STMicroelectronics EVAL-VHN5019-P2 电机驱动器扩展板
STMicroelectronics EVAL-VHN5019-P2 电机驱动器扩展板通过 Arduino 兼容的 SPC56P-Discovery 和 STM32 Nucleo 板,使控制两个双向、大功率、有刷直流电机变得容易。该板带有一对强大的 VNH5019A 电机驱动器(工作于 5.5 到 24V 的电压范围,可提供每通道 12A(30A 峰值)连续电流),并内置了典型应用的大部分元件,如上拉和保护电阻器和 FET,用于电池反接保护。这款多功能电机驱动器面向广泛的用户群,从只想要一个能用于 Arduino 和 Nucleo 的即插即用电机控制解决方案的入门用户,到想要能够直接连接 ST 强大的电机驱动器 IC 的专业人员。对于没有 Arduino 的普通用途,如果默认值不方便,而且 VNH5019A 控制线路在电路板左侧越线,则 Arduino 引脚映射全都可以自定义。这种多功能性,加上能够选择从扩展板直接驱动 Arduino,将该板与类似竞品电机驱动扩展板区分开来,同时它也是评估 VNH5019A 性能的绝佳工具。The Motherboard, based on the STM8 microcontroller, provides the logic section for monitoring and driving the VNH5019A pre-installed on the Daughterboard. STMicroelectronics provides a dedicated and user-friendly software with a Graphic User Interface (GUI) which enables the user to easily set the VNH5019A parameters, such as PWM and motor direction. The GUI also shows real-time device diagnostic information like current output evolution, battery voltage monitoring, board temperature, and much more.
