The brand new RAMPS 1.4 SB is a shield designed for expand Arduino Mega board. Using it, you can connect drivers (Pololus), engines, power supply, thermistors, fans, double extruders... to a single board.

The highest temperature for Toshiba MOSFET`s are 45ºC (113 ºF) with the heatbed turned on. It can hold 120V and 178A peak of current. With these characteristics is not necessary to ventilate the RAMPS.

RAMPS 1.4 SB uses Schottky protection diodes welded to the shield, preventing melt.

Each board is made and tested in Galicia (Spain).
