Product description
Pololu Dual VNH5019 Motor Driver Shield for Arduino R3/R4 is a motor driver shield for controlling two brushed DC motors. The board is based on two ST VNH5019 motor driver ICs and supports supply voltages from 5.5 to 24 V. Each channel can deliver up to 12 A continuously (30 A peak), or both channels can be connected in parallel to drive a single motor with up to 24 A continuously (60 A peak). The board features current sensing, PWM support up to 20 kHz, and reverse-voltage protection. An Arduino library is available for quick integration.
