Usuku lwa izolo bengikhuluma ngekithi into yayo eyinhloko i-Raspberry pi, egxile emakethe yezingane ezinentshisekelo yokwakha ikhompyutha yazo.
Hhayi, ngaphezulu kwesonto eledlule, abasebenzisi abaningi be-Raspberry Pi abathenga i-plugin ye-PoE HAT baqala ukwenza izimangalo eziningi ezinkundleni ezahlukahlukene ngisho naphakathi kwebhulogi le-Raspberry.
Ngoba abasebenzisi abaningi kubikwe izingqinamba nge-Raspberry Pi Power-over-Ethernet HAT esanda kukhishwa, iRaspberry Pi Foundation inikela ukubuyisela imali kumakhasimende athenge ibhodi elingalungile.
Ezinsukwini ngemuva kokukhishwa kwayo ngasekupheleni kuka-Agasti, abasebenzisi bebelokhu bebika ukulinganiselwa emandleni ahanjisiwe by Raspberry Pi PoE HAT.
I-HAT ingumphelelisi weRaspberry Pi 3 Model B + SBC ethandwayo enamandla kagesi wokushintshana ahlukaniswe ngokuphelele ane-37-57V DC, okokufaka kweClass 2 kanye nokukhishwa kwe-5V / 2.5A DC.
La I-HAT ixhuma kusixhumi se-pin-40 kanye neheda entsha ye-PoE ekhethekile ye-4-pin eyethulwe nge-B +, etholakala eduze namachweba e-USB.
El I-PoE HAT inikezwa nge-fan engu-25 x 25mm engashayeki ukupholisa i-Broadcom SoC.
Kepha ngeshwa, le nsiza ayikwazanga ukwamukelwa kahle yimakethe ngenxa yenkinga eshiwo ngenhla.
Emasontweni angenele, onjiniyela eRaspberry Raspberry Pi Foundation bebelokhu bephithizela ukuthola uhlobo lwenkinga. Ukunyakaza okuthakazelisayo kungalandelwa ezinkundleni ze-Raspberry Pi.
Mayelana nenkinga
Esihlokweni kuRejista , inkinga yachazwa ngu-Eben Upton, umsunguli wesisekelo kanye ne-CEO yeRaspberry Pi Trading.
Ngokusho kuka-Upton:
"Lokhu ukuxhumana phakathi kwesilawuli sokushintsha imvamisa esezingeni eliphansi ku-HAT kanye nolunye lwemikhiqizo emibili yeswishi yokukhawulela i-USB esiyisebenzisa ebhodini elikhulu."
Upton ichaze lokho ngoba isilawuli sisebenza ngokulingana kaningi, ngaso sonke isikhathi uma uyiguqula, uhambisa inani elikhulu lamandla kuzinqolobane ezintathu zokugcina i-USB ngokusebenzisa inkinobho yamanje enomkhawulo.
Lo mzuzu omkhulu osheshayo ukhohlisa iswishi ukuthi icabange ukuthi umcimbi weqiniso owedlulele uyenzeka.
“Sikulahlekele ekuhlolweni komkhiqizo ngoba (inhlanhla eyisimungulu) ukuhlola kwethu umthwalo osindayo kwenziwa emabhodini ngolunye uhlobo lwama-switch, futhi iningi labahloli bethu bezinkundla basebenzise kuphela ibhodi ukunika amandla amagundane namakhibhodi, okusebenza kahle. kuwo wonke ama-HAT / Pi pair esiwahlolile, ”kusho u-Upton.
Amaphuzu Ayisihluthulelo We-Raspberry Pi PoE HAT Izinkinga, futhi nezinyathelo ezithathiwe zacaciswa encwadini u-Upton ayithumela kwiRejista, futhi zabhalwa nasezithangamini ze-Raspberry Pi.
Yilezi ezilandelayo:
- “Ingxenye enkulu yamabhangqa we-HAT / Pi anqunyelwe ukuletha ngaphansi kwama-200 mA wamanzi asezansi nomfula ku-USB. Lokhu ngokuvamile kwanele amagundane namakhibhodi, kepha hhayi amadrayivu anzima, isibonelo «.
- "Sizokulungisa lokhu ngokuhamba kwesikhathi ku-PoE HAT."
- Okwamanje, sizongeza inothi lapho i-HAT ithengiswa khona, sibhala lo mkhawulo.
- “Sizohlinzeka ngezindlela ezimbalwa zemodi ezisebenzisekayo kubasebenzisi abazithandayo. Kungenzeka babe:
- "Ukususa izigqoko zamathangi ebhodini elikhulu (indlela elula nehlanzekile uma ungasebenzisa i-soldering iron, kodwa inciphisa ukuxhumana kwe-USB)."
- "Faka inani elincane le-impedance yochungechunge endleleni yamanje esuka ku-HAT (lokhu kuzoba nzima ukukusebenzisa)."
- Amaphuzu ayisihluthulelo wezinkinga ze-Raspberry Pi PoE HAT, nezinyathelo ezithathiwe, abhalwe encwadini u-Upton ayithunyelwe kwiRejista, futhi afakwa nasezithangamini ze-Raspberry Pi.
Okuthunyelwe kokuqala kwebhulogi, okumemezela i-Raspberry Pi PoE HAT kungaba thola lapha . Ikhasi lomkhiqizo elinezixhumanisi zabathengisi kabusha kulapha.
