The Boardoza VNH5019 is a high-current H-Bridge DC motor driver module based on the STMicroelectronics VNH5019A-E full-bridge motor driver IC. Designed for demanding automotive and industrial applications, this board integrates dual high-side and two low-side MOSFET switches using ST’s proprietary VIPower® M0 technology, delivering high efficiency, robust protection, and reliable motor control.
With support for PWM control up to 20 kHz and integrated current sensing, this module is ideal for robotics, automation systems, battery-powered vehicles, smart mobility projects, and industrial motor control applications where high current and protection features are essential.
