Product Overview

WR6 is a low power-consu

ming built-in Wi-Fi

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.

WR6 Datasheet 5 Antenna Information 5.1 Antenna Types onboard PCB antenna 5.2 Antenna Interference Reduction To ensure optimal Wi-Fi performance when the module uses an onboard PCB antenna, it is recommended that the antenna be at least 15 mm away from other metal parts. The following figures show five common antenna routing solutions. Solutions 1 and 2 have the best test performance, and the RF performance is the same as that of a single module.
