RAMPS 1.4 Shield

The RAMPS 1.4 Shield (RepRap Arduino Mega Pololu Shield) is a powerful and modular controller board that’s widely used in 3D printers, CNC machines, and robotic platforms. Built to sit on top of an Arduino Mega 2560, it provides an efficient way to manage motion control, heating elements, fans, and display interfaces—all in one compact unit.

Thanks to its open-source design, the RAMPS 1.4 is fully customizable. It supports Pololu-compatible stepper driver modules (like A4988 and DRV8825), which are easy to insert and replace without soldering. This modularity makes it highly versatile and beginner-friendly.

The shield also features terminals for 3D printer heaters, thermistors, end-stops, and cooling fans. It offers support for an LCD display with SD card slot, which allows standalone printing without a PC. Additionally, it’s compatible with Marlin and other open-source firmware.

Whether you’re building a DIY 3D printer or automating machinery, the RAMPS 1.4 Shield gives you reliable, flexible control.

For the best results, pair this with an Arduino Mega board and components from our Electronics Components section.
