1 PRODUCT OVERVIEW
1 Product Overview
WBR3T is a low-power embedded WiFi+BLE module that Tuya has developed. It
consists of a highly integrated wireless RF chip (RTL8720DN), a few peripherals, an
embedded WiFi network protocol stack, the BT network protocol, and varied library
functions. WBR3T has an embedded low-power 32-bit CPU, 512-KB static random-
access memory (SRAM), 4-MB flash memory, and rich peripherals. WBR3T is an
RTOS platform that integrates all function libraries of the WiFi MAC and TCP/IP pro-
tocols. You can develop embedded WiFi products as required. The functional block
diagram of WBR3T is shown as belows:
