MK14 Bluetooth Module Datasheet 5. Mounting Suggestion You can refer to the following references for the mounting design of the module with on-board antenna (MK14A with PCB antenna). For external antenna modules (MK14B needs to connect an external antenna to the u.FL connector), you need to refer to the external antenna design requirements. Recommended module mounting example: Placement of resin or plastic parts: 10 www.mokoblue.
MK14 Bluetooth Module Datasheet Placement of metal parts • Minimum safe distance for metal parts without seriously compromising the antenna (tuning) is 40 mm top/bottom and 30 mm left or right. • Metal close to the module antenna (bottom, top, left, right, any direction) will have degradation on the antenna performance. The amount of that degradation is entirely system dependent, meaning you will need to perform some testing with your host application.
MK14 Bluetooth Module Datasheet 6. Qualification and approvals 6.1 United States (FCC) The MK14 has received Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Subpart C “Intentional Radiators” modular approval in accordance with Part 15.247 Modular Transmitter approval.
MK14 Bluetooth Module Datasheet co-located or operating in conjunction with any other antenna or transmitter except in accordance with FCC multi-transmitter guidelines. End users must be provided with transmitter operating conditions for satisfying RF Exposure compliance. 6.2 Canada (ISED) The MK14 module is certified for use in Canada under Innovation, Science and Economic Development Canada (ISED) Radio Standards Specification (RSS) RSS-247 and RSSGen. 6.2.
MK14 Bluetooth Module Datasheet 6.2.2 RF exposure All transmitters regulated by IC must comply with RF exposure requirements listed in RSS-102 - Radio Frequency (RF) Exposure Compliance of Radiocommunication Apparatus (All Frequency Bands). This module is approved for installation into mobile and/or portable host platforms and must not be colocated or operating in conjunction with any other antenna or transmitter except in accordance with Industry Canada's multi-transmitter guidelines.
MK14 Bluetooth Module Datasheet The MK14 module is labeled with its assigned technical conformity mark and certification number. The end product in which this module is being used must have an external label referring to the type certified module inside: Contains transmitter module with certificate number: 217-204215 6.5 Australia / New Zealand (RCM) The MK14 has been tested to comply with the AS/NZS 4268:2017, Radio equipment and systems Short range devices - Limits and methods of measurement.
MK14 Bluetooth Module Datasheet 7. Cautions 7.1 Reflow Soldering Reflow soldering is a vitally important step in the SMT process. The temperature curve associated with the reflow is an essential parameter to control to ensure the correct connection of parts. The parameters of certain components will also directly impact the temperature curve selected for this step in the process.
MK14 Bluetooth Module Datasheet Example of MOKO SMT reflow soldering: Note: The module is LGA package. Please be careful of the amount of solder paste. The module may be lifted due to excess solder. 7.2 Usage Condition Notes • Follow the conditions written in this specification, especially the recommended condition ratings about the power supply applied to this product. • The supply voltage has to be free of AC ripple voltage (for example from a battery or a low noise regulator output).
MK14 Bluetooth Module Datasheet 7.3 Storage Notes • The module should not be stressed mechanically during storage.
MK14 Bluetooth Module Datasheet Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01 2.1 Antennas The MK14 is an BLE Module beams signals and communicates with its antenna, which is PCB Antenna and External 2.4Ghz antenna. Antenna could not be in no-load state when module is working. During debugging, it is suggested to add 50 ohms load to the antenna port to avoid damage or performance degradation of the module under longtime no-load condition.
MK14 Bluetooth Module Datasheet Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01 2.2 List of applicable FCC rules The MK14 is an BLE Module with digitally modulated systems using an GFSK modulation. It operates on the 2402- 2480MHz band.Complies with FCC CFR Title 47 Part 15 Subpart C Section 15.247. 2.
MK14 Bluetooth Module Datasheet 3) For all products market in US, OEM has to limit the Operating Frequency: 2402MHz - 2480MHz by supplied firmware programming tool. OEM shall not supply any tool or info to the end‐ user regarding to Regulatory Domain change. USERS MANUAL OF THE END PRODUCT: In the user manual of the end product, the end user has to be informed to keep at least 5mm separation with the antenna while this end product is installed and operated.
