UM1771

Main features

The characteristics of the EVAL6474H-DISC are the following:



DC voltage range from 8 V to 45 V



Maximum load phase current at 3 Ar.m.s.



Footprint for external resonator or crystal



Control interface through trimmer - user keys and switch motor input



Control through LED indicators



Interface control by USB and debug outputs



Compatible with SPINFamily evaluation tool



Autonomous board due to an embedded firmware



Up to 1/16 microstepping



Optimized layout on 2 layers board - low cost and high thermal performance

The possibility with these boards is double:



Adapt the settings with your specific setup (motor - voltage) by using the dedicated PC

application.

–

The user is able to save inside the board the specific parameters depending on

user setup



Using the board (with user parameters) directly on site - without a connected PC.
