This product is a carrier board or breakout board for Allegro's A4988 DMOS. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A. Stepper Motor Driver 1A - Original from Pololu The A4988 stepper motor driver carrier is a breakout board for Allegro's A4988 microstepping bipolar stepper.

* Drivers with status monitoring can report printer and print job status to the Windows Spooler and other Windows applications, including BarTender. ** Downloaded fonts typically print faster, because they can be rendered directly by the printer. Otherwise they have to first be rasterized by Windows and output to the printer as bitmaps.

*** If you plan to encode EPC Gen2 smart cards using the ZXP Series 7 printer driver, you will also need to install the encoder tool available. True Windows printer Drivers by Seagull can be used with any true Windows program, including our for,,, RFID encoding, and card printing.

FLEX: The golf shaft's resistance to bending when subjected to a longitudinal force. In other words, how much will it bend if you grab the ends and do a Rambo on it. (Actually, it is more often done by clamping one end and hanging a weight on the other end, per the drawing below.) The five FLEX classifications in common use are: L - Ladies; A - Average or Senior; R - Regular; S - Stiff; and X - eXtra stiff. Also in limited use are XL for eXtra fLexible, RR for softeR Regular, FIRM for Not-Quite-Stiff, and XX for eXtra eXtra stiff.

However, each company sets their own standards and definitions for these terms, so one company's R may be another's S or A. Golfsmith tests each shaft they sell and rate it on their own 'RSSR' (Recommended Swing Speed Range) scale, so the various shafts they carry can be compared and rated on a more consistent scale. Dynacraft uses a similar system they call 'DSFI'--- the 'Dynacraft Shaft Flex Index', which is also very useful in comparing shafts from different companies.

True Temper has for many years had four levels (100-400) for each flex in their 'Gold' shaft series with 300 being the standard: I.E. R300 is the normal R-flex with R100 being more flexible and R400 a bit stiffer but with both still within what they feel is the Regular range. They use WEIGHT-SORTING to make sure their Dynamic Gold shafts are matched within a flex. Royal Precision (formerly Brunswick) developed the FREQUENCY MATCHING system for determining flex. For their RIFLE series of steel shafts they use a number from 4.5 to 7.0 (based on cycles-per-minute oscillations of the raw shaft) to designate the shaft flex, with 4.5 being the most flexible and most closely matching the A-flex rating used by most manufacturers.

A 5.5 shaft is a Regular flex and the 6.5 is a Stiff. As there are no absolute industry standards for these classifications, the same stiffness designation may not mean the exactly the same thing between brands.
