 L293D Motor Driver Control Shield for Arduino H bridge dual
L293D Motor Driver Control Shield for Arduino H bridge dual
MPN :
SKU : L293DS-G53S4
Stock : 19pcs
Price:PKR 400.00
L293D is a monolithic integrated, high voltage, high current, 4-channel driver.Basically this means using this chip you can use DC motors and power supplies of up to 36 Volts, thats some pretty big motors and the chip can supply a maximum current of 600mA per channel, the L293D chip is also what’s known as a type of H-Bridge. The H-Bridge is typically an electrical circuit that enables a voltage to be applied across a load in either direction to an output, e.g. motor.


- 2 interface for 5V Servo connected to the  high-resolution dedicated timer - no jitter!
- Can drive 4 DC motors or 2 stepper motors or 2 Servo
- Up to 4 bi-directional DC motors with individual 8-bit speed selection
- Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping.
- 4 H-Bridges: per bridge provides 0.6A (1.2A peak current) with thermal protection, can run motors on 4.5V to 36V DC
- Pull down resistors keep motors disabled during power-up
- reset button
- 2 external terminal power interface, for seperate logic/motor supplies
- Tested compatible for  Mega, Diecimila & Duemilanove

Here is a design for a full-featured motor shield that will be able to power many simple to medium-complexity projects.


4 H-Bridges: L293D chipset provides 0.6A per bridge (1.2A peak) with thermal shutdown protection, 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.
Pull down resistors keep motors disabled during power-up
Big terminal block connectors to easily hook up wires (18-26AWG) and power
Arduino reset button brought up top
2-pin terminal block and jumper to connect external power, for separate logic/motor supplies
Tested compatible with Arduino Mega 1280 & 2560, Diecimila, Duemilanove, and UNO


L293D motor shield, the input voltage DC4.5-25V
600mA OUTPUT CURRENT CAPABILITY PER CHANNEL
1.2A PEAK OUTPUT CURRENT (non repetitive)PER CHANNEL
ENABLE FACILITY
OVERTEMPERATURE PROTECTION
LOGICAL "0" INPUT VOLTAGE UP TO 1.5 V(HIGH NOISE IMMUNITY)
INTERNAL CLAMP DIODES


The Device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoids, DC


and stepping motors) and switching power transistors .To simplify use as two bridges each pair of channels is equipped with an enable input. A separate supply input is provided for the logic, allowing operation at a lower voltage and internal clamp diodes are included. This device is suitable for use in switching applications at frequencies up to 5 kHz.
