The radio frequency receives and dispatches the circuit NRF24L01





NRF24L01 can work in 2.4 GHz- 2.5 GHz ISM frequency band, function module such as this transceiver built-in frequency synthesizer, power amplifier, crystal oscillator, modulator, it is a sincere integrated level more high wireless transceiver. Outside of nRF24L01 circuit relatively simple, and merged enhanced ShockBurst technology, among them output power and communication channel can carry on the disposition through the procedure. Meanwhile, power consumption of chip this extremely low, when not launching with power of 6 dBm, working current its only 9 mA; While receiving, there is only 12.3 mA in the working current. The controlling circuit of nRF24L01 can link with mouth of SPI mouth and GPIO of STM32 control device. It is that the constituent radio frequency of this chip receive and dispatch the schematic circuit diagram that image shows.
