Software related issues, like the Linux driver, are not addressed. There are separate documents for that. 2.1 Benefits of Using an M.2 Module to get Wi-Fi/BT Connectivity There are several benefit to use an M.2 module to add connectivity to an embedded design:   Drop-in, certified solution! Modular and flexible approach to evaluate different Wi-Fi/BT solutions - with different tradeoffs around performance, cost, power consumption, longevity, etc. Access to maintained software drivers (Linux) with responsive support from Murata. Supported by Embedded Artists' Developer's Kits for i.MX 6/7/8 development, including advanced debugging support on carrier boards One component to buy, instead of 50+ No RF expertise is required Developed in close collaboration with Murata and Cypress      2.2 More M.2 Related Information For more information about the M.2 standard and Embedded Artists' adaptation, see: M.2 Primer For more general information about the M.2 standard, see: https://en.wikipedia.org/wiki/M.2 The official M.2 specification (PCI Express M.2 Specification) is available from: www.pcisig.com 2.3 ESD Precaution and Handling Please note that the M.2 module come without any case/box and all components are exposed for finger touches – and therefore extra attention must be paid to ESD (electrostatic discharge) precaution, for example use of staticfree workstation and grounding strap. Only qualified personnel shall handle the product. Make it a habit always to first touch the mounting hole (which is grounded) for a few seconds with both hands before touching any other parts of the boards. That way, you will have the same potential as the board and therefore minimize the risk for ESD. In general touch as little as possible on the boards in order to minimize the risk of ESD damage. The only reasons to touch the board are when mounting/unmounting it on a carrier board. Note that Embedded Artists does not replace modules that have been damaged by ESD. 2.4 Product Compliance Visit Embedded Artists' website at http://www.embeddedartists.com/product_compliance for up to date information about product compliances such as CE, RoHS2, Conflict Minerals, REACH, etc. Copyright 2019 © Embedded Artists AB 1CX M.2 Module - Datasheet Page 6 3 Specification This chapter lists some of the more important characteristics of the M.2 module, but it is not a full specification of performance and timing. The main component in the design is Murata's 1CX module (full part number: LBEH5UL1CX), which in turn is based around Cypress CYW4356 chipset. For a full specification, see on Murata's 1CX Module (LBEH5UL1CX) see Murata’s 1CX product page (https://wireless.murata.com/eng/type-1cx.html) and the 1CX datasheet (url TBD).

Signals WL_REG_ON or BT_REG_ON must be held low for at least 700 microseconds after supply voltage has reached specification level before pulled high. 2 clock cycles of the 32.678kHz clock must also have passed before any of the signals is pulled high. These clock cycles will typically occur during the 700 microseconds but if the clock signal has a long delay during power-up, the 700 microsecond period can be extended. 3.2 External Sleep Clock The sleep clock signals can be applied to a powered and unpowered M.2 module. Clock Specification Frequency 32.768 kHz Frequency accuracy ±200 ppm Duty cycle 30 - 70% Clock jitter
