  • Highly integrated Wi-Fi SoC: powerful ESP8285 wifi chip, support 802.11 b/g/n, 2.4~2.4835GHz up to 72.2 Mbps, and Ap&Station mode
  • Ultra-low power technology: Five power states reduce non-essential functions and low energy consumption with DEEP_SLEEP mode supported 
  • Good WiFi  performance and fast response: can quickly wake up and transmit data packets within 2ms
  • Integrated high-speed cache: Helps improve system performance and optimize system memory
  • Starter-friendly: Plug-and-play Grove connector with detailed wiki provided.


Grove - UART WiFi V2.0(ESP8285) 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. 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.


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. For more detail about the version change, please refer to our wiki.


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.
