X-NUCLEO-IHM12A1 Low voltage dual brush DC motor driver expansion board based on STSPIN240 for STM32 Nucleo Data brief Description The X-NUCLEO-IHM12A1 is a low voltage dual brush DC motor driver expansion board based on the STSPIN240 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. Thanks to its programmable current limiter and complete set of protection features, it offers high levels of performance and robustness. The X-NUCLEO-IHM12A1 is compatible with the Arduino UNO R3 connector and most STM32 Nucleo boards. Features Low voltage range from 1.8 V to 10 V Current up to 1.3 A r.m.s Current control with adjustable off-time Full protection overcurrent and short-circuit protection Low RDS(ON) power stage (HS + LS = 0.4 typ.) Thermal shutdown Compatible with Arduino UNO R3 connector Compatible with STM32 Nucleo boards Connection for two independent DC motors RoHS compliant September 2016 DocID029744 Rev 1 For further information contact your local STMicroelectronics sales office 1/4 www.st.com Schematic diagram 1 X-NUCLEO-IHM12A1 Schematic diagram Figure 1: X-NUCLEO-IHM12A1 circuit schematic 2/4 DocID029744 Rev 1 X-NUCLEO-IHM12A1 2 Revision history Revision history Table 1: Document revision history Date Version 27-Sep-2016 1 Changes Initial release.
