Ai-Thinker ESP-01 ESP8266 WiFi Module - PCB Antenna

Description
ESP8266 is a highly integrated chip designed for the needs of a new connected world. It provides 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 at runtime. Its high degree of on-chip integration ensures minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.
