    Description

    For sale is an almost full reel of Allegro A4988 stepper motor drivers.
    These chips operate from 8VDC to 35VDC and up to 2A driving current.
    They are chopper drivers so the voltage you run them at doesn't have to
    match your motor.
    This was a full reel purchased for a prototype run of a new product.  We used approximately 40 pieces and assumed the board house stuffing the boards would use the rest for the full build of the boards.  When the product run was finished they sent us the almost full reel because they had bought new reels for the full run.   Anyway - here they are.  You can see from the pictures that the reel is wound out almost to the edge of the spool.  I can't say for sure how many were removed and I'm not going to count them, but definitely less than 100 and really it should be about 40..
