REES52 ESP8266 Remote Serial Port WIFI Transceiver Wireless Module Esp-09 AP+STA Micro Controller Board Electronic Hobby Kit

ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area. ESP8266 with various interface, support UART, IIC, PWM, GPIO, ADC, etc., suitable for a variety of things networking applications ESP8266 supports three kinds of antenna interface form: board PCB antenna, IPEX interface and stamp hole interface. widely used in smart grid, smart transportation, intelligent furniture, handheld devices, industrial control, etc. PCB antenna and IPEX antenna can be directly used without adding any matching circuit. If design antenna on board, it need esp8266 stamp hole antenna with matching circuit reserved.
