Wi-Fi Module UserManual
1. Product Overview
TYWE3L is a low power consumption module with built-in Wi-Fi connectivity solution
designed by HangZhouTuya Information Technology Corporation. The Wi-Fi Module consists of
a highly integrated wireless radio chip ESP8266 and some extra component that has been
programed with Wi-Fi network protocol and plenty of software examples.TYWE3L include a 32-
bit CPU, 1M byte flash, 50k SRAM and various peripheral resources.
TYWE3L is a 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.
Figure 1 shows the block diagram of the TYWE3L.

Note: S: Power supply pins; I/O: Digital input or output pins; AI: Analog input.RST pin is the
module hardware reset pin; it cannot eliminate module-pairing information.
(*1) This pin can only be used as ADC input, cannot use it as normal I/O. when not using,
just connect nothing. When used as ADC input, the input voltage range is 0~1.0V.
(*2) UART0 is serial port, during power on progress; this serial port will output something,
which can be ignored.
