Product Overview

        TYLC4  is  a  low-power  embedded  Wi-Fi  module  developed  by  Hangzhou  Tuya  Information 
Technology  Co.,  Ltd.,  which  consists  of  a  highly  integrated  RF  chip  ESP8266  and  a  few 
peripheral components with built-in Wi-Fi network protocol stack and abundant library functions. 
TYLC4  is  embedded  with  low  power  32-bit  CPU,  1  Mbyte  flash  memory  and  rich  peripheral 
resources.

 

TYLC4  is  a  RTOS  platform  which  integrates  all  the  function  libraries  of  Wi-Fi  MAC  and 

TCP/IP protocol, base on which, users are enabled to develop embedded Wi-Fi products according 
to their specific requirements.
