ESP8285 ESP-1 Serial Wireless WiFi Transmission Module
The WiFi module ESP-1 is manufactured by using a high-performance chip ESP8285.
This small chip is encapsulated an enhanced Tensilica’s L106 series 32-bit kernel CPU with a SRAM.
Thus, ESP8285 has the complete function Wi-Fi function; it not can be applied independent but can be used
as a slaver 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 benefiting improve the system performance but optimizing the store system. In addition, ESP8285 can be used as Wi-Fi adapter by SPI/SDIO or I2C/UART interface, when it is applied to other MCU design.
