GENERAL DESCRIPTION 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. Pairing Information Exchange Figure 1, shows the top view of the M.2 Card mounted with WE866Cx module. Figure 1: M.2 Card Top View The card has no components on the bottom side. Mounting Example on MT IFBD (MTB) Figure 2, shows the M.2 plugged into the MTB. 1VV0301533 Rev. 3 Page 7 of 21 Not Subject to NDA 2022-03-10 WE866Cx M.2 Interface Adapter Hardware User Guide Figure 2: M.2 Plugged into MTB Detailed Description This section provides details about the M.2 card, its connections and specifications. 2.3.1. M.2 Specification 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. 1VV0301533 Rev. 3 Page 8 of 21 Not Subject to NDA 2022-03-10 WE866Cx M.2 Interface Adapter Hardware User Guide 2.3.2. WE866Cx M.2 Card 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. 1VV0301533 Rev. 3 Page 9 of 21 Not Subject to NDA 2022-03-10 WE866Cx M.2 Interface Adapter Hardware User Guide 3.

The use of this product may be dangerous and has to be avoided in areas where: • • it can interfere with other electronic devices, particularly in environments such as hospitals, airports, aircrafts, etc. there is a risk of explosion such as gasoline stations, oil refineries, etc. It is the responsibility of the user to enforce the country regulation and the specific environment regulation. Do not disassemble the product; any mark of tampering will compromise the warranty validity. We recommend following the instructions of the hardware user guides for correct wiring of the product. The product has to be supplied with a stabilized voltage source and the wiring has to be conformed to the security and fire prevention regulations. The product has to be handled with care, avoiding any contact with the pins because electrostatic discharges may damage the product itself. Same cautions have to be taken for the SIM, checking carefully the instruction for its use. Do not insert or remove the SIM when the product is in power saving mode. The system integrator is responsible for the functioning of the final product. Therefore, the external components of the module, as well as any project or installation issue, have to be handled with care. Any interference may cause the risk of disturbing the GSM network or external devices or having an impact on the security system. Should there be any doubt, please refer to the technical documentation and the regulations in force. Every module has to be equipped with a proper antenna with specific characteristics. The antenna has to be installed carefully in order to avoid any interference with other electronic devices and has to guarantee a minimum distance from the body (20 cm). In case this requirement cannot be satisfied, the system integrator has to assess the final product against the SAR regulation. The equipment is intended to be installed in a restricted area location. The equipment must be supplied by an external specific limited power source in compliance with the standard EN 62368-1:2014. The European Community provides some Directives for the electronic equipment introduced on the market.
