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.
