Preliminary datasheet, Quintic Corporation reserves right to modify without notification2 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.

Preliminary datasheet, Quintic Corporation reserves right to modify without notification5 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. Figure 3 Layout for high performance
