17.9 THREE-PHASE BRUSHLESS DC MOTOR BOARD (X-NUCLEO-IHM07M1) 415

FIG. 17.9 X-NUCLEO-IKA01A1 expansion board.

17.8 BLUETOOTH LOW-ENERGY EXPANSION BOARD
(X-NUCLEO-IDB04A1)

This is a Bluetooth low-energy expansion board (Fig. 17.10) which interfaces with the
Nucleo development boards via SPI bus. The board enables Bluetooth communication with
other Bluetooth compatible devices. The basic features of this board are as follows:
• Bluetooth low-energy 4.0 master and slave compliant
• equipped with Arduino Uno R3 connector
• low-power consumption (7.3mA RX and 8.2mA TX)
• +8dBm maximum transmission power
• 88dBm receiver sensitivity

17.9 THREE-PHASE BRUSHLESS DC MOTOR BOARD
(X-NUCLEO-IHM07M1)

This is a three-phase brushless DC motor expansion board (Fig. 17.11) based on the DMOS
fully integrated driver L6230. The board enables three-phase brushless DC motor to be con-
trolled from the Nucleo development boards. Overcurrent and thermal protection are pro-
vided and the driver is optimized for six-step and FOC algorithms. The basic features of
this expansion board are as follows:
•8–48V operating voltage
• three-phase BLDC/PMSM motor driver
• 100kHz operating frequency
