This product uses Tuya WB3S module. WB3S is a low-power embedded Wi-Fi+BLE dual protocol module developed by Tuya Smart. It consists of a highly integrated wireless radio frequency chip BK7231T and a small number of peripheral devices. It has a built-in Wi-Fi network protocol stack and rich library functions. WB3S also includes a low-power 32-bit MCU, 1T1R WLAN, a maximum frequency of 120MHz, built-in 256K SRAM, 2Mbyte flash and rich peripheral resources. WB3S is an RTOS platform that integrates all Wi-Fi MAC and TCP/IP protocol function libraries. Users can develop embedded Wi-Fi products that meet their own needs based on these.
