Description
The X-NUCLEO-IHM17M1 is a low voltage three-phase brushless DC motor driver
expansion board based on the STSPIN233 for STM32 Nucleo.
It provides an affordable and easy-to-use solution for the implementation of portable
motor driving applications such as thermal printers, robotics and toys.
The X-NUCLEO-IHM17M1 is compatible with the Arduino UNO R3 connector and
most STM32 Nucleo boards.
The board is designed for six-step and FOC algorithms with single and three-shunt
sensing topology.
