1 Product Overview

 

WBR3N  is  a  low

-

power  embedded  WiFi+BT  module  that  Tuya  has  developed.  It  consists  of  a 

highly integrated wireless RF chip (RTL8720CS), a few peripherals, an

 

embedded WiFi network protocol stack, the BT network protocol, and varied library

 

functions. WBR3N has an embedded low

-

power 32

-

bit CPU, 512 KB static randomaccess memory 

(SRAM), 4 MB flash memory, and rich peripherals. WBR3N is an

 

RTOS platform that integrates all function libraries of the WiFi MAC and TCP/IP protocols. You can 

develop embedded WiFi products as required.
