ESP8285=ESP8266+1M Flash. Compared with the ESP8266, it can withstand temperatures up to 125 degrees Celsius! And the original ESP8266 source program can be used as it is.
The core processor of the ESP-M1/M2 module uses the cost-effective chip ESP8285. The chip integrates an enhanced version of Tensilica’s L106 Diamond Series 32-bit core processor in a smaller package with on-chip SRAM. The ESP8285 has a full Wi-Fi network capability that can be used independently or as a slave to other host MCUs. When the ESP8285 hosts an application, it can be launched directly from external Flash. The built-in cache helps improve system performance and optimizes the storage system. In addition, the ESP8285 can be used as a Wi-Fi adapter via the SPI/SDIO interface or I2C/UART port for any microcontroller-based design.
