Yuav ua li cas yog ib tug USB-connector pinout

Universal USB-bus yog ib qho ntawm feem nrov computer interfaces. Lawv debuted nyob rau hauv 1997, thiab cia li peb xyoos tom qab, ib tug tshiab kev hloov kho ntawm (2.0), ceev los ntawm 40 lub sij hawm piv nrog rau thawj. Txawm li cas los, dua li no kev kawm, cov manufacturers pom tau hais tias cov kev ceev tsis txaus siv lwm nyuaj drives thiab lwm yam high-ceev kiag li lawm. Thiab tam sim no, ib tug tshiab USB-interface (ntaus 3.0). Tus txheej txheem tshiab yog ua zoo tshaj cov kev ceev ntawm lub yav dhau los version (2.0) 10 lub sij hawm. Qhov tsab xov xwm tsom rau xws li ib qhov teeb meem raws li tus pin ntawv ntawm lub USB-connector. Cov ntaub ntawv no muaj peev xwm yuav pab tau rau cov xov tooj cua amateurs uas nws tus kheej ua ib yam ntawm cov USB-adapter los yog ntaus ntawv yog powered ntawm lub USB-tsheb npav. Tsis tas li ntawd, xav txog dab tsi yog qhov pinout micro-USB USB-hom connector, thiab mini-USB.

piav qhia

Muaj ntau hams muaj ces yuav tsum muaj teeb meem thaum wrongly kev cob cog rua qhov chaw nres nkoj USB-bus powered by combustion fleshnakopiteley thiab peripherals. Kom tsis txhob rau tej lub sijhawm, nws yog tsim nyog tias USB-connector pinout tau nqa tawm kom zoo, nyob rau hauv raws li lees qauv. Connector hom USB 2.0 ib tug ca connector nrog plaub pins, nws muaj AF (BF) uas sau tias - "niam" thiab AM (VM) - "Dad." Micro-USB muaj tib lub daim ntawv lo, tsuas yog tus prefix micro, mini thiab lub hom ntaus ntawv, ntsig txog, - mini prefix. Lub ob hom txawv los ntawm tus txheej txheem 2.0 nyob rau hauv hais tias cov connectors twb tau muab siv rau 5 pin. Thiab thaum kawg, qhov kawg yam - qhov no USB 3.0. Outwardly, nws zoo li ib hom ntawm 2.0, tab sis nyob rau hauv xws li ib tug connector yog siv raws li ntau li ntau 9 hu.

Lub pin-hom USB connector

Cov xov connector USB-2.0 yog raws li nram no:

- tus thawj hlau (xim liab), thov kom nws ib tug DC mov voltage +5 V;

- ib tug thib ob hu (dawb), nws yog siv rau kis ntaub ntawv (D-);

- ib tug peb lub hlau (ntsuab), nws kuj yog los qhia cov lus qhia (D +);

- ib tug plaub hu (dub xim), nws yog noj cov mov voltage pes tsawg, tsis tau nws yog hu ua ib qho hlau.

Raws li twb tau hais saum toj no, lub hom micro thiab mini - ib tug tsib-pin USB connector. Cov xov hluavtaws rau cov no connector yog zoo tib yam rau lub hom 2.0, tsuas yog lub plaub thiab tsib pins. Plaub hu (lilac) - qhov no ID. Nyob rau hauv hom B connectors nws tsis koom nrog, raws li nyob rau hauv lub hom A connectors mus kaw cov hlau. Lub Xeem, Lub tsib davhlau ya nyob twg (Dub) - ib tug pes tsawg voltage.

Lub pin connector USB- hom 3.0

Tus thawj plaub hu yog zoo tib yam rau tus qauv 2.0, mus rau lawv peb yuav tsis tso tseg. Lub tsib hu (xiav) yog siv mus rau kis cov ntaub ntawv rau ib tug rho tawm kos npe rau USB3 (StdA_SSTX). Sixth xaus - tib yam, tab sis nrog ib tug ntxiv kos npe rau (daj). Xya - ntxiv earthing. Yim hu (purple) tau txais cov ntaub ntawv USB3 (StdA_SSRX) nrog ib tug rho tawm kos npe rau. Thiab thaum kawg, qhov kawg cuaj (txiv kab ntxwv) - tib yam li hais tias ntawm lub xya, tab sis nrog ib tug ntxiv kos npe rau.

Yuav ua li cas ua Thaiv USB-connector rau them?

Kev siv ntawm lub roj teeb charger USB-connector tsuas yog ob tug nyob ntawm tej: + 5V thiab cov kev sib cuag. Yog li ntawd, yog tias koj yuav tsum solder mus rau lub "xwb" hom connector USB 2.0 los yog 3.0, ces koj yuav tsum siv cov thawj thiab thib plaub hu. Yog hais tias koj siv ib tug mini los yog micro hom, nyob rau hauv uas cov ntaub ntawv uas koj yuav tsum fluster rau tus thawj thiab thib tsib terminals. Qhov tseem ceeb tshaj thaum fais fab yog thov - yog mus soj ntsuam cov polarity ntawm tus dais.
