Since January 21, 2015, we are distributing the A4988 controller produced by Pololu USA.
This breakout card supports an Allegro A4988 Microstepping driver (DMOS) including over-current protection. It is the step-by-step motor controller that can be found on the control cards of 3D printers (for example: OrdBot Hadron), plotter, etc.
This controller allows you to control bipolar micro-stepping motors with a maximum of 2 Amps per coil (pay attention to heat dissipation conditions!!!).
Here are some key features of this breakout:
Remember to take note of the technical data sheet of the A4988. Indeed, if he is capable of driving a large current, it cannot do it in any condition, you must be attentive to the heat dissipation.
