Swimming Pool Robot -4WD WiFi Remote Control Smart Car with Arduino Control Kit Highlights Generic Brand 4WD WiFi Remote Control Smart Car with Arduino Control Kit Description: Most of the parts are connected by screws, and some parts are designed with socket row insertion. Each interface corresponds to a socket, not connecting the cables one by one, which simplifies the installation and gives an elegant appearance. There are two general methods to control the car: remote control and local control (including point-to-point and relay via WiFi router). Support multiple functions: tracking, ultrasonic obstacle avoidance, tracking, etc. can be controlled by IR remote control and APP by remote control for mobile. You can change the status of modes at any time, such as remote control mode, obstacle avoidance mode, and follow mode by APP. Using NodeMCU motor driver board, expansion of output ports for control kit: SPI, UART, GPIO, AI and 3.3V power interfaces, 2-way motor expansion, then direct motor enable 2-way Flexibility - forward, backward, turn left, turn right, return motors High-speed motors and high-end tracks also allow it to move quickly anywhere. specification: Material: plastic Detailed product size: 220x160mm/8.66x6.30inch (length*width) Package includes: 1 set car chassis (with necessary accessories) 1 NodeMCU block NodeMCU motor driver board 1 block several binding line and screws
