This motor driver shield is based on an L293D motor driver chip which is designed to provide bidirectional drive currents of up to 1.2 A on each bridge with thermal shutdown protection at voltages from 4.5 V to 36 V.
This motor driver expansion board is based on the L293D chip which is designed to drive up to 4 bidirectional DC motors with individual 8-bit speed selection. It can also drive 2 stepper motors (unipolar or bipolar), single coil or double coil, interleaved or micro-stepping. It contains 4 H-bridges which provide up to 0.6 A per bridge (1.2A peak) at voltages from 4.5 V to 36 V. This shield has pull-down resistors to keep the motors disabled during power up. It also features a 2-pin terminal block to ensure separate logic and motor external power supplies. This expansion board is compatible with Arduino Mega, Diecimila, and Duemilanove. This motor driver shield is capable of driving:
- L293D motor driver chip
- Four H-bridges
- Terminal blocks for power supply and DC motors
- Reset button
- Big terminal block connectors (10-22 AWG)
- PCB Size: 69 x 53 mm
- 2 connections for 5V ‘hobby’ servos connected to the Arduino’s high-resolution dedicated timer
- 4 H-Bridges: L293D chipset provides 0.6A per bridge (1.2A peak) with thermal shutdown protection and internal kickback protection diodes.
- Can run motors on 4.5VDC to 25VDC.
- Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution)
- Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, or interleaved stepping.
How many motors can use with this shield?
You can use 2 DC servos that run on 5V and up to 4 DC motors or 2 stepper motors (or 1
stepper and up to 2 DC motors)
What is the LED for?
- The LED indicates the DC/Stepper motor power supply is working. If it is not lit, then the DC/Stepper motors will not run. The servo ports are 5V powered and do not use the DC motor supply
Applications of Motor Driver Shield L293D:
