The kit contains the Mega board, the Ramps 1.4 shield and 4 A4988 controllers with heatsinks.
It has an Atmega2560 chip running at 16Mhz with a factory loaded bootloader with 54 digital input / output pins (from which 14 can be used as PWM outputs) and 16 analog inputs, 4 UART (hardware serial ports). The board includes a USB connector, an ICSP port, a reset button and some status LEDs. Atmega16U2 programmed as a USB-to-serial converter. Simply connect it to a computer with a USB cable or power with a power adapter and DC connector.
RepRap Arduino Mega Pololu Shield (RAMPS) version 1.4 for 3D printer. RAMPS is a shield for the Arduino Mega - The outputs of the Arduino board are redirected to the motor drivers. To have the complete electronics for a 3D printer you need a RAMPS, an Arduino Mega and at least four stepper motor drivers
