1. Product Overview
TYWRD2S is a low-power embedded Wi-Fi module that Tuya has developed. It consists
of a highly integrated RF chip (RDA5981B) and several peripheral components, with an
embedded Wi-Fi network protocol stack and robust library functions. TYWRD2S is
embedded with a low-power Arm Cortex-M4 MCU, 2 MB flash memory, and 448 KB static
random-access memory (SRAM), and has extensive peripherals.
TYWRD2S is an RTOS platform that integrates all function libraries of the Wi-Fi MAC and
TCP/IP protocols. You can develop embedded Wi-Fi products as required.
