ESP-M1 Core module is The high performance esp8285 chip, which is equal to the esp8266 chip plus 1 m Flash. The esp825 chip is encapsulated in an advanced tensile processor, along with SRAM. Esp825 has the complete and complete WiFi connection, which can be used independently and alsosed as a slaver with other hoster MCUs, which can start directly from the construction flash. In addition, the built-in high-speed buffer benefits from system performance. Especially, esp8285 can be used as WiFi adapter by SPI / sdio and / or I2C / UART interface, when applied to the other MCU design.
