Product Description

Basically an ESP8285module is an ESP8266 Module with additional 1 MB of Flash memory and the ESP8285 can evenbear high temperature upto 125℃(the one for ESP8266 is just 85℃).More important, the code programmed in ESP8266 can also be used for ESP8285. 

The core processor ofthe ESP8285 M4 IoT module uses the cost-effective chipESP8285. The chip integrates an enhanced version of Tensilica's L106 DiamondSeries 32-bit core processor in a smaller package with on-chip SRAM. TheESP8285 has a full Wi-Fi network capability that can be used independently oras a slave to other host MCUs. When the ESP8285 hosts an application, it can belaunched directly from external Flash. The built-in cache helps improve systemperformance and optimizes the storage system. In addition, the ESP8285 can beused as a Wi-Fi adapter via the SPI/SDIO interface or I2C/UART port for anymicrocontroller-based design.

The ESP8285 M4wifi module supports the standard IEEE 802.11 b/g/n/e/i protocol andthe full TCP/IP protocol stack. Users can use this module to add networkingcapabilities to existing devices or to build separate network controllers. TheESP-M4 module provides Zui's great utility at low cost, providing unlimitedpossibilities for Wi-Fi functionality to be embedded in other systems.

The main technicalparameters of the module are as follows:
