Note: RAMPS is deprecated technology
We provide new electronics, like Megatronics. Which is cheaper, has more features and is compatible with RAMPS. It is advised to use Megatronics instead of RAMPS for new printers. Check our electronics comparison page here for more details.

RepRap Arduino Mega Pololu Shield, or RAMPS for short. It is designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an Arduino MEGA with the powerful Arduino MEGA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on an Arduino MEGA shield for easy service, part replacement, upgrade-ability and expansion. Additionally as long as the main RAMPS board is kept to the top of the stack a number of Arduino expansion boards can be added to the system.

In RAMPS 1.4, the resistors and capacitors are now surface mount to fit more passive components. This does add another set of steps to assembly, but we stuck with larger sizes to make it fairly painless.

This is the full kit. It includes:
- An Arduino mega 2560
- Fully assembled RAMPS 1.4 board
- 4x Stepstick stepper drivers, including heatsinks

Components on the ramps board are tested for 24V input max
