TYZS5 Module

Scope of application

This topic describes relevant information about the TYZS5 module during MCU connection development.

TYZS5 is a low power embedded Zigbee module developed by Tuya Smart. The module consists of a highly integrated radio-frequency identification (RFID) chip EFR32MG13P732F512GM48-C and a few peripheral components, with a built-in 802.15.4 PHY/MAC Zigbee network protocol stack and various library functions. TYZS5 also has a low power 32-bit ARM Cortex-M4 processor, 512 KB flash, 64 KB RAM, and rich peripheral resources.

TYZS5 is a FreeRTOS platform. You can develop your own embedded Zigbee products. For more information, see TYZS5 Module Datasheet.

Design specification

• Module power supply:

  • The maximum transmitting power consumption of the module is about 118 mA. It is recommended that the supply current of the 3.3 V module should exceed 200 mA, and the total capacity of the external filter capacitor should exceed 10 uF.
  • In the PCB layout, the filter capacitor at the power input pin shall be arranged near the power supply pin.

• Module pin:

  • When TYZS5 is used as a gateway module, you can see the module datasheet for the pin connection.

• Radio frequency (RF) of the module:

  • The module has a PCB onboard antenna by default.
  • When a PCB onboard antenna is used in the Zigbee module, it is recommended that the distance between the module antenna and other metal parts should be at least 15 mm, in order to optimize the wireless performance. Wiring and copper pour are not allowed in the antenna area of the PCB, in order not to affect the antenna performance. It is recommended to hollow out the adapter board in the antenna area.
