MK02 Bluetooth Module Datasheet 5. Interfaces 5.1 Power Supply Regulated power for the MK02 is required. The input voltage VCC range should be 1.7V to 3.6V. Suitable decoupling must be provided by external decoupling circuitry (10uF and 0.1uF). It can reduce the noise from power supply and increase power stability. 5.2 System Function Interfaces 5.2.1 GPIO The general purpose I/O is organized as one port with up to 30 I/Os enabling access and control of up to 30 pins through one port.
MK02 Bluetooth Module Datasheet 5.2.3 Flash Program I/O The module has two programmer pins, respectively SWDCLK pin and SWDIO pin. The two pin Serial Wire Debug (SWD) interface provided as a part of the Debug Access Port (DAP) offers a flexible and powerful mechanism for non- intrusive debugging of program code. Breakpoints and single stepping are part of this support. 5.2.4 Serial Peripheral Interface The SPI interfaces enable full duplex synchronous communication between devices.

MK02 Bluetooth Module Datasheet 6. Mounting Suggestion You can refer to the following references for the mounting design of the module with on-board antenna (MK02D with PCB antenna). For external antenna modules (MK02E needs to connect an external antenna to the u.FL connector), you need to refer to the external antenna design requirements.
MK02 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.
MK02 Bluetooth Module Datasheet 7. Qualification and approvals 7.1 United States (FCC) The MK02 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.
MK02 Bluetooth Module Datasheet This module is approved for installation into mobile and/or portable host platforms and must not be 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. 7.
MK02 Bluetooth Module Datasheet 7.2.2 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.
MK02 Bluetooth Module Datasheet The MK02 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: 210-149849 7.5 Australia / New Zealand (RCM) The MK02 has been tested to comply with the AS/NZS 4268:2017, Radio equipment and systems Short range devices - Limits and methods of measurement.
MK02 Bluetooth Module Datasheet 8. Cautions 8.1 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.
MK02 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. 8.2 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).
MK02 Bluetooth Module Datasheet 8.3 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.
MK02 Bluetooth Module Datasheet Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01 2.1 Antennas The MK02 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.
