5G M.2 USB3接口板 我最近一直在尝试5G蜂窝模块，发现许多仅靠USB电源运行的M.2分支板（主要为4G模块设计）在传输过程中无法在峰值提供所需的电流。 我决定在KiCad中设计自己的双电源输入，Nano-SIM插槽和USB 3，以支持5G所需的数据速率。 我用我的一个移远 5G模块，我以前。 该设计非常符合RM500Q-GL模块的应用笔记建议，因此特别适合该模块。 特征 紧凑的尺寸，90mm x 40mm的电路板尺寸; 具有82mm x 32mm间隔的M2.5安装Kong USB 3.0 SuperSpeed可实现高5G数据速率 双电源输入。 USB 3.0 B（不建议用于大量数据，但适用于低端模块） 5-9V DC 5.5mm桶形插Kong（中心为正） 同时适合52mm和42mm M.2 B-Key模块 单个4FF Nano-SIM USIM插槽 模块重置按钮 模块WW

AzureWave Technologies, Inc. introduces the pioneer of the IEEE 802.11a/b/g/n/ac WIFI with Bluetooth,,,ShenZhen Office--Contact：JackyChen email：jackychen@flycastle.com phone No,:13510094765 4.1combo M.2 module ---AW-CM251NF. The AW-CM251NF IEEE 802.11 a/b/g/n/ac PCIE WIFI with Bluetooth 4.1 combo M.2 module is a highly integrated wireless local area network (WLAN) solution to let users enjoy the digital content through the latest wireless technology without using the extra cables and cords. It combines with Bluetooth 4.1 and provides a complete 2.4GHz Bluetooth system which is fully compliant to Bluetooth 4.1 and v2.1 that supports EDR of 2Mbps and 3Mbps for data and audio communications. It enables a high performance, cost effective, low power, compact solution that easily fits onto the PCI Express and USB M.2 module. Compliant with the IEEE 802.11a/b/g/n/ac standard, AW-CM251NF uses Direct Sequence Spread Spectrum (DSSS), Orthogonal Frequency Division Multiplexing (OFDM), BPSK,QPSK, CCK and QAM baseband modulation technologies. A high level of integration and full implementation of the power management functions specified in the IEEE 802.11 standard minimize system power requirements by using AW-CM251NF. AW-CM251NF module adopts QCA9377 single chip solution. The module design is based on the QCA9377 solution.

PCIe_M.2(NGFF)_Electromechanical_Spec_Rev1.0_Final

ORCAD格式的NGFF金手指原理图库，形象，准确,节省你建库与check标准的时间。

很多主板上的M.2接口都是SATA与NVME复用， 即插入NVME硬盘或无线网卡，走pcie信号，插入NGFF的硬盘走SATA信号。 这张对比表则是2个不同信号总线的针脚定义，供开发或主板维修使用。

PCI Express M.2 specification-Revision 0.7, Version 1.0,November 27, 2012, The M.2M.2 form factor is used for Mobile Add-In cards. The M.2 is a natural transition from the Mini Card and Half-Mini Card to a smaller form factor in both size and volume. The M.2 is a family of form factors that will enable expansion, contraction, and higher integration of functions onto a single form factor module solution. The key target for M.2 is to be significantly smaller in the XYZ and overall volume of the Half-Mini Card used today in mobile platforms in preparation for the very thin computing platforms (for example; Notebook, Tablet/Slate platforms) that require a much smaller solution.
