Peb tuaj yeem siv USB txuas rau lub zog LED teeb txij li lawv tuaj yeem xa 5V ntawm DC lub zog rau cov khoom siv kom deb ntawm USB saw.
Txawm hais tias muaj ob peb USB-powered teeb pom kev zoo nyob rau hauv kev ua lag luam, tsim koj tus kheej muab koj ntau dua daim ntawv versatility.
Cia peb saib yuav ua li cas los tsim peb tus kheej USB-powered LED teeb nrog qhov no hauv siab.
cov khoom uas xav tau los ua kom USB-powered LED teeb
Peb tuaj yeem xaiv SMD2835 lub teeb sawb ua lub teeb pom kev zoo vim peb xav kom peb tus kheej USB-powered LED teeb kom muaj kev hloov pauv ntau dua hauv lawv lub cev.
Tsis tas li ntawd, muaj ob txoj kab hluav taws xob uas txuas lub teeb ci LED mus rau USB 2.0 hom A tus pin socket muaj.
Ua cov khoom siv rau USB-powered LED teeb
Nov yog qee cov cuab yeej uas koj tuaj yeem siv los ua koj lub teeb ntxiv rau cov khoom siv rau USB-powered LED teeb:
hlau rau soldering
txiab rau stripping hlau
Yuav ua li cas los tsim koj tus kheej USB-powered LED teeb siv soldering hlau
Koj tuaj yeem pib tsim koj lub teeb tom qab koj tau txais cov khoom tsim nyog.
1. Txiav ib ntu ntawm koj lub teeb 'LED lub teeb sawb.
Txiav ib qhov ntev ntawm LED teeb sawb los ntawm lub kauj ua ntej. Txiav raws cov ntaub qhwv uas faib cov chips LED yog tias koj xaiv.
Yuav txiav USB LED Sawb teeb li cas KXZM
Ua tib zoo tawm ntawm qhov sib npaug ntawm qhov chaw nruab nrab ntawm cov kab txiav kom koj tuaj yeem muab lawv nrog qhov sib nrug txaus.
2. Txhawm rau txuas lub teeb ci LED mus rau lub hwj chim, txiav ib feem loj ntawm ob-tus neeg xyuas pib xaim.
Tom qab ntawd LED lub teeb sawb yuav tsum txuas nrog lub hwj huam mov los ntawm kev txiav ib feem loj ntawm 2- tus neeg xyuas pib xaim.
Tom qab txiav qhov xav tau cable, tshem tawm cov xov hlau los ntawm ob qho kawg kom koj tuaj yeem ua rau lawv.
3. Txuas ib lub xaim nrog lub teeb ci LED.
Cov hlau thiab LED lub teeb sawb tam sim no npaj tau los ua ke ua ke.
Koj tuaj yeem kaw lawv rau saum npoo thiaj li ua kom lawv sai dua.
Ua ntej soldering, coj mus rhaub cov hlau thiab LED teeb sawb rau saum npoo.
Tom qab ntawd siv cov hlau nplaum txaus txaus, tom qab ntawd muab cov xov hlau mus rau qhov tsim nyog cov ntaub qhwv ntawm LED sawb.
Tom qab soldering, LED lub teeb sawb thiab xaim yog tapping rau saum npoo.
Peb tau txuas cov xov hlau liab rau ntawm daim nplaum nplaum uas cim ntxiv, raws li qhia saum toj no, thiab cov hlau dub rau ntawm cov nplaum nplaum cim -.
4. Txuas lub qaum nrog USB 2.0 hom A connector.
Tam sim no peb muaj lub cable npaj, peb tuaj yeem muab nws rau peb USB 2.0 hom A pin connector.
Peb muaj peev xwm solder lub cable tsis siv ib tug multimeter txij li thaum peb twb tau txuas cov liab hlau rau ntxiv thiab dub hlau rau -.
