Boardoza VNH5019ATR w-Enc Elite Breakout Board
The Boardoza VNH5019ATR W/ENC Elite Breakout Board is a high-power H-bridge motor driver breakout board built around the STMicroelectronics VNH5019A-E full-bridge motor driver IC. It is designed for automotive and industrial motor-control applications, supporting both high-current operation and encoder feedback. This version includes both terminal block and header connector interfaces, offering flexibility for rapid prototyping or permanent installations. The integrated 5 V-tolerant encoder interface provides three independent feedback channels (A, B, C) for closed-loop motion control. A dedicated heatsink enhances thermal performance and extends operational reliability under heavy loads.
