- Basically this means using this chip you can use DC motors and power supplies of up to 12 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 connections for 5V 'hobby' servos connected to the Arduino's 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 12V 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 Arduino Mega, Diecimila & Duemilanove.
Power for the motors can be supplied from the Arduino boards DC Jack (normally 9V) or from the 2-pin EXT-PWR terminal block.
If you are supplying power from the EXT_PWR terminal block you should remove the PWR jumper or you could damage the shield and the Arduino board.
- Please note that this item does not come with an Arduino (you'll need one to use with the shield).
- The shield now comes with all the components soldered on and tested and have headers installed.
