1 PRODUCT OVERVIEW
1 Product Overview
TYWE3L is a low power consumption module with built-in Wi-Fi connectivity solution
designed by HangZhou Tuya 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 re-
sources.
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 some-
thing, which can be ignored.
