Opis

Introduction
L298P Shield DC motor driver adopts the L298P driver chip wich is exclusively made for large-power motor. It can drive 2 DC motors directly with a drive current reaching 2A. The motor output is equipped with eight high-speed schottky diode as protection. This driver carries neat circuit layout and bonded components, in addition, the multi-layer design enables it to be plugged to Aduino directly.
L298P Shield DC motor driver carries PWM mode. The motor can be powered via Aduino VIN input or terminal input on the driver, which are switchable by jumper.
