Product Overview
1.
WR3L is a low power-consuming built-in Wi-Fi module developed by Hangzhou Tuya
Information Technology Co., Ltd. It consists of a highly integrated radio frequency chip
(RTL8710BX) and an external flash chip, with a built-in Wi-Fi network protocol stack and robust
library functions. WR3L 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 robust peripheral resources.
WR3L 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.
