Tuya Smart Wi-Fi Module 
1 Product Overview 
WR6 is a low power-c onsuming built-i n Wi-F i module developed by Hangzhou Tuya Inc. It 
consists 
of a highly integrated RF microchip (W302 12E77H2) and an external flash chip, with a 
built-in Wi-Fi network protocol stack and robust library functions. WR6 also contains a low power-
consuming ARM CM4F, a WLAN MAC, a 1T1R WLAN, and the maximum basic frequency of 
125 MHz, and is embedded with a 256 KB SRAM, a 2 MB flash, and rich peripheral resources. 
WR6 is an RTOS platform that integrates all the function libraries of the Wi -Fi MAC and TCP/IP 
protocols. You can develop built-in Wi-Fi products as required.
