Mini L293D Motor Driver Shield — 4.5–25V, 600mA/ch, Arduino UNO & Mega 2560

Mini L293D Motor Driver Shield — 4.5–25V, 600mA/ch, Arduino UNO & Mega 2560

This mini L293D motor driver shield plugs directly into Arduino UNO or Mega 2560 pin headers, providing a dual H-bridge motor driver for controlling DC motors, stepper motors, and other inductive loads. The L293D IC provides 600mA continuous output per channel (1.2A peak) with built-in overtemperature protection and internal clamp diodes for inductive load protection. Input voltage 4.5–25V DC.

Specifications

• Driver IC: L293D (dual H-bridge)
• Input Voltage: DC 4.5V – 25V
• Output Current: 600mA per channel (continuous)
• Peak Current: 1.2A per channel (non-repetitive)
• Channels: 2 H-bridge channels (controls 2 DC motors or 1 stepper)
• Protection: Overtemperature shutdown, internal clamp diodes
• Logic Input: Up to 1.5V = logic “0” (TTL compatible)
• PWM Frequency: Up to 5kHz
• Compatible: Arduino UNO R3, Mega 2560

L293D vs L298N Motor Driver

• L293D (this shield): 600mA/ch, built-in clamp diodes, compact shield form — for small DC motors and steppers
• L298N module: 2A/ch, external diodes needed, larger module — for higher current motors

Typical Applications

• Arduino 2-wheel robot DC motor control
• Stepper motor control (bipolar, 4-wire)
• Small conveyor and actuator control
• Pan-tilt mechanism motor drive
• Arduino motor control learning project
