TYZS2是由涂鸦智能开发的一款低功耗嵌入式Zigbee模组。它由一颗高集成度的无线射频处理器芯片EFR32MG1B132F256GM48和少量外围器件构成,内嵌低功耗的32位ARM Cortex-M4内核,256KByte 闪存程序存储器,32KB RAM数据存储器 和丰富的外设资源。
TYZS2是一个能开发 Zigbee 应用的silicon平台模组,硬件内置 PA 和 DC-DC,软件上提供完整的 Zigbee 基础API。用户可以基于这些开发满足自己需求的嵌入式 Zigbee 产品。
TYZS2 功能原理如下图所示:
TYZS2 共有 2 排引脚,引脚间距为 2mm,共计 14 个对外 pin。
TYZS2 尺寸大小:14.8±0.35mm (W)×20.4±0.35mm (L) ×2.0±0.15mm (H)。TYZS2 尺寸图如下图所示:
引脚序号如下图所示。
接口引脚定义如下表所示。

默认 PCB 板载天线接入。
在 Zigbee 模组上使用 PCB 板载天线时,为确保无线性能的最优,建议模组天线部分和其他金属件的距离至少在 15mm 以上。
用户 PCB 板在天线区域周边勿走线和勿覆铜,以免影响天线辐射性能。建议天线区域的转接板镂空处理。
模组的 PCB 板载天线,区域参考 TYZS2 机械尺寸图。

FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this device.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
Note: This device has been tested and found to comply with the limits for a Class B digital device, according to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This device generates, uses, and can radiate radio frequency energy and, if not installed and used following the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
If this device does cause harmful interference to radio or television reception, which can be determined by turning the device off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Radiation Exposure Statement
This device complies with FCC radiation exposure limits set forth for an uncontrolled rolled environment. This device should be installed and operated with a minimum distance of 20cm between the radiator and your body.
Important Note
This radio module must not be installed to co-locate and operating simultaneously with other radios in the host system except following FCC multi-transmitter product procedures. Additional testing and device authorization may be required to operate simultaneously with other radios.
The availability of some specific channels and/or operational frequency bands are country dependent and are firmware programmed at the factory to match the intended destination. The firmware setting is not accessible by the end-user.
The host product manufacturer is responsible for compliance with any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.
The end-user manual shall include all required regulatory information/warnings as shown in this manual, including “This product must be installed and operated with a minimum distance of 20 cm between the radiator and user body”.
The RF module is considered as a limited modular transmitter according to FCC rules. Even though the RF module gets an FCC ID, the host product manufacturer can not use the FCC ID on the final product directly. In these circumstances, the host product manufacturer integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining the FCC authorization by a Class II permissive change application or a new application.
Declaration of Conformity European Notice
Hereby, Hangzhou Tuya Information Technology Co., Ltd declares that this module product is in compliance with essential requirements and other relevant provisions of Directive 2014/53/EU,2011/65/EU. A copy of the Declaration of conformity can be found at https://www.tuya.com.
This product must not be disposed of as normal household waste, in accordance with the EU directive for waste electrical and electronic equipment (WEEE-2012/19/EU). Instead, it should be disposed of by returning it to the point of sale, or to a municipal recycling collection point.
The device could be used with a separation distance of 20cm to the human body.
