1. Product Overview
TYZS2 is a low power co nsumption module with built-in Zigbee connectiv ity TYZS2
solution designed by Hangzhou Tuya Information Technology Co., Ltd. The Zig bee Module
consists of a highly integrated wireless radio chip EFR32MG1 B132 and some extra
component that has been programed with Zigbee network protocol 802.15.4 PHY/MAC and
plenty of software examples. TYZS2 include a 32-bit ARM Cortex-M4 CPU, 2 56K b yte
flash, 32k SRAM and various peripheral resources.
TYZS2 is a Free RTOS platform, embedded with all the Zigbee MAC and TCP/IP protocol
function examples, users can customize their Zigbee product by using these software examples.
