Kuv ua qhov DC-rau-DC hloov pauv rau kuv 48V lub tsheb kauj vab hluav taws xob vim tias kuv xav kom muaj peev xwm ntsaws-hauv qee yam khoom siv 12V, xws li kuv lub xov tooj ntawm tes, lossis chav GPS.
Kauj ruam 1: Schematic
Ntawm no yog schematic. Lub hau qhov tseem ceeb yog qhov hloov pauv me ntsis nyob ntawm ntau npaum li cas koj tuaj yeem zam tau. Nco ntsoov xyuas qhov tseeb polarity rau lub kaus mom electrolytic. Kuv tsis muaj cov npe ntawm Digikey cov lej ib feem vim tias kuv pom ntau qhov ntawm qhov kuv xav tau ntawm lub khw hluav taws xob tshaj hauv ib cheeb tsam. Tab sis tag nrho cov ntu no (lossis qee yam ze) muaj los ntawm Digikey.
Kauj ruam 2:
Txij li thaum kuv pom ntau yam ntawm qhov kuv xav tau ntawm lub khw hluav taws xob hauv cheeb tsam, Kuv tsis muaj Digikey cov lej ib feem rau txhua yam, tab sis kuv tau sim nrhiav Digikey cov lej ib feem lossis hloov chaw uas ua tau. Cov txuas txuas yog nyob ntawm tus tsim kev txiav txim siab, cov khoom siv PC tawg yog qhov zoo rau cov txuas thiab cov xov hlau.
Kauj ruam 3: Txheej txheem
Qhov no yog qhov txheej txheem kev xav rau ib leeg-tog ib sab Circuit Board. Kuv tsis tau ua raws qhov no raws nraim thaum kuv tsim kuv tus protoytpe.
Kauj Ruam 4: Kev Tso Npe Tshooj Qauv
Qhov no qhia txog cov khoom siv tso rau ntawm lub rooj tsav tsheb perf (los ntawm Xov Tooj Cua). Kuv nyuam qhuav siv cov xov hlau txuas rau sab nraum qab ntawm lub rooj tsav tsheb kom txuas lub Circuit Court. Cov ntaub ntawv yog los ntawm lub xov tooj ntawm tes pov tseg. Nws tsis tau qhia hauv daim duab no, tab sis tom qab ntawd kuv txuas rau ntawm cov tooj liab ua kom sov mus rau U1 los pab ua kom nws txias. Rau kuv lub hom phiaj (xov tooj ntawm tes thiab GPS them roj teeb) Kuv tsis xav tias yuav muaj teeb meem cua sov los ntawm tus hloov pauv. Nco ntsoov siv qee cov roj cua sov thaum txuas ib lub dab dej sov.
Kauj Ruam 5: Npaj Them Tus Xov Tooj Ntawm Tes
Qhov no qhia txog qhov hloov pauv ua tiav nrog 12V luam yeeb-sib zog dongle uas haum rau ntsaws-hauv lub xov tooj ntawm tes them lossis lwm yam khoom siv 12V tsheb. Kuv yuav dongle ntawm lub khw muag khoom tsheb hauv ib cheeb tsam. Cov txiv kab ntxwv sib txuas yog ib qho tawm ntawm cov khoom sib txuas Kuv pom ntawm lub khw hluav taws xob ntau tshaj hauv ib cheeb tsam, tab sis yuav luag txhua 2-tus pin txuas hluav taws xob yuav ua haujlwm. Khaws cov khoom sib txuas los ntawm lub PC tawg fais fab mov yog qhov zoo ntawm cov txuas thiab xaim. Kuv mus me ntsis txuas vwm ntawm no; Kuv tsis xav tau ib qho txuas txuas ntawm 12V sab txij li cov luam yeeb-sib zog dongle tuaj yeem txuas ncaj qha mus rau lub khoos phis tawj. Nco ntsoov tias rooj plaub tsis kaw tag thiab kuv siv 4 nylon standoffs (epoxied hauv qhov chaw) kom ruaj ntseg rau saum. Kuv pom qhov no yog qhov tshwj xeeb vim tias nws tso cai rau airflow rau tus tswj hwm:-)
