描述
Grove – Uart Wifi ESP8266 串口 WIFI 通訊模組
Grove – UART WiFi是一款採用無處不在的ESP8266 IoT SoC的串行收發器模塊。通過集成的TCP / IP協議棧，該模塊可讓您的微控制器僅通過幾行代碼即可與WiFi網絡進行交互。每個ESP8266模塊都預編程有一個AT命令集固件，這意味著您可以發送簡單的文本命令來控制設備。SoC集成了WEP，WPA / WPA2，TKIP，AES和WAPI引擎，可以充當與DHCP的接入點，可以加入現有的WiFi網絡，並具有可配置的MAC和IP地址。

Grove – UART WiFi is a serial transceiver module featuring the ubiquitous ESP8266 IoT SoC. With integrated TCP/IP protocol stack, this module lets your microcontroller interact with WiFi networks with only a few lines of code. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning you can send simple text commands to control the device. The SoC features integrated WEP, WPA/WPA2, TKIP, AES, and WAPI engines, can act as an access point with DHCP, can join existing WiFi networks and has configurable MAC and IP addresses. Features
