Tuya Zigbee Module 
1. Product Overview
TYZS1 is a low power co nsumption module with built-in Zigbee connectivity 
solution designed by Hangzhou Tuya Information Technology Co., Ltd. The Zigbee Module 
consists of a highly integrated wireless radio chip EFR32MG1B132 and some extra 
component that has been programed with Zigbee network protocol 802.15.4 PHY/MAC and 
plenty of software examples. TYZS1 include a 32-bit ARM Cortex-M4 CPU, 256K byte 
flash, 32k SRAM and various peripheral resources. 
TYZS1 is a FreeRTOS platform, embedded with all the Zigbee MAC and TCP/IP protocol 
function examples, users can customize their Zigbee product by using these software examples.
