6. Rotate the potentiometer on X-NUCLEO-IHM16M1 to regulate the motor speed.
1. To supply the NUCLEO-G431RB from the USB, the jumper JP5 must be connected between Pin 1 and Pin 2. For further
details on Nucleo settings refer to [3].
2. Supply voltage must be off before changing the control mode.

Table 3 shows the jumper configuration on the X-NUCLEO-IHM16M1 board as shown in
the jumper selection, it is possible to choose the 1-shunt or 3-shunt current-sensing mode, the Hall encoder with
pull-up, or the external supply for the NUCLEO-G431RB board.

JP4 and JP7
1. JP4 and JP7 must have both the same configuration: both left open for 3-shunt configuration, both closed for 1- shunt
configuration. On the silkscreen, the correct position for 3- or 1-shunt is indicated together with the default position.
Table 4 shows the main connectors on the X-NUCLEO-IHM16M1 board.

The X-NUCLEO-IHM16M1 is stacked on ST morpho connectors, male pin headers (CN7 and CN10) accessible
on both sides of the board. They can be used to connect this power board to the NUCLEO-G431RB board. All
signals and power pins for the MCU are available on the ST morpho connectors. For further details refer to the
"ST morpho connectors" section in [3].
