3D Printer Controller Kit RAMPS 1.4+2560 Board+A4988 Stepper Motor Driver

Description:

2560 Control Board - The board is a microcontroller board based on the 16AU .It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
RAMPS 1.4 - The modular design includes plug in stepper drivers and extruder control electronics on an for easy service, part replacement, upgrade-ability and expansion.
LCD 12864 with Controller - This full graphic Smart Controller contains a SD-Card reader, an rotary encoder and a 128 x 64 dot matrix LCD display. You can easy connect it to your Ramps board using the "smart adapter" included.
A4988 driver module.
