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 kwesiteshi samandla okukhiphayo kanye nephrothokholi Izilungiselelo zingasethwa ngesixhumi esibonakalayo se-SPI Ukusetshenziswa okuphansi kwamanje, Ukusetshenziswa kwamanje kungu-9.0mA lapho amandla okudlulisela kungu-6dBm kumodi yokudlulisa, 123. mA kumodi yokwamukela, futhi imodi yokusebenzisa yamanje iphansi kwimodi yokulinda.

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 eziphansi zohlelo lokusebenza: I-NRF24L01 ihlanganisa zonke izingxenye zokucubungula isignali zesivinini esikhulu ezihlobene nephrothokholi ye-RF, njengokuthi: ukuthunyelwa kabusha okuzenzakalelayo kwamaphakethe edatha alahlekile kanye nesignali yokuphendula okuzenzakalelayo, njll. I-interface ye-SPI ye-NRF24L01 ingaxhunywa yi-hardware SPI port of i-MCU noma ifaniswe yichweba le-I/O le-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 ukutholwa kwe-frequency ye-hardware eyakhelwe ngaphakathi ye-CRC yokuthola iphutha kanye ne-point-to-multipoint ikheli lokulawula iphakethe lokudlulisa iphutha isibali kanye nomsebenzi wokuthola inkampani yenethiwekhi ingasetshenziselwa ukusetha i-frequency hop ingasethwa ngesikhathi esifanayo ithola amakheli esiteshi, ingavula ngokukhetha iphinikhodi evamile yokuthola i-Dip2.54MM, izinhlelo zokusebenza ezishumekiwe kalula.
