The transmission distance of nrf24l0 1 is so short. What's the matter? Seek an answer

Nrf24l0 1 has no extra antenna gain, short transmission distance and is normal.

NRF24L0 1 is a new type of monolithic RF transceiver, which works in ISM band from 2.4 GHz to 2.5 GHz.

Built-in frequency synthesizer, power amplifier, crystal oscillator, modulator and other functional modules, and integrated enhanced ShockBurst technology, in which the output power and communication channel can be configured through programs.

The power consumption of nRF24L0 1 is low, and the working current is only 9mA when transmitting at -6dBm power. When receiving, the working current is only 12.3mA, and when working at 100mw, the current is 160mA.

Extended data:

NRF24L0 1 requires high voltage and stable power supply voltage, so the power supply has been stabilized twice. The ideal working voltage of nRF24L0 1 wireless module is 3.3 volts, and the primary voltage regulator needs to convert the voltage to meet the working voltage of wireless module.

The power supply voltage of this module is 7.5v, which is converted into a stable voltage of 5v by LM7805 voltage stabilizing module, and converted into 3.3v required by wireless module by AMS117 voltage stabilizing module.
