Introduction
What is ESP8285
ESP8285=ESP8266+1M Flash application temperature up to 125→! First and foremost the code programmed in ESP8266 could be used for ESP8295 intact.
ESP-M2 module core processor is the high-performance chip ESP8285, which is equal to ESP8266 chip plus 1M Flash.
The chip ESP825 is encapsulated an advanced Tensilica’s L106 32-bit CPU, together with SRAM. ESP825 has the full and complete WiFi function, which can be used independently and also used as a slave with other Hoster MCU, which can start directly from the out-built Flash. In addition, the built-in high-speed buffer is a benefit for the system performance. Especially, ESP8285 can be used as a WiFi adapter by SPI/SDIO and/or I2C/UART interface, when it is applied to the other MCU design.
