TYZS15 Reset & Teardown (FCC ID 2ANDL-TYZS15)

Version1.0.02
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.
