STMicroelectronics X-NUCLEO-IHM12A1 Dual Brush DC Motor Driver Expansion Board | STSPIN240 Shield | For STM32 Nucleo Robotics
Description
SPIDER Automation STMicroelectronics X-NUCLEO-IHM12A1 Dual Brush DC Motor Driver Expansion Board provides developers with a versatile, low-voltage motor-driving platform designed specifically for portable embedded applications. Powered by the STSPIN240 low-voltage dual brush DC motor driver, the board is engineered to operate across a broad supply window from 1.8V to 10V, making it an exceptional choice for lithium-ion or multi-cell alkaline battery-operated devices.
The X-NUCLEO-IHM12A1 features an ultra-low power-stage resistance (HS + LS = 0.4 Ohm typical) that minimizes thermal dissipation and maximizes battery efficiency. With integrated PWM current control featuring adjustable off-time, full diagnostic protections, and native stackability with STM32 Nucleo boards via Arduino UNO R3 connectors, this expansion shield accelerates the development of smart toys, thermal receipt printers, and compact mobile robots.
