SPECIFICATIONS

The ESP32-CAM video car is a smart car based on the ESP32-CAM module. It has video transmission and remote control functions. The ESP32-CAM module is an IoT development board that integrates a camera and a Wi-Fi module, which is able to transmit images captured by the camera in real time. Combined with other electronic modules and components, a powerful video car can be built.
What’s more, it provides four GPIO ports for expanding sensors and modules, and Lego holes on both sides of the driver board make the car’s gameplay more imaginative.
Parameters
USB voltage / charging voltage: 5V
Working voltage: 5V/3.3V
Battery voltage: 3.7V
Data transmission method: WiFi
Operating temperature: –10 to +65 degrees Celsius
Features
(1). The car integrates the download circuit of the ESP32-CAM development board into a motor driver board, which greatly improves the convenience of using the ESP32-CAM.
(2). We have integrated the charging function of the car into the motor driver board.
(3). Simple assembly: we only need to assemble the directional wheel and wheels.
(4). Strong scalability: we use IIC to control the motor. The saved IO ports are used to expand the gameplay by itself, and holes are reserved for building Lego
