PICAXE USB Download Cable Datasheet PDF Datasheet. The H-Bridge contains four half bridge drivers, enough to drive two DC motors in either forward or backward independently – perfect for making a roving robot! The SN754410 H-Bridge and L239D H-Bridge chips are pin-compatible, but this one integrates flyback protection diodes, making it simpler to wire up.ĭownload the L293D H-Bridge Datasheet (PDF)īuy the Texas Instruments L293D H-Bridge IC from Amazon, Adafruit, or Newark. The motor driver board is a pre-assembled circuit that includes the. Each channel is controlled by a TTL-compatible logic input and each pair of drivers (a full bridge) is equipped with an inhibit input which turns off all four transistors. Use an H-Bridge to drive a DC motor in two directions. The L293B and L293E are quad push-pull drivers capable of delivering output currents to 1A per channel.
