5 Layout and Physical Dimensions 5.1 Physical dimensions Figure 2 Physical dimensions and pinout (mm) – Bottom view 5.2 Layout guide For optimal performance of the antenna place the module at the position of the PCB as shown in the following figures. Do not place any metal (traces, components, battery etc.) within the clearance area of the antenna. Connect all the GND pins directly to a solid GND plane. Place the GND vias as close to the GND pins as possible.

6 Soldering Recommendations QS9321 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.. Since the profile used is process and layout dependent, the optimum profile should be studied case by case.
7 Application Reference QS9321 integrates BLE SoC chip – QN9021 with RF circuit and PCB antenna in a compact module. It can be used directly with a 3V coin cell battery or 3V DC regulated power supply When QS9321 is used as a MCU with BLE feature, program flow can refer to the QN9021’s user manual. When QS9321 is used as only a RF module for transfer raw data though BLE 4.0 wireless system by the built-in application, the reference circuit schematic and programming guide see the following section. 7.
