Giới thiệu Bảng Mạch L293D Cho Arduino Duemilanove Mega2560 Uno R3
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 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 interface for 5V Servo connected to the Arduino's high-resolution dedicated timer - no jitter. Can drive 4 DC motors or 2 stepper motors or 2 Servo. color: black 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. Size: 6.8cm x 5.5cm x 2cm - 2.68inch x 2.17inch x 0.79inch. Material: PCB Package List: 1xL293D Motor drive ule Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
