TYWE2S is a low power consumption module with a built-in Wi-Fi connectivity solution. The Wi-Fi Module consists of a highly integrated wireless radio chip ESP8266EX and extra flash which has been programmed with Wi-Fi network protocol and plenty of software examples.TYWE1S also has an 32-bit CPU, 1M byte flash, 50k SRAM and various peripheral resources.
TYWE2S is an RTOS platform, embedded with all the Wi-Fi MAC and TCP/IP protocol function examples, users can customize their Wi-Fi product by using these software examples.
The figure shows the block diagram of the TYWE2S.

Instructions:P indicates the power pin,I/O means input and output pins,AI represents the analog input pin. RST is just module hardware reset pin, can't clear the WiFi distribution network. (1): This pin can only be used as an ADC port, can not be used as a normal IO port, need to be suspended when not in use. When used to ad an ADC input, the 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, the user can ignore.Pin Number Symbol IO type Function - IO4 I/O GPIO_04 - IO13 I/O GPIO_13 - IO2 I/O UART0_TXD(Module information print port) - RST I/O Reset pin - IO5 I/O GPIO_05 - IO0 I/O IO0 participates in the module startup when the module is suspended, the module enters the normal running state.
Instructions:I/O means input and output pins. I/O0 is left floating, the module is running normally, IO0 is low level, and the module is in firmware burning state. A test pin is not recommended.
