1. Product Overview
TYWRD3S is a low-power built-in Wi-Fi module that Hangzhou Tuya Inc has developed. It
consists of a highly integrated RF chip (RDA5981B) and several peripheral components, with a
built-in Wi-Fi network protocol stack and robust library functions. TYWRD3S is embedded with a
low-power ARM-CM4 MCU, 2 MB flash memory, 448 KB SRAM, and rich peripheral resources.
TYWRD3S is an RTOS platform that integrates all the function libraries of the Wi-Fi MAC and
TCP/IP protocols. You can develop built-in Wi-Fi products as required.
