R8002 Datasheet The device on-chip I2C logic provides the serial interface that meets the I2C bus standard mode specification. The I2C port handles byte transfers autonomously. The I2C H/W interfaces to the I2C bus via two pins: SDA and SCL. Pull up resistor is needed for I2C operation as these are open drain pins. When the I/O pins are used as I2C port, user must set the pins function to I2C in advance. 4.3.3 USB Device Controller USB2.0 fullspeed,4Eps, support host mode. 5. ELECTRICAL CHARACTERISTICS 5.

R8002 Datasheet 7. RECOMMENDED TEMPERATURE REFLOW PROFILE Prior to any reflow, it is important to ensure the modules were packaged to prevent moisture absorption. New packages contain desiccate (to absorb moisture) and a humidity indicator card to display the level maintained during storage and shipment. If directed to bake units on the card, please check the below next table and follow instructions specified by IPC/JEDEC J-STD-033. Note: The shipping tray cannot be heated above 65°C.
R8002 Datasheet Pre-heat zone (A) — This zone raises the temperature at a controlled rate, typically 0.5 – 2 °C/s. The purpose of this zone is to preheat the PCB board and components to 120 ~ 150 °C. This stage is required to distribute the heat uniformly to the PCB board and completely remove solvent to reduce the heat shock to components.

HARDWARE INTEGRATION SUGGESTIONS FSC-BT986 is compatible with industrial standard reflow profile for Pb-free solders. The reflow profile used is dependent on the thermal mass of the entire populated PCB, heat transfer efficiency of the oven and particular type of solder paste used. Consult the datasheet of particular solder paste for profile configurations.
R8002 Datasheet 9.2 Layout Guidelines(Internal Antenna) It is strongly recommended to use good layout practices to ensure proper operation of the module. Placing copper or any metal near antenna deteriorates its operation by having effect on the matching properties. Metal shield around the antenna will prevent the radiation and thus metal case should not be used with the module.
R8002 Datasheet As indicated in below, RF critical circuits of the module should be clearly separated from any digital circuits on the system board. All RF circuits in the module are close to the antenna port. The module, then, should be placed in this way that module digital part towards your digital section of the system PCB.

The distance of the micro strip line to the ground plane on the bottom side of the receiver is very small and has huge tolerances. Therefore, the impedance of this part of the trace cannot be controlled. Use as many vias as possible to connect the ground planes.
