QZBT628 PBC BLE Module
Product Information:
The QZBT628 is a Bluetooth Low Energy (BLE) module operating at
2.4GHz frequency band. It is fully compliant with Bluetooth 4.2
standards, allowing easy connectivity with Bluetooth Smart Ready
devices such as mobile phones, tablets, and laptops. The module
integrates a power-balanced 32-bit proprietary MCU, a
high-performance BLE/2.4GHz Radio, 16kB SRAM, a 512kB/128kB flash,
a general-purpose ADC, a quadrature decoder (QDEC), PWM, flexible
I/O interfaces, and other peripheral blocks required for Bluetooth
Low Energy application development.
Product Usage Instructions:
- Make sure the AVDD and DVDD V pins have the same voltage.
- Connect the module pins according to your customer needs. For
example, PB3 can be set as the Bluetooth external control pin (BTC)
to control the switch of other devices, and PA4 can be set as
P_SLEEP (low power control) to wake up the Bluetooth module. - Ensure that the supply voltage (VDD) is within the recommended
operating range of 1.9V to 3.6V. - When using the module in different modes, consider the
following DC characteristics:- TX mode: The current consumption ranges from 14.5mA to 25mA
depending on the transmission power. - RX mode: The current consumption is approximately 16mA.
- Suspend mode: The current consumption is approximately
8mA. - Deep sleep mode: The current consumption ranges from 10μA to
1.7μA depending on the wakeup source.
- TX mode: The current consumption ranges from 14.5mA to 25mA
- Connect the necessary external components according to the
schematic and BOM (Bill of Materials) provided in the user
manual. - Follow the PCB layout guidelines to ensure proper signal
integrity and performance. - Comply with FCC standards, specifically FCC CFR Title 47 Part
15 Subpart C Section 15.247. The module is equipped with a PCB
antenna with an antenna gain of -6.25dBi.
