TYWE3S Module

WiFi module introduction–TYWE3S

1. Product Overview

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:
