ESP-M3 is encapsulated by the high performance chip ESP8285, which is adequate to ESP8266 chip plus 1M Flash. The chip ESP825 is encapsulated an advanced Tensilica’s L106 32-bit CPU, alongside SRAM. ESP825 has the complete and complete WiFi function, which may used independently and alsoused as a slaver with other Hoster MCU, which may start directly from the out-built Flash. In addition, the built-in high-speed buffer is benefit for the system performance. Especially, ESP8285 are often used as a WiFi adapter by SPI/SDIO and/or I2C/UART interface, when it's applied to the opposite MCU design.
Features: Ultra-small size, Support serial to WiFi, Wireless transparent transmission, Long-distance transmission with ultra-low power, Support outboard antenna. Bearing high temperature to 125oC, compared to the 85oC for ESP8266.
ESP8285=ESP8266+1M Flash, chip feature1) size is ultra-small2) serial to WiFi3) wireless transmission4) long-range ultra-low-power consumption5) high temperature, up to 125oC) fully compatible with ESP8266, the esp8266 source code can be used for esp8285
