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-Amplifier I-Crystal amplifier imodyuli 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-12.3. mA kwimowudi yokwamkela, kwaye imowudi yokusetyenziswa yangoku isezantsi kwimowudi yokulinda.

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-MCU okanye ifaniswe yi-I / O port 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 sidingo sokucwangcisa ubhaqo lomthwali ubhaqo olusisigxina olwakhelwe ngaphakathi kwihardware yeCRC ubhaqo lwemposiso kunye nendawo-to-multipoint yonxibelelwano lwedilesi yolawulo lwemposiso yokuhanjiswa kwempazamo kunye nomsebenzi wobhaqo womthwali ungasetyenziselwa ukusetwa rhoqo kwe-hop inokusetwa ngaxeshanye ifumana iidilesi zetshaneli, inokukhetha ngokukhetha i-pin ye-standard ye-pin ye-Dip2.54MM ye-pitch interface, kulula ukuyifaka izicelo.
