SAVING SPACE: The RAMPS 1.4 board is designed to fit the entire electronics needed for a RepRap in one small package. So it can save space and cost.
SCALABLE: RAMPS interfaces an Mega with the powerful MEGA platform and has plenty room for expansion. A number of expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack.
EASY TO USE: Using the bootloader, you can download the program directly via USB without using other external writers. Development IDE interface is based on open-source principles, allows you to free download for use in project work, school teaching, motor control, interactive works.
MODULAR DESIGN: The modular design includes plug in stepper drivers and extruder control electronics on an MEGA shield for easy service, part replacement, upgrade-ability and expansion.
POWER SUPPLY AND DRIVER: Supply part of the optional USB power, or as an external power using the AC-to-DC adapter and battery. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil.
