NRF24L01 ke chip e le 'ngoe ea transceiver e sebetsang sehlopheng sa 2.4-2.5GHz sa ISM sa bokahohle. Li-transceivers tse se nang mohala li kenyelletsa: Frequency generator Enhanced SchockBurstTM mode controller Power amplifier Crystal amplifier modulator Demodulator Output power channel khetho le protocol Litlhophiso li ka behoa ka SPI interface Tšebeliso e tlaase ea hona joale, Tšebeliso ea hona joale ke 9.0mA ha matla a phetisetso e le 6dBm ka mokhoa oa ho fetisa, 12mA mocheng oa ho amohela, o tlaase oa 3mA ka mokhoa oa ho amohela.

Bula sehlopha sa ISM, matla a maholo a phetisetso ea 0dBm, tšebeliso ea mahala ea laesense. E ts'ehetsa likanale tse tšeletseng tsa kamohelo ea data

1. Matla a tlaase a ho sebetsa: 1.9 ~ 3.6V Ts'ebetso ea motlakase e tlaase
2. Lebelo le phahameng: 2Mbps, ka lebaka la nako e khutšoanyane ea phetisetso ea moea, e fokotsa haholo ts'ebetso ea ho thulana ha phetisetso ea waelese (software set 1Mbps kapa 2Mbps air transmission rate)
3. Multi-frequency: 125 frequency points to meet the needs of multi-point communication and frequency-hopping communication
4. E nyane haholo: e hahelletsoeng ka har'a 2.4GHz antenna, boholo bo nyane, 15x29mm (ho kenyeletsoa le lenakana)
5. Tšebeliso e fokolang ea matla: Ha u sebetsa puisanong ea mokhoa oa ho arabela, phetisetso ea moea e potlakileng le nako ea ho qala e fokotsa haholo tšebeliso ea hona joale.
6. Litšenyehelo tse tlaase tsa kopo: NRF24L01 e kopanya likarolo tsohle tse potlakileng tsa ho sebetsana le lipontšo tse amanang le RF protocol, tse kang: ho khutlisetsoa ka mokhoa o itekanetseng oa lipakete tsa data tse lahlehileng le pontšo ea karabelo e ikemetseng, joalo-joalo Sebopeho sa SPI sa NRF24L01 se ka kopanngoa ke hardware SPI port ea MCU kapa e etsisoa ke I / O port ea MCU, 'me ho na le MCU ka hare.
7. Ho bonolo ho ntshetsa pele: Hobane lera la khokahanyo le kopantsoe ka ho feletseng mojuleng, ho bonolo haholo ho ntlafatsa. Ts'ebetso ea phetisetso ea othomathiki, ho lemoha ka boits'oaro le ho khutlisa lipakete tsa data tse lahlehileng, nako ea phetisetso le linako tsa phetisetso li ka laoloa ke software ho boloka ka bo eona pakete ea data ka mokhoa o ikhethileng o sa fumaneng pontšo ea karabo. Kamora ho fumana data e nepahetseng, mojule o tla romella lets'oao la karabo ka bo eona. Ha ho na tlhoko ea ho etsa lenaneo la ho sibolla motho ea nang le ts'ebetso e tsitsitseng ea "CRC" e kentsoeng ka har'a hardware ea ho lemoha phoso le point-to-multipoint address control packet transmission error counter le ts'ebetso ea carriers e ka sebelisoa bakeng sa litlhophiso tsa maqhubu a hop li ka behoa ka nako e ts'oanang le liaterese tse tšeletseng tse amohelang mocha, li ka bula ka mokhoa o ikhethileng mochine o amohelang pin Dip2.54MM pitch interface, e bonolo ho kenya lisebelisoa.
