Last Updated on : 2021-06-17 06:46:52download

TY004 is a low-power Iot Wi-Fi module developed by Hangzhou Tuya Information Technology Co., Ltd. It consists of a highly integrated radio frequency chip RTL872CS chip, which has built-in Wi-Fi network protocol stack and rich library functions. The module is packaged with stamp holes around it, meeting low power consumption IPC/doorbell/camera lights /Smart home appliances and other wireless control fields, but also suitable for smart home products that transmit large amounts of data.
