Product Overview

WR6 Dat

asheet

WR6 is a low power-consu

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.
