BOARD SETUP
A step-by-step connecting procedure is available in Section 1.4.3 “Connecting the
F1 LV Evaluation Platform to the Add-on Board”. Please make sure that POT R4
on the Evaluation Platform is turned fully CCW.
To connect either the NMB motor (with Jumper J5) or a brushed DC motor of your
choice (through terminals V and U of add-on connector J4), keep in mind to attach each
motor phase firmly to the connector. Bad contacts can damage the add-on and will
wear out the motor in time. There is no rule for attaching a specific motor lead to a
phase line on the add-on. Keep in mind the correspondences on the software side
when testing or measuring directly on that motor phase.

HARDWARE

General Architecture
The BDC add-on uses a typical H-bridge control configuration suitable for two-phase
BDC motors, using four MOSFETS commanded through four bipolar transistors. The
demo software varies the motor speed by pulse-width modulating the H-bridge drive.

WARNING
Before connecting the motor, make sure the power rating of the motor is equal to or
less than the power rating of the board, as shown in Appendix B. “Conversion Fac-
tors”. Also, make sure the configuration parameters inside the software or the GUI are
correct for the motor you are using. Failure to comply with this warning could lead to
malfunction of the board and the motor, and could result in physical harm.
Before beginning the start-up procedure, complete a visual check of the board and the
motor for connectivity and mechanical damage. If damage is found, DO NOT power-up
the board. Otherwise, you may further damage the equipment. Contact Microchip’s
local office or distributor immediately.
