OEM Installation Guide
Installation Notes
• Multi-surface pads provide both bottom pads for high volume reflow soldering and edge pads for low
volume hand soldering.
• Power supply to module should have less than 10mVrms noise between 0-10MHz, and spikes should be
minimal.
• Regulator should have a fast response time < 20µs. It is essential that the power rail recover quickly.
• 10µF or larger capacitor filter for VDD input.
• All unused pins should be unconnected.
• The area around the module should be free of any ground planes, power planes, trace routings, or
metal. Minimum clearance is 5mm, but additional clearance allows improved range and throughput.
• Recommend connections for all four UART pins (DB-9 connector or test points) for firmware updates.
• Recommend test points for all four SPI pins, for emergency factory debugging and firmware reloading.
• Do not clean modules with Alcohol which can interact with no-clean solder flux residue.
• Do not use ultra sonic cleaning, which may cause internal interconnect damage.
• Do not modify any hardware components on the module without prior written consent.
• Do not modify any firmware without prior written consent.
• Final products that contain a KC Wirefree Bluetooth Module device must display
a visble label referring to the enclosed module similar to the following label:
