RAMPS 1.4 3D Printer Board

The shield is designed to control a CNC or a 3D printer. It is equipped with sockets for 5 steppers A4988. It feeds separately with the voltage required for engine operation.

In addition to the Arduino connection pins, there are connection pins for motors and other peripherals, such as: thermistors, LCD screen, SD card adapter, and communication ports.

The shield is provided with an extra filtering capacitor for each driver.

This is an expansion board design for the user’s need for a RepRap in one small package for low cost.  This is an all-in-one design plug in shield which fits the necessary components for a 3D printer compatible with Arduino Mega

RAMPS has an Arduino Mega interface and it is compatible with the Arduino Mega platform that features plenty of room for expansion.

Technical characteristics A4988:

• Motor voltage: 8V - 35V;
• Logic circuit voltage: 3V - 5.5V;
• Current: 2A (MAX);
• 5 modes for steps: full, 1/2, 1/4, 1/8 and 1/16;
• Protection against: overvoltage, overcurrent and overtemperature.
