Hangzhou Tuya Information Technology TYLC4 User Manual

TYLC4v1.0.0 User manual

1. 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.
