TRINAMIC TMC249A-SA Stepper Motor Driver, 3V to 5.5V supply, 34V/50 mA/8 Outputs, SOIC-28The TMC249A SA is a smart high current Micro Stepping Driver for bi polar stepper motors. The integrated unique sensorless stall detection stallGuard makes it a good choice for applications, where a reference point is needed, but where a switch cannot be used. The ability to predict an overload makes this an optimum choice for drives, where a high reliability is desired. It provides an SPI interface as well as the classical analogue digital control. A

The TMC249A-SA is a smart high current Micro Stepping Driver for bi-polar stepper motors. The integrated unique sensorless stall detection stallGuard� makes it a good choice for applications, where a reference point is needed, but where a switch cannot be used. The ability to predict an overload makes this an optimum choice for drives, where a high reliability is desired. It provides an SPI� interface as well as the classical analogue/digital control. A full set of protection and diagnostic features makes this device very rugged. It directly drives external MOSFETs for currents up to 6A. This way it reaches an extremely high efficiency and allows driving of a high motor current without cooling measures even at high environment temperatures. The high motor current makes this device ideal for miniaturized highly dynamic and high torque drive systems.

Lame art and bad prose. This amateur effort deceived my by one good review. Writing this review to tell you not to waste your money.

Better then the competitors
Size: Medium Size
I bought these in both small and medium size. The small bag fits the Kitsch solid hair soap perfectly. They also fit a bar of Dove soap. Some types of soap, like Zest, are a tighter fit bit still work. If you want more of a washcloth style with extra suds, use the medium bag. The medium bag works well with those large bars of soap, like Duke Cannon Big Brick of soap. I hand these off little hooks in my shower so the bag dry faster and so I appreciate the loop they have on the corner. The folding top works way better then a drawstring. I also love the exfoliating texture. Overall, these are well worth the price.
