17.5 MOTION MEMS AND ENVIRONMENTAL SENSOR EXPANSION BOARD (X-NUCLEO-IKS01A2) 407

FIG. 17.2 X-NUCLEO-IHM02A1 expansion board.

17.4 LOW-VOLTAGE THREE-PHASE BRUSHLESS DC MOTOR BOARD
(X-NUCLEO-IHM11M1)

This is a low-voltage three-phase brushless DC motor driver expansion board (Fig. 17.3)
based on the STSPIN230. The board is compatible with the Arduino UNO R3 connector.
The board is designed for six-step and FOC algorithms. The basic features of this expansion
board are as follows:
• 1.8–10V operation
• up to 1.3A rms current
• overcurrent and short-circuit protection
• thermal shutdown
• current control with adjustable off time
• hall/encoder sensor connector and circuit
• potentiometer for speed regulation

17.5 MOTION MEMS AND ENVIRONMENTAL SENSOR EXPANSION
BOARD (X-NUCLEO-IKS01A2)

This is a motion MEMS and environmental sensor expansion board (Fig. 17.4), equipped
with three-dimensional (3D) accelerometer, 3D gyroscope, 3D magnetometer, humidity and
temperature sensor, and ambient atmospheric pressure sensor. The board is interfaced via the
