The Nucleo-G431RB is a member of the Nucleo-64 board family. The Nucleo-64
|
|
|
|
|
is a standard board for use with several STM32 parts in the LQFP64 package.

These examples are dedicated for the X-NUCLEO-IHM16M1 expansion board
|
|
|
|
|
based on STSPIN830 driver for three-phase brushless DC motors.
|
|
|
|
|
|
|
|
|
|
X-NUCLEO-IHM16M1 must be configured to work with FOC and 3-shunt
|
|
|
|
|
resistors. See ST documentation for details.
