seeed studio Grove UART WiFi Module V2(ESP8285) UART Interface 3V/5V Open Source, Compatible with Board Arduino/Seeeduino
  • 【Specification】Operating Voltage: 3V/5V. This module is a serial transceiver module featuring the ubiquitous ESP8285 IoT SoC. With an integrated TCP/IP protocol stack, this module lets your microcontroller interact with WiFi networks with only a few lines of code.
  • 【Simple to 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.
  • 【Widely Applications】ESP8285 can perform either as a standalone application or as a slave to a host MCU. When ESP8285 hosts the application, it promptly boots up from the flash. The integrated high-speed cache helps to increase system performance and optimize system memory. Also, ESP8285 can be applied to any micro-controller design as a Wi-Fi adaptor through SPI/SDIO or I2C/UART interfaces.
  • 【Various Main Boards Support】Grove connector compatible, it can easily connect to Arduino, Seeeduino. (It's the upgrade version of Grove UART WiFi, we changed the ESP8266 into ESP8285 and made some other adjustments to make it more stable and lighter.)
  • 【Tech Support】Visit >>Seeed Wiki<< from Seeed Studio official page for more tech support and tutorials.
