ESP8266 ESP-01S 4MB Serial WIFI Wireless Transceiver Module

Feature:
This is WiFi serial transceiver module, based on ESP8266 SoC.
The SOC has Integrated TCP/IP protocol stack.
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.
Spec:
802.11 b/g/n
LWIP agreement
Support 3 modes: AP, STA, AP + STA
Perfect and simple AT commands
4MB Flash: XMC0H32BHIG/XM25QH32CJIG by random
