WBR3 is a low-power embedded Wi-Fi+BT module that Tuya has developed. It consists of a highly integrated RF chip (RTL8720CF), with an embedded Wi-Fi network protocol stack and varied library functions.
Overview
* With the maximum CPU clock rate of 100MHz, WBR3 also contains a low-power KM4 microcontroller unit (MCU), WLAN MAC, a 1T1R WLAN module, 256-KB static random-access memory (SRAM), 2-MB flflash memory, and extensive peripherals.
* WBR3 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.
