WIFI chip ESP8285 - ESP8266 upgrade

ESP8285=ESP8266+1M Flash。 

Compared with ESP8266, it has a high temperature resistance of 125 degrees celsius! And the original ESP8266 source program can be transplanted intact.

ESP-M1 / M2 module core processor using cost-effective chip ESP8285. The chip integrates the enhanced version of the Tensilica's L106 Diamond 32-bit core processor with on-chip SRAM in a smaller package.

ESP8285 has full Wi-Fi

Network functions, not only can be applied independently, but also can be used as a slave to run on other host MCUs. When the ESP8285 hosting application, can be started directly from the external Flash. Built-in cache memory is not only conducive to improving system performance, but also optimize the storage system. In addition, ESP8285 can be used as a Wi-Fi adapter  only through the SPI / SDIO interface or I2C / UART port , applied to any microcontroller-based design.

1) the volume is ultra-small;

2) serial to WiFi;

3) wireless transmission;

4) long-range ultra-low power consumption;

5) can be an external antenna. 

6) high temperature, up to 125 ℃

7) compatible with ESP8266, the source can be used to transplant.
