Product Details
2*L293D IC
Part No:L293D
Pin No: 16 pins
Package included：
2  x  L293D L293 L293B DIP/SOP Push-Pull Four-Channel Motor Driver IC
L293D Module
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

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 mnolithic integrated high voltage,high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoides, 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.
Package included：
1  x  For Arduino UNO MEGA2560 R3 Mini L293D Motor Drive Shield Module Expansion Board
L293D Sheild for ESP 12E
Power input:
Motor power supply (VM): 4.5V ~ 36V, can be powered separately
Control power (VIN): 4.5V ~ 9V (10VMAX), can be powered separately
Module provides short-circuit sub (short the VM and VIN), you can easily use one power (must 4.5V ~ 9V) while completing motor drive and control
Logic Operating current Iss: ≤60mA (Vi = L), ≤22mA (Vi = H)
Drive part of the work current Io: ≤1.2A
Maximum power dissipation: 4W (T = 90 ℃)
Control signal input level: High: 2.3V≤VIH≤VIN; Low: -0.3V≤VIL≤1.5V
Working temperature: -25 ℃ ~ + 125 ℃
Drive Type: Dual high-power H-bridge driver
ESP12E Dev Kit Control Port: D1, D3 (A motor); D2, D4 (B motor)
Expand two-way motor-driven, two-way direct drive motor
Onboard power switch
Motor power, control power separation; In the experiment, by short-circuiting block the merger,
the VIN and VM short, while power to the motor and the control board
Notice:
When inserted into the ESP-12E module,
please note the direction consistent with an expansion board antenna
The use of short modules that can simultaneously control board and motor.
