YLB1 是由涂鸦智能开发的一款低功耗嵌入式的单点蓝牙模组,不支持 Mesh。它主要由一个高集成度的蓝牙芯片 BK3432 和少量的外围电路构成。
YLB1 内置了蓝牙网络通信协议栈和丰富的库函数,还包含低功耗的 32 位 MCU、蓝牙 2.4G Radio、160Kbyte Flash 和 20Kbyte SRAM。
YLB1 共有 3 排引脚,引脚间距 1.25mm。
YLB1 尺寸大小:12±0.35mm (W)×18±0.35mm (L) ×2.8±0.15mm(H),其中 PCB 厚度 0.8mm±0.1 mm,如图所示:

YLB1 使用的是板载 PCB 天线,天线增益 0.2dBi。
为确保 RF 性能的最优化,建议模组天线部分和其他金属件的距离至少保持 15mm 以上。如果使用环境的天线周边包裹金属材料等,会极大地衰减无线信号,进而恶化射频性能。成品设计时,注意给天线区域预留出足够的空间。
PCB 推荐封装:
说明:默认的模组外形尺寸公差为 ±0.35 mm,关键尺寸公差 ±0.1 mm。
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。

FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with 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 equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment 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 equipment complies with FCC radiation exposure limits set forth for an uncontrolled rolled environment. This equipment 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 operate simultaneously with other radios in the host system except in accordance with FCC multi-transmitter product procedures. Additional testing and equipment authorization may be required to operate simultaneously with other radio.
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 from the human body.
