Qhov xwm txheej

Vim yog qhov tsim qauv yuam kev (lossis cov khoom pheej yig?) Qee qhov Raspberry Pi 3 (Pi) muaj teeb meem qis nrog ib txwm siv 5V cov khoom siv hluav taws xob. Hauv qhov xwm txheej hnyav, qhov hluav taws xob tuaj yeem poob qis 0.6 volts. Vim tias qhov hluav taws xob poob qis no Pi tuaj yeem qhia qhov kos npe hluav taws xob qis, ua rau tsis muaj zog - lossis tseem sib tsoo. Sab hauv Pi qhov hluav taws xob yuav tsum tsis pub tsawg dua 4.75 Volts kom nws ruaj khov.

Tsis tas li ntawd thaum koj siv Raspberry Pi ua lub chaw tshaj xov xwm - nws yuav yog qhov zoo kom tuaj yeem tig nws los yog tawm mus deb (Ntawm lub tshuab hluav taws xob).

Kauj ruam 1: Kev daws teeb meem

Txhawm rau zam qhov tsis ruaj khov Pi kuv tau teeb tsa tus nqi pheej yig (<30 Dollars) thiab muaj zog (5 ampere txog 6.5 Volt) lub zog hluav taws xob uas tuaj yeem tig los lossis tawm ntawm qhov chaw deb ntawm kev tswj chaw taws teeb (lub chaw taws teeb tswj los nrog "Kev Tswj Chaw Taws Teeb" (Kuv programmed nws lub teeb liab ntawm kuv Logitech Harmony chaw taws teeb tswj)).

Hloov chaw ntawm 5 ampere fais fab mov koj tuaj yeem siv tau 3 ampere ib qho - uas yuav loj txaus thiab koj tuaj yeem teeb tsa nws hauv rooj plaub me. Txawm hais tias ua kom ntseeg tau tias koj tuaj yeem hloov qhov hluav taws xob tso tawm nrog cov ntsia hlau hloov kho (ADJ).

Lub tswv yim yog kom nce qhov hluav taws xob tso tawm los ntawm 5 volts mus txog 5.5 volts.

USB cov lus qhia tshwj xeeb txhais tias USB cov khoom siv yuav tsum ua haujlwm los ntawm 4.45 Volts txog 5.5 Volts - yog li yuav tsum tsis muaj kev phom sij rau USB cov khoom siv.

Nrog ADJ-ntsia hlau koj tuaj yeem teeb tsa qhov hluav taws xob ntawm "Power Supply" los ntawm 4.5 txog 6.5VDC.

Hauv qhov kev sim thawj zaug kuv tau teeb tsa qhov hluav taws xob tso tawm ntawm 5.65 Volts thiab ntsuas ntawm USB-tso tawm ntawm raspberry pi txog 5.32 Volts. Qhov no txhais tau tias kuv Raspberry Pi muaj qhov ua tau sab hauv hluav taws xob poob ntawm 0.33 volts.

(Koj tuaj yeem pib qhov kev ntsuas nrog 5.2 Volts thiab maj mam nce mus txog thaum koj Raspberry Pi ruaj khov thiab lub zog qis ceeb toom tsis txaus ntseeg - ceev faj tsis txhob tua nws nrog overvoltage).

Hauv kuv qhov xwm txheej kawg kuv tau teeb tsa qhov hluav taws xob rau 5.5 volts - thiab txog tam sim no kuv tsis pom lub teeb liab qis dua.
