ESP-M1 is encapsulated by the high performance chip ESP8285, which is equal to ESP8266 chip plus 1M Flash. ESP8285 has the full and complete WiFi function, which can used independently and also used as a slaver with other Hoster MCU, which can start directly from the out-built Flash. In addition, the built-in high-speed buffer is 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.
