Features:
The drive module can directly drive four DC motor, 4WD drive car on the chassis of choice. Drive battery, motor current up to 1A smart car only four 100-300mA is sufficient to meet the control needs. While leaving the Road stepper motor interface can drive the Road five-wire four-phase stepper motor or Road, two-phase four-wire stepper motor, very suitable for the precise control of demand.
There is the corresponding interface can be directly connected to the steering gear, infrared obstacle avoidance and other peripherals. While leaving the charger interface, bouncing switch hands into the charger to charge the rechargeable batteries. Very convenient!
The Quad DC motor driver module, using ST's original new L293D chip, SMT and high process stability, the use of high-quality aluminum electrolytic capacitors, the circuit stability. 4-way 3-16V DC motor can be driven directly and provides a 5V output interface (input low as 6V), you can give the the 5V microcontroller circuit system power supply (low ripple factor), support 3.3V MCU ARM control, you can easily control DC motor speed and direction can also control the 2-phase stepper motor, 5-wire 4-phase stepper motor. 4 car, smart car essential tool.
