He aha ka pilina USB?

'O ka USB kelepona kekahi o nā kikowaena pūnaewele kaulana loa. Ua ho'olimalima'ia lākou i ka makahiki 1997, a ma hope iho o'ekolu makahiki, ua'ike'ia kahi hō'ailona hou (2.0), ua ho'onui'ia e 40 mau manawa i ka ho'ohālike'ana me ka mea mua. Eia na'e, me ka holomua'ana o ia mea, ua'ike nā mea hana i ka hiki'ole o ka wikiwiki e ho'ohana i nā'ōpala ikaika o waho a me nā mea ho'ohana'ē a'e. A i kēia manawa, ua'ike'ia he kāpili pūnaewele hou (type 3.0). 'O ka pā'ani hou loa i'oi aku ka wikiwiki o ka version (2.0) i nā manawa he 10. Ho'opili'ia kēia'atikala i ka hopena e like me ke kīpili o ke pūnaewele USB. Hiki ke ho'ohana i kēia'ikepili i nā leka uila e hana i kekahi mea hana ki'i USB a i'ole nā pūnaehana e loa'a ana i ka mana ma o ke USB pūnaewele. Eia hou, e no'ono'o i kahi pilina o kahi pūnaewele USB e like me ka micro USB a me ke kelepona.

Hō'ike

He nui nā'elele lelele i hālāwai me kahi pilikia i ka wā i lawe'ia kahi port USB kūpono'ole i ka puhi'ana o nā puku a me nā kikowaena. I mea e pale ai i kēlā'ano kūlana, pono pono ka ho'onohonoho'ana o ka pūnaewele USB e like me nā paepae i'aelike'ia. 'O ke kāpili USB 2.0 he ala pālahalaha me nā lālani'ehā, ua maka'ia'o AF (BF) - "mom" a me AM (BM) - "papa". 'O ka'ōnaehana USB me ka'ōkuhi like'ole, me nā micro prefix, a me nā mea like'ole me ka'ōpili, -'o ke prefix mini. 'O nā'ao'ao hope'elua i like'ole i ka 2.0 o ka'ike inā he 5 mau pilina ma kēia mau mea ho'ohui. A'o ka hopena,'o ka pūnaewele hou loa'o USB 3.0. Ma waho, ua like kona'ano 2.0, akā i loko o kēia pūnaewele ka ho'ohana i 9 mau pilina.

'O Pinout o nā mea ho'ohui USB

'O ka pinout o ka pūnaewele USB 2.0 penei:

- keeaea (keokeo), ua lako ia me ka volumoku volumoku DC o +5 V;

- i ka lua o ka hui '(keʻokeʻo), ka mea, ua hoʻohana' ia no ka pū i hiki 'ike (D-);

- ke kolu o ka'ele (kala'ula), ua mana'o'ia ho'i no ka ho'ololi'ike (D +);

- ka'aha'ehā (ka'ele'ele'ele'ele), ua hānai'ia me ka volley supply voltage, a ua kapa'ia'o ka leka uila.

E like me ka mea i'ōlelo mua a'e nei,'o nā micro a me nā'ano li'ili'i he pūnaewele USB elima. 'O ka pinout o kēia mea pūnaewele he'ano like ia me ka 2.0, koe wale no ka mau hāhā a me ka lima. 'O ka hā o ka hulina (lilac kala) ka ID. I ka loea o ka B i ho'ohana'ole ia, akā, i ka hui pū'ana o ke'ano A, ua pa'a lākou i kahi leka ma'amau. 'O ka hope,'o ka pae'elima (ka'ele'ele'ele'ele) ka helu'ole o ka puhi kuni.

Ke kui hūlili USB- type 3.0

'O nā papahana'ehā mua loa e like me ka 2.0 2.0,'a'ole mākou e noho ma luna o lākou. Ho'ohana'ia ka lima (blue) i ka lawe'ana i ka'ike me ka hō'ailona o ka USB3 (StdA_SSTX). 'O ke ono o ka hopena, ho'okahi nō ia, akā me ka hō'ailona keu (ke kalamelena). 'Ehiku - mau hana hou. 'O ka'ewalu'oki (pale) no ka loa'a'ana o ka data USB3 (StdA_SSRX) me kahi hō'ailona li'ili'i. A eia ka mea hope, o ka hope eiwa (alani) - ka like me ia o ka hiku, akā, me ka hua hoʻohui.

Pehea wau e wehe ai i ka pūnaewele USB no ka uku'ana?

E ho'ohana wale'ia kēlā me kēia loiloi i'elua mau'ea mai ke kāpili USB: + 5V a me kahi hulina ma'amau. No laila, inā makemake'oe e ho'okau i ka USB o ka "charging" USB 2.0 a 3.0 paha, a laila, pono'oe e ho'ohana i nā helu mua a me ka hā. Inā'oe e ho'ohana i nā'ano li'ili'i a me nā'ano micro, i kēia hana, pono e ho'okomo i nā hopena mua a me ka'elima. 'O ka mea nui loa ke ho'ohana'ia ka mana, e nānā i ka pola o ka mea.
