MK11A Bluetooth Module Datasheet 5. Mounting Suggestion You can refer to the following references for the mounting design of MK11A. Recommended module mounting example: • Please do not place any metal components in blue shaded space (*1), such as signal line and metal chassis as possible except for main board while mounting the components in *1 space on the main board is allowed except for no copper plating area (*2). • (*2) This area is routing prohibited area on the main board.
MK11A 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.
MK11A Bluetooth Module Datasheet 6. Cautions 6.1 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.
MK11A 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. 6.2 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).
MK11A Bluetooth Module Datasheet 6.3 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.
MK11A Bluetooth Module Datasheet Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01 2.1 Antennas The MK11A is an BLE Module beams signals and communicates with its antenna, which is PCB 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 long-time no-load condition.
MK11A Bluetooth Module Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01 Datasheet 2.2 List of applicable FCC rules The Bluetooth Low Energy Module 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.
MK11A Bluetooth Module Datasheet 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. The end user has to be informed that the FCC radio‐ frequency exposure guidelines for an uncontrolled environment can be satisfied. The end user has to also be informed that any changes or modifications not expressly approved by the manufacturer could void the user's authority to operate this equipment.
