L293D Motor Drive Shield – 4-Channel H-Bridge Motor Controller

L293D Motor Drive Shield for Arduino Uno, Mega, and Leonardo – 4-Channel H-Bridge Motor Controller

L293D Motor Shield is a monolithic integrated, high-voltage, high-current, 4-channel driver. Whether you are building a 4WD robot car or a precise CNC plotter, this shield simplifies your wiring and provides the power your motors need without risking your Arduino board.

L293D Motor Drive Shield Key Features & Benefits

• Multi-Motor Versatility: Features two L293D H-Bridge chipsets, enabling independent control of 4 bi-directional DC motors with 8-bit speed selection or 2 stepper motors (unipolar or bipolar).
• Jitter-Free Servo Support: Includes 2 dedicated connections for 5V “hobby” servos, connected to the Arduino’s high-resolution timer for smooth, precise movement.
• Advanced Power Management: Supports a wide voltage range (4.5V to 25V DC). It features a 2-pin terminal block for separate logic and motor power supplies, ensuring your Arduino stays protected from high-current motor draws.
• Safety First: Equipped with pull-down resistors to keep motors disabled during power-up and internal thermal shutdown protection to prevent damage from overheating.
• Easy Prototyping: Large terminal block connectors make it easy to hook up wires (18-26AWG) without soldering, and an on-board reset button keeps controls accessible.
