RTL8710BN TUYA WR3 Wifi Smart Product Module Develop Description

The WR3 is a low-power embedded Wi-Fi module developed by Hangzhou Tuya Information Technology Co., Ltd. The module consists of the highly integrated RTL8710BN chip and an external flash memory. It comes with a built-in Wi-Fi network protocol and a large number of library functions. The WR3 also includes low power ARM CM4F, WLAN MAC, 1T1R WLAN, a maximum frequency of 125MHz, built-in 256K SRAM, 1Mbyte flash, and a wealth of peripheral resources.

The WR3 is an RTOS platform that gathers all Wi-Fi MAC and TCP/IP libraries into one place. It enables users to build on the product and develop embedded Wi-Fi products that suit their individual needs.

The WR3 diagram is shown in Figure 1.1:
