Umhla we izolo bendithetha ngekiti eyona nto iphambili kwiRaspberry pi, egxile kwintengiso yabantwana abanomdla wokwakha ikhompyuter yabo.
Ewe, kwiveki ephelileyo, Abasebenzisi abaninzi beRaspberry Pi abathenga iplagi yePoE HAT baqala ukwenza inani lamabango kwiiforamu ezahlukeneyo nkqu nakwibhlog yeRaspberry.
Kuba abasebenzisi abaninzi uxele imicimbi ngeRaspberry Pi Power-over-Ethernet HAT esandula ukukhutshwa, I-Raspberry Pi Foundation ibonelela ngokubuyisela abathengi abathengile ibhodi engalunganga.
Kwiintsuku emva kokukhululwa kwayo ngo-Agasti abasebenzisi bebexela umda kumandla azisiweyo nguRaspberry Pi PoE HAT.
I-HAT iyancedisana neRaspberry Pi 3 Model B + SBC eyaziwayo enegunya lokutshintsha amandla ngokupheleleyo kunye ne-37-57V DC, igalelo leCandelo 2 kunye nemveliso ye-5V / 2.5A DC.
La I-HAT iqhagamshela kwisinxibelelanisi se-pin-40 kunye ne-PoE ekhethekileyo ye-4-pin header eyaziswa nge-B +, emi kufutshane namazibuko e-USB.
El I-PoE HAT ibonelelwa nge-25 x 25mm fan brushless ukupholisa i-Broadcom SoC.
Kodwa ngelishwa, le nto ayizukufumana kakuhle kwimarike ngenxa yale ngxaki sele ikhankanyiwe.
Ngexesha leeveki ezingenelelayo, iinjineli kwiRaspberry Raspberry Pi Foundation ziye zangxama ukufumana uhlobo lwengxaki. Intshukumo enomdla inokulandelwa kwiiforamu zeRaspberry Pi.
Malunga nengxaki
Kwinqaku kwiRejista , ingxaki ichazwe ngu-Eben Upton, Umseki kunye nomsasazi weRaspberry Pi Trading.
Ngokuka-Upton:
"Olu lunxibelelwano phakathi kwesilawuli sokutshintsha kwamaxesha asezantsi kwi-HAT kunye nolunye lweempawu ezimbini zenguqulo ezinciphisa i-USB esizisebenzisayo kwibhodi ephambili."
Iippton ichaze ukuba ngenxa yokuba umlawuli usebenza ngokufanelekileyo kwisantya esiphantsi, ngalo lonke ixesha uyitshintsha, ushenxisa isixa esikhulu samandla kwii-caps ezintathu zokugcina i-USB ngotshintsho lwangoku lokunciphisa.
Eli xesha langoku likhulu ngokukhohlisa ukutshintshela ekucingeni ukuba isiganeko sokwenene esenzekayo senzeka.
“Silahlekile kuvavanyo lweemveliso kuba (esisidenge ithamsanqa) uvavanyo lwethu lomthwalo olunzima lwenziwe kwiibhodi ngolunye uhlobo lweswitshi, kwaye uninzi lwabavavanyi bethu basebenzise kuphela ibhodi ukunika amandla iimpuku kunye neebhodi zezitshixo, ezisebenza kakuhle. Siye sazivavanya iipere zeHAT / Pi, ”utshilo u-Upton.
Amanqaku aphambili eRaspberry Pi PoE HAT Iingxaki, kwaye amanyathelo athathiweyo acacisiwe kwileta u-Upton yathunyelwa kwiRejista, kwaye zaye zafakwa nakwiiforamu zeRaspberry Pi.
Ezi zilandelayo:
- “Inani elibalulekileyo lezibini ze-HAT / Pi zikhawulelwe ekuhambiseni ngaphantsi kwe-200 mA ye-current river yangoku kwi-USB. Oku kwanele ngokubanzi kwiimpuku kunye neebhodi yezitshixo, kodwa hayi kwiidrive ezinzima, umzekelo «.
- "Siza kuyilungisa le ngxaki kuhlobo lwamva lwe-PoE HAT."
- "Okwangoku, siza kongeza inqaku apho i-HAT ithengiswa khona, sibhala lo mda."
- Siza kubonelela ngeendlela ezimbalwa zeemodyuli kubasebenzisi abanomdla. Banokuba zezi:
- "Ukususa iminqwazi yeetanki kwibhodi ephambili (indlela elula necocekileyo ukuba ungasebenzisa isinyithi, kodwa inciphisa uqhagamshelo lwe-USB)."
- "Faka isixa esincinci kuthintelo lothango kwindlela yangoku ukusuka kwi-HAT (oku kuya kuba nzima ukuphumeza)."
- Amanqaku aphambili eengxaki zeRaspberry Pi PoE HAT, kunye namanyathelo athathiweyo, abhalwa kwileta u-Upton yathunyelwa kwiRejista, kwaye yathunyelwa nakwiiforamu zeRaspberry Pi.
Iposti yokuqala yebhlog, ebhengeza iRaspberry Pi PoE HAT inokuba njalo fumana apha . Iphepha lemveliso elinamakhonkco kubathengisi ilapha.
