StepStick Stepper motor driver A4988 With Easy to use Shield for Stepper Motors
Description
- Short-to-ground and shorted-load protection
- Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
- Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
- Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates
- Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
The A4988 stepper motor driver carrier is a breakout board for Allegro's A4988 microstepping bipolar stepper motor driver. The driver features adjustable current limiting, overcurrent and overtemperature protection, and five different microstep 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). As well as the A4988, this listing also includes a very handy shield for the stepper driver. The shield includes female headers for power, male headers for stepper motor control, a DIP switch for step resolution, 4 pin housing for connection to the stepper motor, and an on-board capacitor. Please see below for a description of the breakout board.Resources: • A4988 Datasheet -> http://www.pololu.com/file/download/a4988_DMOS_microstepping_driver_with_translator.pdf?file_id=0J450 • StepStick Product Page -> http://www.pololu.com/product/1182 • Schematic -> http://makertreeebayimages.azurewebsites.net/ebayimages/ebaycontent/0J3359.600.png • StepStick Wiki -> http://reprap.org/wiki/StepStickWhat you get: • 1 x StepStick module with Headers pre-soldered • 1 x aluminium Heatsink
