The L293D is a monolithic integrated high voltage and current 4-channel driver circuit. This means that with this chip you can use DC motors and power supplies up to 36 Volts, with a maximum current of 600mA per channel. The L293D chip belongs to the H-Bridge category, allowing voltage to be applied to a load in any direction, e.g., on a motor.

• 2 ports for 5V Servo connected with the high-resolution dedicated timer - no jitter!
• Can drive 4 DC motors or 2 stepper motors or 2 Servo.
• Up to 4 bidirectional DC motors with individual 8-bit speed selection.
• Up to 2 stepper motors (unipolar or bipolar) with single or double coil or microstepping.
• 4 H-Bridges: each bridge provides 0.6A (1.2A peak current) with thermal protection, can run motors on 4.5V to 36V DC.
• Pull down compensation keeps motors disabled during startup.
• Reset button.
• 2 external power supply connectors, for separate logic/motor supplies.
