Overview

MotoMama.jpg

MotoMama is an H-Bridge motor driver shield bases on ST L298N chip. It is a high voltage, high current dual full-bridge driver which designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC motor and stepping motors. MotoMama is designed to be easy with other sensors or wireless modules.
