RioRand 5 x A4988 motor driver with heatsink,3D printer RepRap Prusa, Mendel

1.A4988 driver
This product is a carrier board or breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection by Pololu; we therefore recommend careful reading of the A4988 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil.

This 11x11x5mm heatsink, purchased for use with the pololu A4988 drivers, despite their tiny size they are still very large when placed on the driver, may require machining to fit on the Pololu drivers but if careful with soldering and it clears the SMD resistors I don’t see the need for any modification.

Print from SD card or via USB connection

Very easy to use. It will simply work, build volume comparable with the latest machines of the US, with a similar nozzle size for fine resolution printing, comes with an attractive enclosed build space, no covers or hoods need to purchase as an extra item again! Simple user interface and communicates via either SD Card or USB. Simplified windows produces reliable G-Code, and leaves plenty of room for sophisticated users to upgrade to other software platforms.

It takes 1.75 mm filament ABS plastic. The nozzle and bed temperatures can be easily controlled, and a simple load and unload filament system allows for a quick change and the use of a variety of filament types. ABS is the recommended filament, and with the heated build platform and enclosed temperature controlled build space this is much more effective than other printers without good temperature control. Unlike many 3D printers the nozzle moves around the print, so the build platform is not being shaken around adding to the adhesion problem of materials like ABS.
