TYZS2 DATASHEET
Tuya Smart Zigbee Module
1. Product Overview
TYZS2 is a low power consumption module with built-in Zigbee connectivity TYZS2
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. TYZS2 include a 32-bit ARM Cortex-M4 CPU, 256K byte
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.
Figure 1 shows the block diagram of the TYZS2.

5. Antenna Information
5.1 Antenna Type
Antenna can be default connected using On-board PCB antenna.
5.2 Reduce Antenna Interference
While using the On-board PCB antenna, in order to have the best Zigbee performance, it’s
recommended to keep a minimum 15mm distance between the antenna part and the other metal
pieces.
User’s own PCBA design is recommended NOT to pass any wire, NOT do copper pour under
the region of the module’s antenna, to avoid interferences.

6.3 Production Guide

The storage for the delivered module should meet the following condition:
1. The anti-moisture bag should be kept in the environment with temperature < 30℃ and
humidity < 85% RH.
2. The expiration date is 6 months since the dry packaging products was sealed.
 Cautions:
1. All the operators should wear electrostatic ring in the whole process of production.
2. While operating, water and dirt should not have any contact with the modules.
