X-NUCLEO-IHM15A1 Data brief Dual brush DC motor driver expansion board based on STSPIN840 for STM32 Nucleo Features * * Voltage range from 7 to 45 V Output current up to 1.5 Arms for each motor * * Two independent current limiters with adjustable OFF time Full protection set including: overcurrent, short-circuit, under voltage lock out and thermal shutdown Parallel operation Compatible with Arduino UNO R3 connector Compatible with STM32 Nucleo boards * * * Description The X-NUCLEO-IHM15A1 dual brush DC motor driver expansion board is based on the STSPIN840 for STM32 Nucleo. It provides an affordable and easy-to-use solution for the implementation of compact motor driving applications such as thermal printers, robotics and toys. Thanks to the parallel operation, it can be easily converted to a single brush DC driver with double current capability. The current limiters and complete set of protection features make it suitable for rugged applications. The X-NUCLEO-IHM15A1 is compatible with the Arduino UNO R3 connector and most STM32 Nucleo boards.
