QC thev naus laus zis yog qhov nthuav heev rau txhua tus neeg uas muaj lub xov tooj smartphone tab sis kuj yog DIY zej zog tuaj yeem tau txais txiaj ntsig los ntawm nws.
QC nws tus kheej yog qhov yooj yim. Yog tias "lub xov tooj smartphone hais tias -i xav tau lub zog ntau dua-" QC them nyiaj nce lub zog. Hauv 2.0 version muaj 5, 9, 12 (thiab 20) V. QC 3.0 tuaj yeem nce lossis txo qhov hluav taws xob hauv cov theem ntawm 200 mV.
Kauj Ruam 1: Nws Ua Haujlwm Li Cas:
Kuv xav tias txoj hauv kev zoo tshaj plaws kom nkag siab QC 3.0 yog nyeem qhov no (https://blog.rnix.de/12v-from-a-usb-powerbank/) kab lus hais txog version 2.0. Tshwj xeeb tshaj yog ntu "QuickCharge Handshake".
Hauv ntej:
1. thov 0, 4V-2V rau D+ (D- tsis txuas nrog)
2. siv qhov ntsuas hluav taws xob rau D+ thiab D- raws li qhia hauv cov lus ntawm no peb mus, tam sim no koj tuaj yeem nkag mus rau 9 lossis 12V (lossis 20V) hom (los ntawm txoj kev nws kuj woks nrog QC 3.0, vim 2.0 tau txhawb nqa)
Yog li dab tsi yog qhov dag kom xaiv peb qhov hluav taws xob hauv cov theem ntawm 200mV?
Cov ntawv no (https://www.mouser.com/ds/2/308/FAN6290QF-1099224.pdf), nplooj 12, qhia peb txoj hauv kev. Peb tsuas yog yuav tsum tau nkag mus rau "Hom Nruam" (raws li qhia hauv lub rooj | D+0.6V D- 3.3V |). Tam sim no peb nyob hauv hom tsis tu ncua. Txhawm rau nce qhov hluav taws xob rub D+ rau 3.3V rau lub sijhawm luv. Txhawm rau txo qhov hluav taws xob rub D- rau 0.6V rau lub sijhawm luv. (tau saib cov duab kos los ntawm
Kauj Ruam 2: Circuit Court Yooj Yim:
Ntawm no koj tuaj yeem pom ib qho yooj yim Circuit Court. Nws yog ib qho tseem ceeb heev los xaiv cov nyees khawm uas tsis tshua muaj pob. Txoj hauv kev zoo tshaj plaws yog tsim kom muaj lub khob cij nrog lub voj voog thiab ntsuas cov nyees khawm uas koj xaiv.
Kauj Ruam 3: Cov Lus Cim Ntxiv
- qhov ntsuas hluav taws xob tso tawm yog ib qho yooj yim los ntawm ali (https://www.aliexpress.com/wh lag luam wholesale? ltype= kev muag khoom & d=y&origin=y&isViewCP=y&catId=0&initiative_id=SB_20170424231520&SearchText=volt+meter&blanktest=0&tc=af
- yog tias koj xav nce mus txog 20V xaiv lwm tus tswj hluav taws xob, qhov no tuaj yeem ua haujlwm tsuas yog 15V, tab sis feem ntau (zoo li hauv kuv li) QC ntaus ntawv tsuas txhawb nqa txog 12V Kuv xav
- thaum txuas USB, disconnect D- ua ntej (jumper hauv kuv lub Circuit Court)
- Vim li cas ho tsis siv qib nce? Vim tias QC tuaj yeem muab lub zog ntau dua.
- nrog tus tiv thaiv qhov tseem ceeb (raws li qhia hauv daim duab) koj tsis tau txais qhov tseeb qhov hluav taws xob, tab sis rau kuv lawv tau ua haujlwm

Kev Saib Xyuas Lub Hwj Chim Nyob Nrawm thiab Kev Tshaj Tawm ntawm Lub Hnub Ci Raws Lub Hwj Huam Fais Fab: 10 Kauj Ruam
Kev Saib Xyuas Lub Hwj Chim Nyob Nrawm thiab Kev Tshaj Tawm ntawm Lub Hnub Ci Raws Lub Hwj Huam Fais Fab: Lub hom phiaj ntawm txoj haujlwm no yog txhawm rau saib xyuas thiab faib cov khoom siv hluav taws xob hauv lub tshuab hluav taws xob (hnub ci zog). Kev tsim qauv ntawm cov txheej txheem no tau piav qhia hauv cov ntsiab lus raws li hauv qab no. Lub kaw lus muaj ntau daim phiaj nrog kwv yees li 2 lub hnub ci ci nyob hauv
Zaj Lus Qhia 2: Siv Arduino Raws Li Lub Hwj Chim Rau Lub Hwj Chim: 6 Kauj Ruam
Zaj Lus Qhia 2: Siv Arduino Ua Lub Hwj Chim Rau Lub Hwj Chim: Nyob zoo dua, cov tub ntxhais kawm, rau kuv tshooj lus thib ob ntawm kuv chav kawm los qhia cov khoom siv hluav taws xob yooj yim. Rau cov uas tsis tau pom kuv thawj zaj lus qhia, uas piav qhia txog qhov tseem ceeb heev, kev pib ua haujlwm hauv Circuitry, thov saib tam sim no. Rau cov uas twb tau pom kuv yav dhau los le
