BPLCB 是由涂鸦智能开发的一款低功耗嵌入式的蓝牙模组。它主要由一个高集成度的蓝牙芯片 PHY6222 和少量的外围电路构成,内置了蓝牙网络通信协议栈和丰富的库函数。
BPLCB 还包含低功耗的 32 位 MCU、蓝牙 5.1/2.4G Radio、512KB flash、64Kbyte SRAM 和 2 个可复用的 IO 口。
BPLCB 有正反面共计五个引脚,用于插件式组装。
BPLCB 尺寸大小:7.5±0.35mm (W)×10.9±0.35mm (L) ×2.3±0.15mm(H)封装如图所示,其中 PCB 厚度1.0±0.1mm。

部分客户的磁吸灯应用方案,在使用中发现磁吸灯驱动 LED 的三根线上存在较强的辐射干扰,三根线靠近模组时,可能造成模组频繁离线或者近距离配网困难。因此,建议在驱动 LED 的三根线上各预留 10nF 对地电容,以减小驱动线对模组的辐射干扰。

BPLCB 使用的是外置单极子天线,具体增益及尺寸可根据客户需求进行定制。
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。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。
涂鸦出厂的直插式模组建议优先使用波峰焊接设备焊接,在无法使用波峰焊接设备焊接时才使用手工焊接,拆开包装后建议在 24 小时内完成焊接,否则需放置在湿度不超过 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。
焊接所需设备和材料:
烘烤所需仪器或设备:
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。
为了确保产品的良好品质,生产时需重点关注助焊剂的喷涂量,波峰高度,波峰焊锡缸内的锡渣和铜含量是否超标,波峰焊接治具开窗和治具厚度是否合适以及波峰焊接炉温曲线的合理性。
请参考波峰焊接炉温建议进行炉温设定,峰值温度 260℃±5℃,波峰焊接温度曲线如下图所示:

This device has got an FCC ID: 2ANDL-BT8C. The end product must be labeled in a visible area with the following: “Contains Transmitter Module FCC ID: 2ANDL-BPLCB”.
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.
