7. Functional schematic
7.1 CPU
BC30 built-in ARM Cortex M4 32-bit microprocessor (MCU) with ultra low
16-bit RSIC for power consumption. The CPU clock speed is 80 MHz and can be up to 160 MHz.
Support for real-time operating system (RTOS). Currently, the Wi-Fi protocol stack uses only 20%
of MIPS, and others can be used for application programming and development. The CPU includes
the following interfaces:
◆ Configurable RAM/ROM (iBus) with on-chip memory controller and external Flash
◆ Data RAM interface (dBus) connected to the storage controller
◆ Access register AHB interface
7.2 Built-in storage
The BC30 chip has a built-in memory controller that includes ROM and SRAM. The MCU
can access the memory controller through the iBus, dBus, and AHB interfaces. All storage units
can be accessed after the request is initiated. The storage arbiter determines the order of access

based on when the processor accepts these requests. According to the SDK provided by our
company, when the BC30 is running in the Station mode and connected to the route, the available
SRAM space in the Heap+ Data area is 96kB. Embedded 8Mbit Flash storage.
7.3 External Flash
The BC30 uses an external SPI Flash to store the user program. In theory, it can support up to
16MB of storage.
8. Applications

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 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.
Changes or modifications not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
FCC Radiation Exposure Statement
This device complies with FCC RF radiation exposure limits set forth for an
uncontrolled environment. This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.
This device must operate with a minimum distance of 20 cm between the radiator and user body.
If the FCC identification number is not visible when the module is installed inside
another device, then the outside of the device into which the module is installed must
also display a label referring to the enclosed module. This exterior label can use
wording such as the following:
“Contains Transmitter Module FCC ID: 2AQSK-BC30”
When the module is installed inside another device, the user manual of this device
must contain below warning statements; 1. This device complies with Part 15 of the
FCC Rules. Operation is subject to the following two conditions: (1) This device may
not cause harmful interference. (2) This device must accept any interference received,
