A distributor has recently informed customers that the Little Step-U (Parallax #27938) had been made obsolete.
While it appears that they will no longer be selling it,
we have a number of OEM customers using it and it will continue to be available directly from TLA Microsystems.
There is no intention or expectation of discontinuing manufacture of the Little Step-U.
However, because there has been a rush of direct orders following the notice, stock levels have suffered. We are working to
remedy that and to provide an online purchase facility.
We apologise for any inconvenience.
|The Little Step-U is a
complete stepper motor control solution in the form of a 1" x 2" PCB. A single
TTL serial connection is sufficient to control a 30V/3A unipolar motor up 5000
steps/second in a set and forget fashion. Commands instruct the motor to move to an
absolute position, a relative position, until an input is activated or return to one of
two previously marked positions. An inbuilt linear ramp function allows the motor to be
accelerated and decelerated over a defined period. Other options are to drive the motor in
full, half and wave drive modes, stop with windings on or off or to act as a simple
translator/drive with step and direction inputs.
