Hardware Ukuhlanganiswa
I-MT0, i-chipset esekwe eNordic, izohlanganiswa ebhodini lomsingathi ngokuya ngokucaciswa okulandelayo kulo mhlahlandlela: https://infocenter.nordicsemi.com/pdf/nRF52840_PS_v1.7.pdf *sicela uvakashele ku-nordicsemi.com ukuze uthole okwamanje kakhulu imininingwane kanye nemiyalelo yokuhlanganisa.
Phina Izabelo
Idivayisi ye-nRF52840 ihlinzeka ngokuguquguquka ngokuphathelene nomzila wephinikhodi ye-GPIO nokumisa. Nokho, amanye amaphini anemikhawulo noma izincomo zokucushwa kwephinikhodi nokusetshenziswa.
Isitatimende sokuthobela i-FCC
Le divayisi ithobela ingxenye 15 yemithetho ye-FCC. Ukusebenza kungaphansi kwezimo ezimbili ezilandelayo: (1) Lolu cingo angeke lubangele ukuphazamiseka okuyingozi, futhi (2) lolu cingo kufanele lwamukele noma yikuphi ukuphazamiseka okutholiwe, okuhlanganisa ukuphazamiseka okungase kubangele ukusebenza okungafuneki.
Lesi sisetshenziswa sihloliwe futhi satholwa ukuthi sithobela imikhawulo yedivayisi yedijithali Yekilasi B, ngokuvumelana nengxenye 15 Yemithetho ye-FCC. Le mikhawulo iklanyelwe ukuhlinzeka ngokuvikeleka okufanele ekuphazanyisweni okuyingozi ekufakweni kwendawo yokuhlala. Lesi sixhobo sikhiqiza, sisebenzise futhi singakhipha amandla efrikhwensi yomsakazo futhi, uma ingafakiwe futhi isetshenziswe ngokuhambisana nemiyalelo, ingase ibangele ukuphazamiseka okuyingozi ezokuxhumana ngomsakazo. Nokho, asikho isiqinisekiso sokuthi ukuphazamiseka ngeke kwenzeke ekufakweni okuthile. Uma lesi sisetshenziswa sidala ukuphazamiseka okuyingozi emsakazweni noma kumabonakude, okunganqunywa ngokucisha nokuvula okokusebenza, umsebenzisi uyakhuthazwa ukuthi alungise ukuphazamiseka ngesinye salezi zinyathelo ezilandelayo:
- Hlela kabusha noma hambisa uthi olwamukelayo.
- Khulisa ukuhlukana phakathi kwesisetshenziswa nomamukeli.
- Xhuma okokusebenza endaweni yokuphuma kuyisekethe ehlukile lapho umamukeli axhumeke khona.
- Xhumana nomthengisi noma uchwepheshe werediyo/TV onesipiliyoni ukuze uthole usizo.
Isexwayiso se-FCC
Noma yiziphi izinguquko noma ukuguqulwa okungagunyazwanga ngokucacile ngu-Meraki kungase kuqede igunya lomsebenzisi lokusebenzisa lesi sisetshenziswa. Lesi Transmitter akufanele sibekwe endaweni eyodwa noma sisebenze ngokuhlangana nanoma iyiphi enye i-antenna noma isidluliseli.
Isitatimende Sokuchayeka Kwemisebe ye-FCC
Lokhu okokusebenza kuthobelana nemikhawulo yokuchayeka emisebeni ye-FCC ebekwe endaweni engalawuleki. Lo mshini kufanele ufakwe futhi usebenze ngebanga elincane elingama-20 cm phakathi kwe-radiator nomzimba wakho. Lesi sithumeli akumele sibekwe endaweni eyodwa noma sisebenze ngokuhlangana nanoma iyiphi enye i-antenna noma isidluliseli.
Isitatimende Semboni yaseCanada
Le divayisi ithobela i-RSS -247 Yemithetho Yemboni yaseCanada. Ukusebenza kungaphansi kwemibandela emibili elandelayo:
- Le divayisi ingase ingabangeli ukuphazamiseka okuyingozi, futhi
- Lolu cingo kufanele lwamukele noma yikuphi ukuphazamiseka okutholiwe, okuhlanganisa ukuphazamiseka okungase kubangele ukusebenza okungafuneki.
Isitatimende Sokuchayeka Kwemboni yaseCanada
Lesi sisetshenziswa sithobela imikhawulo yokuchayeka emisebeni ye-IC ebekwe endaweni engalawuleki. Lo mshini kufanele ufakwe futhi usebenze ngebanga elincane elingama-20 cm phakathi kwerediyetha nomzimba wakho.
