Z2 芯片对上电时序有要求,在上电过程中 RST 引脚达到 1.62V 以后系统开始启动,这个时候 VCC 需要在 10ms 内达到 1.8V 以上。由于 RST 引脚有 RC 链路,故裸模组在 RST 达到 1.62V 的时候 VCC 已经远超过 1.8V。
Z2 芯片模组对接的电源驱动如果存在大电容的一些充放电情况下,若模组电压未完全放电到 0.6V 以下,模组再启动会有一定风险。要求模组 VCC_3.3V
供电引脚需要接 1K 的假负载用来快速释放电能。可参考下面的部分电源驱动链路。
只有外接单极子天线接入方式。
在 Zigbee 模组上使用单极子天线时,为确保 Zigbee 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。

ZTC 可选用 SMT 贴片式。
涂鸦出厂的贴片封装模组建议使用 SMT 机器贴片,拆开包装后建议在 24 小时内完成焊接,如果拆封后未使用完,建议放置在湿度不超过 10%RH 的干燥柜内,或重新进行真空包装并记录暴露时间。总暴露时间不超过 168 小时。
涂鸦出厂的模组存储条件如下:
防潮袋必须储存在温度 <40℃、湿度 <90%RH 的环境中。
干燥包装的产品,保质期为从包装密封之日起 12 个月的时间。
密封包装内装有湿度指示卡:
涂鸦出厂的模组当出现可能受潮的情况下需要进行烘烤:
烘烤参数如下:
在整个生产过程中请对模组进行静电放电(ESD)保护。
为了确保产品合格率,建议使用 SPI 和 AOI 测试设备来监控锡膏印刷和贴装品质。
请根据回流焊曲线图进行 SMT 贴片,峰值温度 245℃,回流焊温度曲线如下图所示:
A:温度轴
B:时间轴
C:合金液相线温度:217-220℃
D:升温斜率:1-3℃/S
E:恒温时间:60-120S,恒温温度:150-200℃
F:液相线以上时间:50-70S
G:峰值温度:235-245℃
H:降温斜率:1-4℃/S
注意:以上推荐曲线以 SAC305 合金焊膏为例。其他合金焊膏请按焊膏规格书推荐炉温曲线设置。

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-ZTC. The end product must be labeled in a visible area with the following: “Contains Transmitter Module FCC ID: 2ANDL-ZTC”.
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 2) 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.
