Power supply: Two 18650 batteries (excluded out of package)Input: Ultrasonic module (HC-SR04)Motor: DC gear motorMotor drive: L9110S Motor Drive ModuleMicroprocessor: Type C NANO ATmega328p controller

Feature:

This smart car is developed based on the Type C development board and is equipped with the L9110S motor drive module, which can realize ultrasonic obstacle avoidance function.In addition, the output interface of the L9110S motor drive module adopts wiring terminals to facilitate the connection of the drive motor.The input terminal of the driver board can be connected to the pin on the expansion board through Dupont wire.The smart car adopts a welding-free installation design. Use copper posts and screws to secure the structure between the parts.The circuit connection between each module is made by Dupont wire, which is simple and convenient.The trolley uses 65mm plastic wheels and runs smoothly. We use DC geared motors with higher power.
