM pins for versatility.
11. 3 MOSFETs for heater/fan outputs and 3 thermistor circuits.
12. Fused at 5A for additional safety and component protection.
13. These boards are on pin header sockets so they can be replaced easily or remove for use in future designs.
14. Servo-style connectors are used to connect to the end stops, motors, and led. These connectors are gold plated, rated for 3A, very compact, and globally available.
