🔌 Mini 4-Channel L293D Motor Drive Shield
A compact motor driver board built around the L293D quad half-H driver. It plugs onto an Arduino UNO or MEGA 2560 and can run four DC motors or two stepper motors, with direction and speed controlled from your sketch.
✨ Key Features
- Four motor channels in a small, stackable shield footprint
- Drives 4 DC motors or 2 bipolar stepper motors
• L293D outputs with built-in flyback diodes
- Screw terminal for motor connections (A−, A+, B−, B+, GND, VIN)
- Separate motor supply input for higher-voltage motors
- Onboard decoupling capacitors for stable operation
🔬 Specifications
- Driver IC: L293D, quad half-H bridge
- Channels: 4
- Motor supply: up to 36V DC (L293D limit)
- Output current: ~600 mA continuous per channel, ~1.2 A peak
- Logic supply: 5V from the Arduino
- Control: direction pins plus PWM for speed
- Mounting: Arduino UNO/MEGA header spacing
🧰 Perfect for
• Small robot cars and tank chassis
• 4WD and mecanum robot platforms
• Bipolar stepper motor projects
- Conveyor, turntable and actuator prototypes
• Arduino learning projects
Tip: the L293D drops a few volts internally, so choose a motor supply with some headroom and add a heatsink if the chip gets hot.
