I-Raspberry PI POE+ HAT

Uxhumo lwezingxenyekazi zekhompuyutha:
Ngaphambi kokufaka i-PoE+ HAT, faka izigxobo zethusi ezihlinzekiwe emakhoneni amane ebhodi lesekethe. Ngemva kokuxhuma i-PoE+HAT kuzimbobo ze-40Pin kanye ne-4-pin PoE ye-Raspberry PI, i-PoE+HAT ingaxhunywa kudivayisi ye-PoE ngentambo yenethiwekhi ukuze kutholakale amandla kanye nokuxhumana kwenethiwekhi. Lapho ukhipha i-PoE+HAT, donsa i-POE + Hat ngokulinganayo ukuze ukhulule imojuli ngokushelela ephinikhodi ye-Raspberry PI futhi ugweme ukugoba iphini.

Incazelo yesofthiwe:
I-PoE+ HAT ifakwe isiphephetha-moya esincane, esilawulwa yi-Raspberry PI nge-I2C. Ifeni izovula futhi ivale ngokuzenzakalelayo ngokuya ngezinga lokushisa lephrosesa eyinhloko ku-Raspberry PI. Ukuze usebenzise lo mkhiqizo, qinisekisa ukuthi isofthiwe ye-Raspberry PI iyinguqulo entsha

Qaphela:
● Lo mkhiqizo ungaxhunywa kuphela ku-Raspberry Pi ngezikhonkwane ezine ze-PoE.
Noma imaphi amadivaysi angaphandle anikezela ngogesi/izijovo zikagesi ezisetshenziselwa ukunika amandla i-Ethernet azothobelana nemithethonqubo esebenzayo namazinga ezweni elihlosiwe.
● Lo mkhiqizo kufanele usebenze endaweni enomoya omuhle, uma usetshenziswa ku-chassis, i-chassis akufanele imbozwe.
Uxhumano lwe-GPIO oluxhuma idivayisi engasebenzisani nekhompyutha ye-Raspberry Pi lungase luthinte ukuthobelana futhi ludale umonakalo kudivayisi futhi luvale iwaranti.
Zonke izinto ezisetshenziswa kulo mkhiqizo zizothobela izindinganiso ezifanele zezwe lokusetshenziswa futhi zimakwe ngokufanele ukuze kuqinisekiswe ukuthi izidingo zokuphepha nokusebenza ziyahlangatshezwa.
Lezi zihloko zifaka, kodwa azikhawulelwe, kukhibhodi, ukuqapha, kanye negundane uma kusetshenziswa ngokuhambisana nekhompyutha ye-Raspberry Pi.
Uma ama-peripheral axhunyiwe engabandakanyi ikhebula noma isixhumi, ikhebula noma isixhumi kufanele sinikeze ukufakwa okwanele nokusebenza ukuze kuhlangatshezwane nezidingo ezifanele zokusebenza nezokuphepha.
Ulwazi lokuphepha
Ukuze ugweme ukwehluleka noma ukulimala kwalo mkhiqizo, sicela uqaphele okulandelayo:
● Ungawathinti amanzi noma umswakama ngesikhathi usebenza, noma beka endaweni esebenza kahle.
● Ungachayeka ekushiseni kunoma yimuphi umthombo. Ikhompyutha ye-Raspberry Pi kanye ne-Raspberry Pi PoE+ HAT yakhelwe ukuthi isebenze ngendlela enokwethenjelwa ekushiseni okujwayelekile kwegumbi.
● Qaphela lapho uphatha ukugwema ukulimala ngomshini noma kagesi ebhodini lesekethe eliphrintiwe nezixhumi.
● Gwema ukuthatha ibhodi lesekethe eliphrintiwe uma livuliwe, futhi ubambe kuphela imiphetho ukuze unciphise ubungozi bokulimala kokukhishwa kwe-electrostatic.
