51 MCU smart car ultrasonic obstacle avoidance car tracking ranging robot programming DIY car kit

Product selling point:
1. Using high-quality materials, the quality is guaranteed
2. Ultrasonic distance measurement and obstacle avoidance, automatically rotate or back to avoid obstacles when encountering obstacles
3. The digital tube displays the current obstacle distance in real time, up to 5 meters
4. Introduce a new simulation design concept to make the circuit board more like a car chassis, a dedicated motor drive chip, control the forward and reverse rotation of the motor, and flexibly control the car’s forward, backward, in-situ rotation and other actions; the STC single-chip control system is closer to the people
5. A wide range of applications, training hands-on ability
parameter:
Working voltage: 5V
PCB size: 120*73mm
Power supply mode: 4 AAA batteries (not included in the delivery)
Working current: no-load less than 300mA (the motors are working but not walking)
The universal wheel version reduces the walking resistance of the car, saves power and lasts longer
