STEPPER MOTOR DRIVER A4988:
The A4988 stepper motor driver carrier is a breakout board for Allegro’s A4988 micro stepping bipolar stepper motor driver. The driver features adjustable current limiting, overcurrent and overtemperature protection, and five different micro step resolutions (down to 1/16-step). It operates from 8 – 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling).
RAMPS 1.4 3D PRINTER CONTROL BOARD:
The RAMPS (RepRap Arduino Mega Shield) is an all-in-one design to fit the necessary components for a 3D printer into one plug in shield for an Arduino MEGA. The plugin shield design includes plug in stepper drivers and extruder control electronics sockets for easy service, part replacement, upgrade-ability, and expansion. Additionally, a number of Adruino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack. Ramps boards are the heart of most DIY 3D printers on the market and a nice clean compact way to integrate all the systems into a compact enclosure mountable format.
