4 Applications
4.1 Application circuit
Active DC-DC Converter：
Figure 3: Application circuit: active DC-DC converter
Non-active DC-DC Converter:
Figure 4: Application circuit: non active DC-DC converter
Active DC-DC Converter will greatly reduce system power consumption, but will affect

sensitivity of the system. Using an internal LDO increases sensitivity, but system power
consumption will be slightly higher.
4.2 Precautions
To ensure the module's RF performance in the application of its maximum possible
effectiveness, the user should follow the following principles:
1. It is recommended to supply the module with DC power supply. The power supply ripple
coefficient should be as small as possible. The module should be reliably grounded. Please pay
attention to the correct connection of positive and negative poles of the power supply. If the
connection is reversed, the module may be damaged permanently.
2. Module recommendations placed on the edge of the floor open space, the antenna should be
outward;
3. The module under the antenna PCB (double-sided board and multi-layer board) need
clearance, can not be deposited copper, that is all the layout layer below the antenna can not
have grounding or signal trace;
4. It is better to keep metal parts away from the antenna, or module communication distance in
different environments will be shortened at different degrees. Please refer to recommended
locations in following figure:
Figure4: Module recommended placement
4.3 Download and Debug
The module supports the ARM serial wire debug (SWD) port, the SWD port pin is
DIO9(SWCLK),DIO10(SWDIO).Through J-link or ST-LINK, you can download and debug.
When the module is power up or hardware reset, if DIO7 is high, you can enter the boot mode,
the module is not available at this time, the module can be programmed through the serial port
code.

5 Federal Communications Commission (FCC) Interference Statement
This equipment has been tested and found to comply with the limits for a Class C
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.
Note: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
RF exposure warning
This equipment must be installed and operated in accordance with provided instructions
and the antenna(s) used for this transmitter must be installed to provide a separation
distance of at least 20 cm from all persons and must not be co-located or operating in
conjunction with any other antenna or transmitter. End-users and installers must be
provided with antenna installation instructions and transmitter operating conditions for
satisfying RF exposure compliance.
