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；

4.2 Software programming

Insert the module on the user's circuit board, use the microcontroller to communicate with it through SPI or serial

port, and operate its control register and transmit / receive buffer through the SPI instruction. Please refer to the
latest nRF24L01P datasheet for the register read and write operations.
IRQ is an interrupt pin. It is used to wake up the microcontroller and achieve fast response; users can leave it

unconnected and use SPI to query the interrupt status (not recommended, not conducive to overall power
consumption, low efficiency)
CE can be connected to high level for a long time, but the module must be set to POWER DOWN power-down

mode when writing to the register. It is recommended that CE be controlled by MCU pin.
