RAMPS 1.4 3D Printer Controller Board Shield - Mega 2560 RepRap Marlin

The RAMPS (RepRap Arduino Mega Pololu Shield) 1.4 is the most widely used controller shield for DIY and RepRap-style 3D printers. It plugs directly onto an Arduino Mega 2560 (sold separately) and breaks out everything needed to drive a 3-axis printer with a hotend and heated bed: five stepper-driver sockets, three MOSFET outputs, three thermistor inputs, end-stop headers, and servo / aux pins.

• 5 sockets for pluggable stepper driver modules (A4988, DRV8825, TMC2208/2209, etc. — sold separately)
• 3 MOSFET outputs — heated bed (D8, 11A fuse), hotend (D9/D10, 5A fuse), and fan
• 3 thermistor inputs for hotend, heated bed, and chamber
• 6 end-stop headers (X/Y/Z, min and max)
• SPI & I²C broken out for LCD smart controllers and expansion
• Servo / aux pins for BLTouch-style auto-bed-leveling probes
• Polyfuse-protected 5V and 12V rails — recoverable from short circuits

• Designed for the Arduino Mega 2560 (sold separately)
• Compatible firmware: Marlin, Repetier, Sprinter, Smoothieware (with adapter)
• Drop-in upgrade path for RepRap-style printers (Prusa i3 / Mendel, Anet A6/A8, MakerFarm, Folger Tech, etc.)
• Works with 12864 Graphic LCD Smart Controllers via the EXP1 / EXP2 headers

• 1× RAMPS 1.4 controller shield

Stepper drivers, Arduino Mega 2560, LCD controller, and cables are not included.

• RAMPS 1.4 + 12864 LCD combo (no drivers) — RAMPS + LCD bundle
• Build-your-own RAMPS + ATmega 2560 kit (pick LCD + driver type) — RAMPS 1.4 + Mega 2560 R3 configurable kit
• Stepper drivers sold separately in 4-packs in our store — A4988, DRV8825, and TMC2209 with heatsinks
