TUYA WiFi Module
1. Product Overview
TYWE3S 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. TYWE3S include a 32-bit CPU, 1M
byte flash, 50k SRAM and various peripheral resources.
TYWE3S 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.

2.2 Pin Definition
Table 1 shows the general pin attributes of TYWE3S
Table 1. The typical pin definition of TYWE3S
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.

5. Antenna Information
5.1 Antenna Type
Antenna can be connected only using On-board PCB antenna.
5.2 Reduce Antenna Interference
While using the On-board PCB antenna, in order to have the best Wi-Fi performance, it’s
recommended to keep a minimum 15mm distance between the antenna part and the other metal
User’s own PCBA design is recommended NOT to pass any wire, NOT do copper pour under
the region of the module’s antenna, to avoid interferences.
