L293D Motor Drive Shield

• Up to 4 bi-directional DC motors with individual 8-bit speed selection
• Can run motors on 4.5V to 16V DC.
• Pull down resistors keep motors disabled during power-up

The L293D Motor Drive Shield 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 16 Volts, thats some pretty big motors and the chip can supply a maximum current of 600mA per channel.
