2 Description
2.1 Model Definition
Explain: 1. QS9321-PLCM, without shielding box, FCC ID: 2AB359321-1.
2. QS9321-PLCS, with shielding box, the circuit design is the same as QS9321-PLCM,
FCC ID: 2AB359321-0.
2.2 Module description
QS9321 is a compact, surface mount Bluetooth 4.0 Low Energy (BLE) compliant wireless module. It
integrates an advanced single-chip BLE SoC chip – QN9021 with RF circuit and PCB antenna in a compact
module. Embedded 16 MHz and 32.678 kHz crystals are used for clock generation. Impedance matching
provides optimal radio performance with extremely low spurious emissions. QS9321 can be used directly
with a 3V coin cell battery or 3V DC power supply.
Small size gives good radiation efficiency with low price even when the module is used in layouts with
very limited space and easy modular handling.
QS9321 offers all Bluetooth low energy features: radio, stack, profiles and application space for
customer applications, so no external processor is needed. QS9321 can also be used to transfer raw data
between each other through the factory built-in application.
The pre-qualified module enables users to add Bluetooth Low Energy to traditional products within the
shortest time. QS9321 is leading the way for the new generation of Bluetooth low energy modules.

5 Layout and Physical Dimensions
5.1 Physical dimensions
Figure 2
Physical dimensions and pinout (mm)
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. Use good layout practices to avoid any excessive noise coupling to signal lines or supply
voltage lines.
Place nothing around the antenna for the high antenna performance as shown in Figure 3. If can’t
layout as aforesaid, avoid placing GND plane closer than 5 mm as shown in Figure 4 and any other dielectric
material closer than 1 mm from the antenna as shown in Figure 5. Anything closer than this distance from
the antenna will detune the antenna to lower frequencies and reduce the RF power.

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. Thus following recommendation should be taken as a starting point guide.
- Refer to technical documentations of particular solder paste for profile configurations
- Avoid using more than one flow.
- Aperture size of the stencil should be 1:1 with the pad size.

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 3 V 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.
