ESP8266 TUYA TYWE3S Wireless Networking Wifi Module PCB Assembly Description
TYWE3S is a low-power embedded Wi-Fi module developed by Hangzhou Tuya technology co., LTD. It consists of a highly integrated radio frequency chip ESP8266 and a handful of peripheral components, with a built-in Wi-Fi network protocol stack and rich library functions. TYWE3S is built in low-power 32-bit CPU, 1Mbyte flash memory, 50KB SRAM and rich peripheral resources.
TYWE3S is a RTOS platform that integrates all Wi-Fi MAC and TCP/IP protocol libraries. Users can develop embedded Wi-Fi products that meet their needs based on these developments.
The functional diagram of TYWE3S is shown in Figure 1:

Instructions:P indicates the power pin,I/O means input and output pins,AI represents the analog input pin. RST is just a module hardware reset pin, can't clear WiFi distribution network. (1):This pin can only be used as an ADC port, can not be used as a normol IO port,need to be suspended when not in use. When used ad an ADC input,input voltage range is limited to 0~1.0V (2):UARTO is the user serial port,when the module is powered om, serial port has information output,user can ignore.
