The RAMPS1.5 is an upgraded version of the widely used RepRap Arduino Mega Pololu Shield (RAMPS) controller board, designed specifically for 3D printers and three-axis CNC machines. This shield plugs directly into an Arduino Mega 2560 and provides the complete interface between the microcontroller and the motors, heaters, thermistors, and end stops of a RepRap-style machine. The board supports up to five stepper motor drivers, enabling simultaneous control of the X, Y, and Z axes plus two extruders, or a spindle motor for CNC applications. It is compatible with a broad range of plug-in stepper driver modules, including the A4988, DRV8825, LV8729, and TMC2100, allowing users to select the driver that best matches their motor current and microstepping requirements.

Compared with the earlier RAMPS 1.4, the RAMPS 1.5 moves to surface-mount MOSFETs and surface-mount fuses. The MOSFETs are soldered flush to the board with heat sinks on the underside, and the fuses are small SMD devices rather than the large yellow fuse holders used on the 1.4. This change improves thermal performance and frees space for cooling, making it easier to fit heat sinks and fans while reducing the risk of overheating during long prints. The board also provides dedicated heater and fan MOSFET outputs, multiple thermistor inputs, and support for character and graphical LCD displays for monitoring print status.

The RepRap RAMPS 1.5 controller operates from a 12V to 24V DC input and is rated for a maximum input power of 200W. It exposes I2C and SPI pins for expansion and uses servo-style connectors for the stepper outputs, simplifying wiring. Because the RAMPS 1.5 is a shield rather than a stand-alone board, an Arduino Mega 2560 is required for operation. This combination makes the RAMPS 1.5 a flexible, serviceable, and widely supported platform for DIY 3D printers, CNC routers, and other motion-control projects.
