1 Product Overview
WB2S is a low-power embedded Wi-Fi module that Tuya has developed. It consists of a
highly integrated RF chip (BK7231D) and several peripheral components, with an
embedded Wi-Fi network protocol stack and robust library functions. WB2S also
contains a low-power Arm Cortex-M4 microcontroller unit (MCU), 1T1R WLAN module,
256 KB static random-access memory (SRAM), 2 MB flash memory, and extensive
peripherals.
WB2S 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.
