4. Basic operation
4. 1 Hardware design
It is recommended to use a DC stabilized power supply. The power supply ripple factor is as small as possible, and
the module needs to be reliably grounded；
Please pay attention to the correct connection of the positive and negative poles of the power supply. Reverse
connection may cause permanent damage to the module；
Please check the power supply to ensure it is within the recommended voltage otherwise when it exceeds the
maximum value the module will be permanently damaged;
Please check the stability of the power supply, the voltage can not be fluctuated frequently；
When designing the power supply circuit for the module, it is often recommended to reserve more than 30 % of the
margin, so the whole machine is beneficial for long- term stable operation;
The module should be as far away as possible from the power supply, transformers, high-frequency wiring and other
parts with large electromagnetic interference;
High-frequency digital routing, high-frequency analog routing, and power routing must be avoided under the
module. If it is necessary to pass through the module, assume that the module is soldered to the Top Layer, and the
copper is spread on the Top Layer of the module contact part( well grounded) , it must be close to the digital part of
the module and routed in the Bottom Layer；
Assuming the module is soldered or placed over the Top Layer, it is wrong to randomly route over the Bottom Layer
or other layers, which will affect the module's spurs and receiving sensitivity to varying degrees；
It is assumed that there are devices with large electromagnetic interference around the module that will greatly
affect the performance. It is recommended to keep them away from the module according to the strength of the
interference. If necessary, appropriate isolation and shielding can be done；
Assume that there are traces with large electromagnetic interference ( high- frequency digital, high- frequency analog,
power traces) around the module that will greatly affect the performance of the module. It is recommended to stay
away from the module according to the strength of the interference. If necessary, appropriate isolation and shielding
can be done.
If the communication line uses a 5V level, a 1k-5. 1k resistor must be connected in series (not recommended, there is
still a risk of damage)；
Try to stay away from some physical layers such as TTL protocol at 2.4GHz , for example: USB3.0 ；
The mounting structure of antenna has a great influence on the performance of the module. It is necessary to ensure
that the antenna is exposed, preferably vertically upward. When the module is mounted inside the case, use a good
antenna extension cable to extend the antenna to the outside；
The antenna must not be installed inside the metal case, which will cause the transmission distance to be greatly
weakened.
Conductors or other sources of interference should be avoided around the onboard PCB antenna.
4.2 Software editing
Insert the module into the user circuit board, use the microcontroller to communicate with the module by SPI or

serial port, and operate the control register and the transceiver buffer through the SPI command to complete the
wireless data transmit and receive function. For the timing operation of the module register read and write
operations, please refer to the latest nRF24L01 P data sheet.
As interrupt pin for IRQ, it can be used to wake-up MCU and achieve fast response; But the user can get the
interrupt status through SPI ( not recommended, it is not conducive to the overall power consumption, and with low
efficiency)；
CE pin can be high level for long-term, but it needs to set as POWER DOWN mode when the module writes
registers, and it is recommended that CE is controlled by MCU pin；

6.FAQ
6. 1 Communication range is too short
The communication distance will be affected when obstacle exists.
Data lose rate will be affected by temperature, humidity and co-channel interference.
The ground will absorb and reflect wireless radio wave, so the performance will be poor when testing near ground.
Sea water has great ability in absorbing wireless radio wave, so performance will be poor when testing near the sea.
The signal will be affected when the antenna is near metal object or put in a metal case.
Power register was set incorrectly, air data rate is set as too high ( the higher the air data rate, the shorter the
distance).
The power supply low voltage under room temperature is lower than 2 . 5 V, the lower the voltage, the lower the
transmitting power.
Due to antenna quality or poor matching between antenna and module.

6.2 Module is easy to damage
Please check the power supply source, ensure it is 2.0V~3.6 V, voltage higher than 3.6V will damage the module.
Please check the stability of power source, the voltage cannot fluctuate too much.
Please make sure antistatic measure are taken when installing and using, high frequency devices have electrostatic
susceptibility.
Please ensure the humidity is within limited range, some parts are sensitive to humidity.
Please avoid using modules under too high or too low temperature.
6.3 BER(Bit Error Rate) is high
There are co- channel signal interference nearby, please be away from interference sources or modify frequency and
channel to avoid interference;
Poor power supply may cause messy code. Make sure that the power supply is reliable.
The extension line and feeder quality are poor or too long, so the bit error rate is high;
