Uyini pinout-USB

Universal-USB ibhasi ingenye ethandwa kakhulu PC interface. It ivumela uxhumano serial amadivayisi (127-E amayunithi). Futhi ukusekela zamadivayisi e-USB-ibhasi xhuma uphinde unqamule umsebenzi uma isebenza PC. Ngakho idivayisi kungenziwa inikwa amandla yi ngqo ngokusebenzisa isici wathi, okwenza kungabi nesidingo olungeziwe segezi. Kulesi sihloko sizohlola kuyini nokuthi ngezimbobo ze-USB pinout. Lolu lwazi ingaba wusizo for self-womshini noma iyiphi-USB adapters noma amadivayisi ukuthola amandla nge esibonakalayo phambi kwethu. Ngaphezu kwalokho, sizohlola kuyini nokuthi pinout-micro-USB kanye, yebo, mini-USB.

Incazelo kanye Cable USB-interface

Cishe wonke amakhompuyutha umsebenzisi uyazi ukuthi kubukeka kanjani USB-isixhumi. Lokhu interface isebenzisa uhlobo ezine-flat-USB-isixhumi "umama" uye imakwe AF, futhi "Ubaba" - AM. Iphikhodi-USB Type A yakhiwa oxhumana ezine. I wire kuqala ephawulwe abomvu, it is fed DC voltage +5 volts ovunyelwe sisebenzise zamanje esiphezulu 500 ma. Eyesibili contact - omhlophe - I- idatha (D-). I wire wesithathu (green) liyasetshenziswa ngokudlulisa idatha (D +). contact Kugcine ephawulwe omnyama, it is fed supply voltage oholayo (ezivamile).

Nezixhumi uhlobo A kubhekwa asebenzayo, ukuthi yizinto ezihlobene supply amadivayisi (amakhompyutha, aphethe, nokunye. D.). Izixhumi ubhekwa le yokwenziwa, sihlanganyela nabo amadivayisi ezifana abanyathelisi, scanner nokunye. Izixhumi uhlobo ezimbili isikwele nge emakhoneni chamfered. "Mama" kuyinto BF ilebula, futhi "Ubaba" - BM. Uhlobo pin USB B has efanayo izikhonkwane ezine (ezimbili phezu futhi ezimbili ngezansi), aphoyintimenti - i ezifanayo uhlobo A.

Wiring Isixhumi Uhlobo-Micro-USB

Nezixhumi yalolu hlobo avame ukusetshenziswa ukuxhuma amaphilisi kanye Smartphones. Kodwa zincane kakhulu ukwedlula indinganiso ye-USB esibonakalayo. Esinye isici kuba phambi oxhumana ezinhlanu. Ukumaka lezi nezixhumi simiswe ngalendlela lelandzelako: micro-AF (BF) - «Umama» futhi micro-AM (VM) - "Ubaba."

Uhlobo pin intambo ye-USB:

- Ungowokuqala okuxhunyanwa naye (obomvu) nokulethwa voltage + 5V;

- yesibili futhi izintambo wesithathu (omhlophe noluhlaza okotshani) esetshenziselwa ukuthutha idatha;

- contact wesine Lilac (i-ID) ku isixhumi uhlobo B engakathenjiswa umshado, futhi nezixhumi ohlobo A, uyawavala phezu wire ezivamile ukusekela OTG-umsebenzi;

- zokugcina, owesihlanu, contact (black) - zero voltage.

Ngaphandle kwezinto ezibalwe ngenhla, ikhebula kungaba esinye wire esetshenziselwa "ukuhlolwa"; nombolo alinikeziwe kuye.

Iphikhodi mini-USB

Mini-USB Isixhumi hlobo luqukethe oxhumana ezinhlanu. Mark lezi nezixhumi kanje:. Mini-AF (BF) - «mama" futhi mini-AM (VM) - "Ubaba" I izabelo pin ncamashí uhlobo micro-USB.

isiphetho

Ulwazi mayelana desoldering izintambo ngoba nezixhumi USB efanele kakhulu, kusukela kulolu hlobo esibonakalayo esetshenziswa cishe wonke amadivaysi mobile kanye desktop nasezintweni zobuchwepheshe zamuva. Lezi nezixhumi asetshenziselwa ukushaja ibhethri yangaphakathi futhi ukudluliswa kwedatha.
