MK08 Bluetooth Module Datasheet 5. Mounting Suggestion You can refer to the following references for the mounting design of the module with on-board antenna (MK08A with PCB antenna). For external antenna modules (MK08B needs to connect an external antenna to the u.FL connector), you need to refer to the external antenna design requirements.
MK08 Bluetooth Module Datasheet Other module mounting examples: Placement of resin or plastic parts: 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.
MK08 Bluetooth Module Datasheet 6. Qualification and approvals 6.1 United States (FCC) The MK08 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.

MK08 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.
MK08 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).
MK08 Bluetooth Module Datasheet 7.3 Storage Notes • The module should not be stressed mechanically during storage. • Do not store these products in the following conditions or the performance characteristics of the product, such as RF performance will be adversely affected: o Storage in salty air or in an environment with a high concentration of corrosive gas. o Storage in direct sunlight o Storage in an environment where the temperature may be outside the range specified.
