Introduction
The M.2 Card provides the customer, the means to evaluate the WE866Cx Wi-Fi module capability, and an interface with the LE910Cx.
It is designed to interface the Telit LE910Cx module family on an IFBD with the Telit Generic Evaluation Board (EVB) and thus forming a complete Development Kit of LE910Cx.
The M.2, formerly known as the Next Generation Form Factor (NGFF), is a specification from 2013 for internally mounted computer expansion cards and associated connectors.
The Specification details the buses that can be exposed through the M.2 connector. The buses are PCI Express 3.0, Serial ATA (SATA) 3.0, and USB 3.0, which is backward compatible with USB 2.0. As a result, M.2 modules can integrate multiple functions, including the following device classes: Wi-Fi, Bluetooth, satellite navigation, near field communication (NFC), digital radio, Wireless Gigabit Alliance (WiGig), wireless WAN (WWAN), and solid-state drives (SSDs).
An M.2 module is installed into a mating connector provided by the host's circuit board, and a single mounting screw secures the module into place. Components may be mounted on either side of the module, with the actual module type limiting how thick the components can be; the maximum allowable thickness of components is 1.5 mm per side. Different host-side connectors are used for single and double-sided M.2 modules, providing different amounts of space between the M.2 expansion card and the host's PCB.
The PCB of an M.2 module provides a 75 - position edge connector. Depending on the type of module, certain pin positions are removed to present one or more keying notches.
The WE866Cx M.2 card follows the below M.2 specification:
SDIO based Socket 1 2230 size type Key type E
This form - factor card specification is intended to support Wireless Connectivity devices including combinations of Wi - Fi, BT, NFC, and/or GNSS.
The card includes a U.FL miniature RF connector for connecting a compatible Wi - Fi antenna.
