You can use it just like an ESP8266, it's the same processor and WiFi The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well.

Because the ESP8285 contains the FLASH memory inside the chip, the modules that use it are much smaller and a little less expensive too. ESP8285 has a complete Wi-Fi network function, both can be used independently, can also be used as a slave by other running MCU hosts. When the ESP8285 hosting application, it can be started directly from the external Flash. built-in cache memory facilitates system performance and optimizes storage systems. in addition, ESP8285 only through the SPI / SDIO interface or I2C / UART port can be used as a Wi-Fi adapter connection, applied to any micro-controller-based design.
