Yuav ua li cas yog ib tug USB pinout

Universal USB-bus yog ib qho ntawm feem nrov PC interfaces. Nws tso cai rau serial kev twb kev txuas ntawm pab kiag li lawm (127-E units). Tsis tas li ntawd txhawb USB-bus pab kiag li lawm txuas thiab disconnect muaj nuj nqi thaum khiav ib lub PC. Yog li tus ntaus ntawv yuav powered ncaj qha los ntawm lub hais tias lub caij, uas eliminates qhov xav tau rau ntxiv khoom siv fais fab. Nyob rau hauv no tsab xov xwm peb yuav saib li cas yuav muab ib tug txheej txheem USB pinout. Cov ntaub ntawv no muaj peev xwm yuav pab tau rau nws tus kheej-kev siv ntawm tej USB-adapters los yog pab kiag li lawm uas txais lub hwj chim ntawm lub interface ua ntej peb. Nyob rau hauv tas li ntawd, peb yuav kawm txog dab tsi tshwm sim tawm ib micro-USB pinout thiab, ntawm chav kawm, mini-USB.

Hauj lwm thiab Cable USB-interface

Yuav luag txhua txhua lub computer neeg siv paub dab tsi nws zoo li tus USB-connector. Qhov no interface siv ib tug plaub-pav ca hom A USB-connector "niam" tau cim AF, thiab "Dad" - AM. Lub pin USB hom A yog muaj li ntawm plaub hu. Tus thawj hlau yog cim nyob rau hauv liab, nws yog noj DC voltage +5 volts yog tso cai ua ntaub ntawv thov ib tug tshaj plaws tam sim no ntawm 500 ma. Qhov thib ob hu - dawb - rau cov ntaub ntawv (D-). Qhov thib peb hlau (ntsuab) kuj yog siv rau kis cov ntaub ntawv (D +). Xeem hu yog cim nyob rau hauv dub, nws yog noj cov mov voltage zero (cov).

Connectors hom A yog suav tias yog active, lawv muaj kev cob cog mov pab kiag li lawm (computers, party, thiab hais txog. D.). Connectors pom tau hais tias yuav nyob rau hauv lub passive, lawv cov keeb los ntawm pab kiag li lawm xws li printers, scanners thiab thiaj li nyob. Lub hom connectors yog ob square nrog chamfered cov ces kaum. "Niam" yog BF daim ntawv lo, thiab "Dad" - BM. Lub pin USB hom B muaj tib lub plaub pins (ob rau sab saum toj thiab ob hauv qab no), lub sij hawm - ib tug zoo tib yam hom A.

Thaiv Connector hom Micro-USB

Connectors ntawm no hom mas feem ntau yog siv los txuas ntsiav tshuaj thiab smartphones. Lawv yog cov ntau me tshaj ib tug txheej txheem USB-interface. Lwm feature yog lub xub ntiag ntawm tsib hu. Npav cov connectors yog raws li nram no: micro-AF (BF) - «Niam» thiab micro-AM (VM) - "Dad."

Lub pin micro USB hom:

- tus thawj hu (liab) rau cov mov voltage + 5V;

- thib ob thiab thib peb nyob ntawm tej (dawb thiab ntsuab) siv rau cov ntaub ntawv kis tau tus mob;

- plaub hu lilac (ID) rau hauv lub connector hom B yog tsis koom, thiab connectors ntawm hom A, nws kaw rau cov hlau mus txhawb OTG-muaj nuj nqi;

- kawg, tus thib tsib, hu rau (dub) - pes tsawg voltage.

Dhau li ntawm tus saum toj no, cov cable tej zaum yuav muaj lwm hlau siv rau "soj ntsuam kuaj cov"; tus xov tooj yog tsis muab rau nws.

Lub pin mini-USB

Mini-USB connector hom kuj muaj tsib hu. Mark cov connectors raws li nram no: mini-AF (BF) - «niam" thiab mini-AM (VM) - "Dad." Lub pin ntawv yog zoo tib yam rau lub micro-USB hom.

xaus

Ntaub ntawv hais txog desoldering nyob ntawm tej rau lub USB connectors yog heev tseem ceeb, vim qhov no hom ntawm interface siv nyob rau hauv yuav luag tag nrho cov mobile thiab desktop pab kiag li lawm thiab gadgets. Cov connectors yog siv rau cov uas them lub internal roj teeb thiab rau cov ntaub ntawv kis tau tus mob.
