Arduino Mega 2560 Board:
The MEGA 2560 is designed for more complex projects. With 54 digital
I/O pins, 16 analog inputs and a larger space for your sketch it is the
recommended board for 3D printers and robotics projects. This gives
your projects plenty of room and opportunities.
The Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB
Technical specs :
Microcontroller ATmega2560
Operating Voltage 5V
Input Voltage (recommended) 7-12V Input Voltage (limit) 6-20V
Digital I/O Pins 54 (of which 15 provide PWM output)
Analog Input Pins 16
DC Current per I/O Pin 20 mA DC Current for 3.3V Pin 50 mA
Flash Memory 256 KB of which 8 KB used by bootloader
SRAM 8 KB
Ramps 1.4
:Ramps is short for reprap Arduino mega pololu shield, it is mainly designed for the purpose of using pololu stepper driven board (similar to 4988 driven board). Ramps can only work when connected to its mother board Mega 2560 and 4988/DRV8825. Owning to its stability in operation and great compatibility with most 3Dprinter (all reprap-model such as pursa i2 and i3). The combination of Ramps1.4+MEGA2560+A4988/DRV8825 is becoming a mainstream of DIY 3D printer control board.
Features
3 MOSFET 3 MOSFET are applied to the heater/ fan and thermistor circuit. 4. Adding another 5A to protect the component parts.
5. An 11A fuse is added to the hotbed 6. Support 5 stepper drive board
7. The adoption of Pin Header as pololu makes it more convenient to repair or change. 8. I2C and SPI are reserved for expanding
9. All the MOSFET can be controlled by PWM
10. Use the interface of servo motor to adjust the level of printing platform automatically. 11. Adding a SD module for SD ramps module.
12. LED can indicate the status of the heater (the open and close of MOS). 13. 2 stepper motor for Z axis in parallel.
A4988 Stepper Motor Driver :
without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient
additional cooling). This board ships with 0.1″ male header pins included but
not soldered in.
Arduino USB cable :
This is a standard USB cable with USB 2.0. This is the most common A to B Male/Male type peripheral cable, the kind that's usually used for printers. Compatible with most USB boards as well as USB Arduino boards like the Uno.
