What is ESP8285?

ESP8285 = ESP8266 + 1M Flash, so that it can withstand high temperatures up to 125 degrees Celsius! And the original ESP8266 source code program can be used to transplant.

ESP-M3 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 a complete Wi-Fi network function, both can be used independently, can also be used as a slave from other host MCU running. When the ESP8285 hosting application, 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, 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) high temperature, up to 125 ℃

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

It's little, it's simple, it does one thing and it does it really really well. Simple firmware with pretty much nothing to break, and just works without all the fumbling.
