The DOIT Mini Ultra-Small size ESP-M3 Serial WiFi Module is manufactured by using a high-performance chip ESP8285. This small chip is encapsulated an enhanced Tensilicas L106 Diamond series 32-bit kernel CPU with an SRAM. Thus, ESP8285 has the complete function of Wi-Fi function; it not only can be applied independent but can be used as a slave working with other host CPU. When ESP8285 is applied as a slave, it can start from the onboard Flash.

The built-in high-speed buffer is not only benefiting improve the system performance but optimizing the store system. In addition, ESP8285 can be used as a Wi-Fi adapter by SPI/SDIO or I2C/UART interface, when it is applied to other MCU design.
