只有 PCB 板载天线接入方式。
在Wi-Fi模组上使用PCB板载天线时,为确保Wi-Fi性能的最优化,建议模组天线部分和其他金属件距离至少在15mm以上。
用户PCB板在天线区域勿走线甚至覆铜,以免影响天线性能。模组的PCB板载天线区域参考下面三种方式:1.天线位于板框外。2.天线位于板边,不要铺铜。3.天线位于板框内,区域挖空。上述几种方案的核心要点是:确保印制天线正下方或者正上方没有基板介质。确保印制天线的周围远离金属铜皮,这样可以在最大程度上保证天线的辐射效果。
PCB尺寸大小:16±0.35mm (W)×24±0.35mm (L) ×0.8±0.1mm (H)。
备注:默认的尺寸公差为+/- 0.35mm,关键尺寸如果客户有明确要求,请沟通后在规格书中进行明确的标定。

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”.
This device has got an FCC ID: 2ANDL-TYWE3SE. The end product must be labeled in a visible area with the following: “Contains Transmitter Module FCC ID: 2ANDL-TYWE3SE”.
This device is intended only for OEM integrators under the following conditions:
The antenna must be installed such that 20cm is maintained between the antenna and users, and the transmitter module may not be co-located with any other transmitter or antenna.
As long as the 2 conditions above are met, further transmitter tests will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed.
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.
