Yintoni a pinout USB

Universal USB-ibhasi yenye kujongano PC kakhulu ethandwa. Ivumela uxhulumaniso serial yezixhobo (-E 127 iiyunithi). Kwakhona inkxaso izixhobo USB-bus ukuqhagamshelana kunye umsebenzi qhawula xa ibaleka PC. Ngaloo lesixhobo sinokubanamandla ngqo ngokusebenzisa element wathi, leyo akubikho mfuneko izinto ezongezelelweyo amandla. Kweli nqaku siza kukhangela yintoni eyenza pinout USB eqhelekileyo. Olu lwazi kunokuba luncedo self-ekwenziweni nayiphi USB-amaqhoshana okanye izixhobo ezifumana amandla nge elilujongano phambi kwethu. Ukongeza, siza kuhlolisisa into eyenza pinout micro-USB kwaye, kakade, mini-USB.

Inkcazelo kunye Cable USB-interface

Phantse wonke umsebenzisi computer uyakwazi oko kukhangeleka ngathi USB-isinxibelelanisi. Le ujongano isebenzisa uhlobo abane-tyaba A USB-isinxibelelanisi "umama" ayimakishileyo AF, yaye "Tata" - AM. Isikhonkwane USB Uhlobo A ubunjwe nabo ezine. Kwicingo lokuqala iphawulwa ebomvu, oko ondliwa DC ombane bavunyelwe +5 volts na ukuba asebenzise current ubuninzi 500 Ma. The contact yesibini - amhlophe - kuba data (D-). Kwicingo lesithathu (green) Iyasetyenziswa yokudlulisela data (D +). umfowunelwa yokugqibela iphawulwa emnyama, ke ndawalusa ombane yonikezelo zero (common).

Izihlanganisi uhlobo A kucingwa esebenzayo, ukuba uqhagamshele supply izixhobo (iikhompyutha, esilundwendwe lwakhe, njalo njalo. D.). Izihlanganisi zithathwa ukuba isixando, banamathele yi izixhobo ezifana abashicileli, yabavavanyi njalo njalo. Uhlobo izihlanganisi ezimbini isikwere kunye iikona chamfered. "Mama" na ilebhile BF, yaye "Tata" - BM. Le Uhlobo pin USB B na izikhonkwane efanayo ezine (amabini ngaphezulu kwaye ezimbini ngezantsi), ukuqeshwa - uhlobo A. ezifanayo

Zikagesi Connector Uhlobo Micro-USB

Izihlanganisi yale hlobo adla ngokusetyenziswa ukudibanisa iipilisi kanye Smartphones. Bona zincinane kakhulu umgangatho USB-interface. Enye into kukuba ubukho nabo ezintlanu. Zokumakisha kwezi izihlanganisi na ngolu hlobo lulandelayo: micro-AF (BF) - «Mother» kunye micro-AM (VM) - "Tata."

Uhlobo pin micro USB:

- yomfowunelwa wokuqala (ebomvu) kuba ombane sonikezelo + 5V;

- yesibini kunye iingcingo lesithathu (abamhlophe yaye eziluhlaza) esetyenziselwa ukugqithisa data;

- contact yesine Lilac (ID) zibe uhlobo Isidibanisi B engaganwanga, nezidibanisi lohlobo A, uyawavala phezu wire eqhelekileyo ukuxhasa OTG-umsebenzi;

- yokugqibela, eyesihlanu, qhagamshelana (abamnyama) - zero ombane.

Ngaphandle koku kungasentla, intambo kungaba esinye cingo esetyenziselwa 'sokuhluza'; inani onikwe kuye.

Isikhonkwane mini-USB

Mini-USB uhlobo isinxibelelanisi ziqulathe abafowunelwa ezintlanu. Phawula ezi izihlanganisi ngolu hlobo lulandelayo:. Mini-AF (BF) - «mama" ne mini-AM (VM) - "Tata" I-asayinimenti pin efanayo uhlobo micro-USB.

isiphelo

Ulwazi malunga imicwe desoldering kuba izihlanganisi USB sifanelekile kakhulu, ekubeni olu hlobo interface esetyenziswa phantse zonke iifowuni ze desktop kunye elektroniki. Ezi izihlanganisi asetyenziswa ukutshajisa lwangaphakathi kunye zodluliselo lwedata.
