WBR1D-IPEX Datasheet

1 Product Overview

WBR1D-IPEX is a low-power embedded Wi-Fi and Bluetooth module that Tuya has

developed. It consists of a highly integrated RF chip (RTL8720DN) and several peripheral

components, with an embedded Wi-Fi network protocol stack, Bluetooth network protocol,

and robust library functions. WBR1D-IPEX is embedded with a low-power 32-bit CPU,

512 KB static random-access memory (SRAM), and 4 MB flash memory, and has

extensive peripherals.

WBR1D-IPEX is an RTOS platform that integrates all function libraries of the Wi-Fi MAC

and TCP/IP protocols. You can develop embedded Wi-Fi products as required.
