System Block Diagram  DNSA141 is based on QCA4002 Internet of Everything chip and QCA’s SP141 reference board design in stamp form factor.  Inside the module, there is a QCA4002 main chip which control the WLAN RF and BB function, also embedded a small processor which can do the encryption and TCP/IP off load. Only few external components are necessary such as XTAL and Flash. Block Diagram as Fig. 1:  Flash is only storing the binary code to control the QCA4002. RF calibration data is stored inside QCA4002 OTP not this flash. QCA also move the common data such as target power and CTL table to driver level called “Board Data File”. This can reduce the OTP size usage.  For complex control or more GPIO demanding, customer has to use a Micro Processor to control this module through SPI interface. QCA4004 will be in SPI slave mode.  USB interface is only for engineering RD mode such as production testing purpose or reprogram the external flash memory.

The spurious emission, unique antenna connector and photo of antennas are shown in the test report. 5. “The modular transmitter must be tested in a stand-alone configuration” The EUT was tested in a stand-alone configuration via a USB extender. Please see section Photographs of Test Configuration in the test report, the EUT was plugged in this extender. 6. “The modular transmitter must be labeled with its own FCC ID number.” Please see exhibition Label Sample for the FCC ID of this module. And also in the exhibition Users Manual, there are instructions give to the OEM on how to label the end product. 7. “The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements.” The EUT is compliant with all applicable FCC rules. Detail instructions for maintaining compliance are given in the Users Manual. 8. “The modular transmitter must comply with any applicable RF exposure requirements.” The EUT is compliant with all applicable RF exposure requirements. RF Exposure is addressed in the RF exposure exhibition. Please contact me if you have any further questions. Thanks for your attention. Best Regards, Hank Chung Assistant Manager Bureau Veritas Consumer Products Services (H.K.) Ltd., Hsinchu Branch
