1. ESP8266 has powerful on-board processing and storage functions, which enables it to integrate with sensors and other application-specific devices through its GPIO, minimizing the load of up-front development and runtime. 2. Its of on-chip integration allows for minimal external circuitry, and the entire solution, including the front-end module, is designed to occupy the smallest PCB area. 3. DIY smart car: With the motor or servo expansion board, you can DIY smart robots, such as remote control cars, tank chassis, etc. Product Specification model: ESP8266 WIFI development board Mounting Type: Through Hole Application field: industrial grade Product Series: Development Board memory: 32MB size: 10.5 x 5.3cm Material: Plastic colour: black Package Contents: 1 x Development board 1 x Mini cable Only the above package content, other products are not included.
