Description

The EVLPOWERSTEP01 demonstration board is

a microstepping motor driver delivering up to

10 A

r.m.s.

. In combination with the STEVAL-

PCC009V2 communication board and the

evaluation software, the board allows the user to

investigate all the features of the powerSTEP01.

In particular, the board can be used to check the

performance and to regulate the parameters in

order to fit the application requirements.

The EVLPOWERSTEP01 supports the daisy

chain configuration making it suitable for the

evaluation of the powerSTEP01 in multi motor

applications.
