Imodyuli encinci ye-NRF24L01+ engenangcingo Imodyuli yamandla ephuculweyo ye-2.4G ye-transceiver engenazingcingo

Ulwazi lwemveliso

Ingcaciso yeMveliso
Ukubonelela ngezicwangciso, inkqubo ye-PID
I-NRF24L01 yi-chip eyodwa ye-transceiver chip esebenza kwi-2.4-2.5GHz band ye-ISM jikelele. Ii-transceivers ezingenazingcingo zibandakanya: I-Frequency generator I-SchockBurst TM isilawuli semowudi ephuculweyo ye-SchockBurst TM Isilawuli semowudi ye-SchockBurst TM yamandla amplifier Imodyuli ye-Crystal amplifier I-Demodulator Isiphumo sokukhetha umjelo wamandla kunye neprotocol Izicwangciso zingasetwa nge-SPI interface Ukusetyenziswa okuphantsi kwangoku, Ukusetyenziswa kwangoku yi-9.0mA xa amandla okuhambisa i-6dBm kwimodi yokuhambisa, i-mode yokusetyenziswa kwe-12 yi-3mA yangoku kunye ne-3mA yangoku.

Vula ibhendi ye-ISM, amandla amakhulu okuhanjiswa kwe-0dBm, ukusetyenziswa kwelayisensi simahla. Ixhasa amajelo amathandathu okufumana idatha

1. Umbane ophantsi osebenzayo: 1.9 ~ 3.6V Ukusebenza kwamandla ombane ophantsi
2. Isantya esiphezulu: I-2Mbps, ngenxa yexesha elifutshane lokuhambisa umoya, linciphisa kakhulu isiganeko sokungqubuzana kwi-wireless transmission (iseti yesofthiwe ye-1Mbps okanye i-2Mbps izinga lokuhambisa umoya)
3. I-multi-frequency: Amanqaku angama-125 ukuhlangabezana neemfuno zonxibelelwano lwamanqaku amaninzi kunye nonxibelelwano lwe-frequency-hopping
4. I-eriyali eyakhelwe-ngaphakathi eyi-2.4GHz, ubungakanani obuncinci, 15x29mm (kubandakanya i-eriyali)
5. Ukusetyenziswa kwamandla aphantsi: Xa usebenza kwimodi yokuphendula unxibelelwano, ukuhanjiswa komoya ngokukhawuleza kunye nexesha lokuqalisa kunciphisa kakhulu ukusetyenziswa kwangoku.
6. Ixabiso eliphantsi lesicelo: I-NRF24L01 idibanisa zonke iinxalenye ze-speed-speed processing signal ezinxulumene ne-RF protocol, ezifana: ukuhanjiswa ngokuzenzekelayo kweepakethi zedatha ezilahlekileyo kunye nomqondiso wokuphendula ngokuzenzekelayo, njl njl. I-SPI interface ye-NRF24L01 inokudibaniswa ne-hardware SPI port ye-MCU okanye ifaniswe yi-port ye-I / O ye-MCU, kwaye kukho i-MCU ngaphakathi.
7. Kulula ukuphuhlisa: Ngenxa yokuba umgca wekhonkco uhlanganiswe ngokupheleleyo kwimodyuli, kulula kakhulu ukuphuhlisa. Umsebenzi wokubuyisela ngokuzenzekelayo, ukufumanisa ngokuzenzekelayo kunye nokuhanjiswa kweepakethi zedatha ezilahlekileyo, ixesha lokubuyisela kwakhona kunye namaxesha okubuyisela kwakhona kunokulawulwa yi-software ukugcina ngokuzenzekelayo ipakethi yedatha umsebenzi wokuphendula ngokuzenzekelayo ongafumani umqondiso wokuphendula. Emva kokufumana idatha esebenzayo, imodyuli ithumela ngokuzenzekelayo uphawu lokuphendula. Akukho mfuneko yokucwangcisa ubhaqo womthwali ubhaqo olusisigxina lwe-hardware eyakhelwe-ngaphakathi kwi-hardware ye-CRC ubhaqo lwempazamo kunye ne-point-to-multipoint yonxibelelwano lwedilesi yokulawula ipakethe yempazamo yokuhambisa i-counter kunye nomsebenzi wokubona umthwali ungasetyenziselwa ukusetwa kwamaxesha ama-hop anokusetwa ngexesha elinye iidilesi zetshaneli ezithandathu zokufumana, zinokuvula ngokukhethayo itshaneli yokufumana iphini eliqhelekileyo le-Dip2.54MM pitch interface, kulula ukuyifaka izicelo ezizinzisiweyo.
