The great Reprap Arduino Mega Pololu Shield 1.4 RepRap electronics board. The RAMPS 1.4 board, when paired with an Arduino Mega 2560 or 1280 microcontoller board and four Pololu stepper drivers, can fully control all of the needed functions of a Reprap printer.
The RAMPS 1.4 board is an upgrade to v1.3 as it now uses surface mount LEDs, resistors, and capacitors.
Does not include the required Arduino (1280 or 2560) or Pololu stepper drivers. Four pololu stepper drivers are required with an optional fifth driver for a second extruder.
This RAMPS 1.4 board is fully assembled. DOES NOT Include wire or motor and thermistor connectors.
