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.
Since this assembled RAMPS 1.4 board has the connectors for the SDRAMPS MicroSD card reader installed it is not compatible with the LCD Smart Adapter board without modification.
This RAMPS 1.4 board is fully assembled. DOES NOT Include wire or motor and thermistor connectors.
