1. Product Overview

The TYZS15 is a low-power embedded Zigbee module developed by Hangzhou Tuya

Information Technology Co., Ltd. The module consists of a EFR32 highly integrated wireless RF

processor chip and a small number of peripheral devices. It has a built-in 802.15.4 PHY/MAC

Zigbee network protocol and a large number of library functions. The TYZS15 embeds a low-

power 32-bit ARM Cortex-M4 core, 512KByte Flash program memory, 64KB RAM data

memory, and a wealth of peripheral resources.

The TYZS15 is a FreeRTOS platform that gathers all Zigbee MAC and TCP/IP libraries into

one place. It enables users to build on the product and develop embedded Zigbee products that suit

their individual needs.
