Imojula encane ye-NRF24L01+ engenantambo Amandla athuthukisiwe we-2.4G ye-transceiver module

Ulwazi lomkhiqizo

Incazelo yomkhiqizo
Nikeza ama-schematics, uhlelo lwe-PID
I-NRF24L01 iyi-chip ye-transceiver chip eyodwa esebenza kubhendi yomhlaba wonke ye-ISM engu-2.4-2.5GHz. Ama-transceivers angenantambo ahlanganisa: I-Frequency generator Isilawuli semodi ye-SchockBurstTM ethuthukisiwe I-amplifier yamandla I-Crystal amplifier modulator I-Demodulator Ukukhethwa kweshaneli yamandla okukhiphayo kanye nephrothokholi Izilungiselelo zingasethwa ngesixhumi esibonakalayo se-SPI Ukusetshenziswa okuphansi kwamanje, Ukusetshenziswa kwamanje kungu-9.0mA lapho amandla okudlulisela kuyi-6dBm kumodi yokudlulisa, imodi yokusetshenziswa kwe-12.3mA ephansi futhi imodi yokwamukela i-3m yamanje.

Vula ibhendi ye-ISM, amandla amakhulu okudlulisa angu-0dBm, ukusetshenziswa kwamahhala kwelayisensi. Isekela iziteshi eziyisithupha zokwamukela idatha

1. I-voltage ephansi yokusebenza: 1.9 ~ 3.6V Ukusebenza kwe-voltage ephansi
2. Isivinini esikhulu: 2Mbps, ngenxa yesikhathi esifushane sokudlulisa komoya, sinciphisa kakhulu isenzakalo sokungqubuzana ekudluliselweni okungenantambo (isethi yesofthiwe engu-1Mbps noma i-2Mbps izinga lokudlulisa umoya)
3. Multi-frequency: 125 frequency points ukuhlangabezana nezidingo zokuxhumana ngamaphuzu amaningi kanye nokuxhumana kwe-frequency-hopping
4. Okuncane kakhulu: i-antenna eyakhelwe ngaphakathi engu-2.4GHz, usayizi omncane, 15x29mm (kufaka phakathi i-antenna)
5. Ukusetshenziswa kwamandla okuphansi: Uma usebenza ekukhulumisaneni kwemodi yokuphendula, ukuhanjiswa komoya okusheshayo nesikhathi sokuqalisa kunciphisa kakhulu ukusetshenziswa kwamanje.
6. Izindleko zokufaka isicelo eziphansi: I-NRF24L01 ihlanganisa zonke izingxenye zokucubungula isignali yesivinini esikhulu ezihlobene nephrothokholi ye-RF, njengokuthi: ukuthunyelwa kabusha okuzenzakalelayo kwamaphakethe wedatha elahlekile kanye nesignali yokuphendula okuzenzakalelayo, njll. I-interface ye-SPI ye-NRF24L01 ingaxhunywa nge-hardware SPI port ye-MCU noma ifaniswe yi-port ye-I/O ye-MCU, futhi kukhona i-MCU ngaphakathi.
7. Kulula ukuthuthukisa: Ngenxa yokuthi ungqimba lwesixhumanisi luhlanganiswe ngokugcwele kumojula, kulula kakhulu ukuthuthukisa. Umsebenzi wokudlulisela kabusha okuzenzakalelayo, ukutholwa okuzenzakalelayo kanye nokudluliselwa kabusha kwamaphakethe edatha alahlekile, isikhathi sokudlulisela kabusha kanye nezikhathi zokudlulisela kabusha kungalawulwa isofthiwe ukuze igcine ngokuzenzakalelayo umsebenzi wokuphendula ozenzakalelayo wephakethe ledatha ongawutholi isignali yokuphendula. Ngemva kokuthola idatha evumelekile, imojula ithumela ngokuzenzakalelayo isignali yokuphendula. Asikho isidingo sokuhlela ukutholwa kwenkampani yenethiwekhi ukuthola imvamisa egxilile yokutholwa kwezingxenyekazi zekhompuyutha ezakhelwe ngaphakathi ze-CRC kanye ne-point-to-multipoint ukuxhumana kwekheli lokulawula ipakethe yesibali kanye nomsebenzi wokuthola inkampani yenethiwekhi ingasetshenziselwa ukusetha i-frequency hop ingasethwa ngesikhathi esifanayo amakheli esiteshi ayisithupha, ingavula ngokukhetha otholayo isixhumi esibonakalayo sephimbo esijwayelekile sesiteshi se-Dip2.54MM, kulula ukushumeka izinhlelo zokusebenza.
