BK7231M_QFN32 Bluetooth dual-mode 5.1 and Wi-Fi 802.11n
The chip.Integrated with the hardware and software resources needed for
complete Wi-Fi and Bluetooth applications, it can support dual role
connectivity of AP and STA, and Both classic Bluetooth and Bluetooth low power
connections are supported.Up to 120 MHz of 32-bit MCU and 256 KB of built-in
RAM,
Can make the chip support multi-cloud connection.
The C-8031U has a wealth of peripherals, such as PWM, I2C, UART, SPI, SDIO,
and IrDA.You can directly use UART
Load and burn program.Up to six channels of 32-bit high speed PWM output using
the chip are ideal for high quality LED control.Every 2 PWM can
Configured for phase controlled differential mode to support motor and strip
drives.
The C-8031U integrates a prioritized Wi-Fi and Bluetooth control module to
implement real-time priority and send/receive scheduling.C-8031U
External PA and LNA extensions can be supported by providing an indication of
the status of the current transceiver.
The C-8031U is embedded with eFUSE and supports OTP read and write in FLASH.

1.1 List of applicable FCC rules:
The module complies with FCC Part 15.247.
1.2 Summarize the specific operational use conditions:
The module has been certified for Fix, Mobile, Portable applications.
This transmitter must not be co‐located or operating in conjunction with any
other antenna or transmitter.
1.3 Limited module procedures:
The module has its own RF shielding, which belong to signal module Standard
requires:
Clear and specific instructions describing the conditions, limitations and
procedures for third‐parties to use and/or integrate the module into a host
device (see Comprehensive integration instructions below).
Resolve: Supply example as follows:
Installation Notes:
- C-8031U Module Power supply range is DC 3.3V~3.6 V, when you use C-8031U Module design product, the power supply cannot exceed this range.
- When connect C-8031U Module to the host device, the host device must be power off.
- Make sure the module pins correctly installed.
- Make sure that the module does not allow users to replace or demolition.
1.4 Trace antenna designs:
Not applicable.
1.5 RF exposure considerations:
This equipment complies with FCC RF radiation exposure limits set forth for an
uncontrolled environment. The antenna(s) used for this transmitter must not be
collocated or operating in conjunction with any other antenna or transmitter.
Note: the host product manuals must include a statement in order to alert
the users of FCC RF exposure compliance.
1.6 Antennas
PCB antenna, 1dBi
The antenna is permanently attached, can’t be replaced.
1.7 Label and compliance information
This device complies with part 15 of the FCC rules. Operation is subject to
the following two conditions:
- this device may not cause harmful interference, and
- this device must accept any interference received, including interference that may cause undesired operation.
Warning: Changes or modifications to this unit not expressly approved by
the party responsible for compliance could void the user’s authority to
operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates uses and
can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
