Take control of your multi-motor projects with the high-performance L293D Motor Driver Shield. Specifically designed as a plug-and-play expansion board for the Arduino Uno and Mega, this shield eliminates messy wiring layouts. It is an absolute favorite among STEM students and robotics hobbyists building 4WD smart cars, advanced robotic arms, or intricate mechanical projects.
Driven by two L293D driver chips and a 74HC595 shift register, this shield gives you the massive capacity to run up to 4 bi-directional DC motors, 2 stepper motors, and 2 servo motors simultaneously.
Key Features:
Multi-Motor Management: Controls up to 4 bi-directional DC motors with individual 8-bit speed selection, or up to 2 stepper motors (unipolar or bipolar).
Dedicated Servo Headers: Features 2 designated 3-pin headers tied directly to Arduino's high-resolution hardware timers (Timer 1) for smooth, jitter-free servo motor control.
Pull-Down Resistors: Keeps your connected motors disabled and stationary during system power-up to prevent sudden, erratic movements.
Onboard Power Isolation: Includes an external power input terminal block with a removable jumper configuration, allowing you to separate your high-voltage motor power supply from your Arduino logic supply safely.
Convenient Reset Button: Features an easily accessible onboard reset button to reboot your microcontroller without removing the shield overlay.
Technical Specifications:
Driver Chips: 2x L293D H-Bridge Motor Drivers & 1x 74HC595 Shift Register
Motor Supply Voltage (EXT_PWR): DC 4.5V to 25V
Current Capacity: 600mA per channel (1.2A peak output current per channel)
Thermal Protection: Automatic internal shutdown mechanism against overheating.
Compatibility: Native layout form-factor for Arduino Uno, Leonardo, and Mega boards.
