Thank you for your understanding and continued support.
Tiny WiFi module uses ESP8285 chip, which has complete and self-contained WiFi network functionality. So it can be regarded as a standalone application, also be run as slave from other host MCU. This chip integrated enhanced 32-bit core processors of Tensilica’s L106, and it has on-chip SRAM. The advantage of ESP8285 is both hardware and software are mature enough, and it has 1M Byte Flash inside. The main frequency can above 160 MHz, and the series rate can be as high as 4Mbps. It has GPIO, IIC, UART, PWM, ADC and some more interfaces. Completely compatible with ESP8266, so we can use original code.
This module can be used on smart home, such as domestic appliance, intelligent socket/lamp, baby monitors. In addition, it also can be applied on electronic industrial, such as sensor network, industrial wireless control product parameter module structure diagram and so on.
The distance of transmission is long.
The power consumption is low.
It can withstand high temperature above 125℃.
It can put antenna outside.
It supports various sleep modes, the standby power as low as 1.0mW.
It supports STA/AP/STA+AP working modes.
It has UART/GPIO/IIC/PWM/ADC interfaces.
It supports serial local upgrade and remote firmware upgrade (FOTA).
It supports Smart Config/Airkiss, and one key distribution network.
