4.2 System Configuration and Documentation

The application is designed to drive the 3-phase BLDC motor. The HW
is a modular system composed from board and motor. There are three
possible hardware options:

High-Voltage Hardware Set Configuration

Low-Voltage Evaluation Motor Hardware Set Configuration

Low-Voltage Hardware Set Configuration

The following subsection shows the system configurations.

They systems consists of the following modules (see also
