Yog li muaj ib tuj ntawm cov lus qhia qhia txog kev siv lub teeb ci ci ci. Ntau ntawm lawv siv kev lag luam muaj Buckpuck los ntawm Luxdrive. Coob leej ntawm lawv kuj tseem siv cov cai tswj kab hluav taws xob uas tawm ntawm 350 mA vim tias lawv tsis muaj txiaj ntsig zoo. Cov lus qhia no ua haujlwm los qhia rau tib neeg paub tias muaj lwm txoj hauv kev xaiv los tsav lub zog loj. Peb tau los rau txoj haujlwm no hauv txoj haujlwm peb tab tom ua nrog cov neeg siv khoom rau lub zog loj coj strobe [www.ohararp.com/blog.html] Lub plawv ntawm txoj haujlwm no yog STCS1 los ntawm STM Electronics: https://www.st.com/stonline/khoom/ntawv nyeem/ds/13415/stcs1.htm Kev Ceeb Toom: Qee qhov ntawm txoj haujlwm no tau tsim thiab ua kom zoo siv software thiab kho vajtse zoo. Txawm li cas los xij, txhua yam ntawm kev tsim qauv no tuaj yeem ua tiav siv qhib cov khoom lag luam lossis qee lub rooj sib txig sib luag thiab xaim qhwv.

Kauj Ruam 1: Nyeem Cov Ntawv Qhia

Thawj kauj ruam nrog txhua qhov haujlwm hluav taws xob yog nyeem cov ntaub ntawv: https://www.st.com/stonline/products/literature/ds/13415/stcs1.pdf Los ntawm qhov no peb tuaj yeem pom qee qhov tseem ceeb ntawm cov nti no: ■ Mus txog 40 V input voltage ■ Tsawg dua 0.5 V voltage nyiaj siv ua haujlwm ■ Mus txog 1.5 A tso tawm tam sim no ■ PWM dimming tus pin ■ Shutdown tus pin ■ LED txiav kev txiav txim siab kuaj mob

Kauj Ruam 2: Peb Xav Tau Lwm Yam Dab Tsi? Npaum Li Cas 5V@20mA

Vim tias kuv xav kom qhov kev tsim qauv no muaj qhov yuav luag zoo ib yam li BuckPuck los ntawm Luxdrive Kuv txiav txim siab ntxiv qhov yooj yim 5V@20 mA

Kauj Ruam 3: Teeb tsa PCB

Siv kev sib txuas ntawm cov txheej txheem txheej txheem koj lub rooj tsav xwm rau kev teeb tsa yooj yim tshaj plaws li ua tau. Qhov no yuav siv sijhawm me ntsis tab sis koj lub siab ntev ntawm no yuav ua haujlwm zoo rau koj. Qhov no siv rau txhua txoj kev teeb tsa. Ntawm no koj tuaj yeem pom meej tias peb tab tom siv 1206 pob rau txhua qhov ntawm peb cov resistors, capacitors, thiab diodes.

Kauj ruam 4: Wired Up

Nov yog txhua yam txuas nrog. Hmoov tsis zoo peb yuav tsum siv lub dav hlau hauv qab thiab qee qhov vias kom ua tiav txoj haujlwm no. Nov yog Cov Ntaub Ntawv Gerber ntawm pawg thawj coj no.

Kauj Ruam 5: Txiav txim thiab teeb tsa Pawg Thawj Coj

Siv koj tus neeg muag khoom pcb uas koj nyiam tshaj thiab cov txheej txheem sib dhos koj tuaj yeem tso ua ke ntawm pawg thawj coj zoo nkauj sai. Peb nyiam https://www.goldphoenixpcb.biz/ rau peb cov laug cam thiab tom qab ntawd peb siv kapton stencils, kester solderpaste, thiab lub lauj kaub tais diav rov qab los yog qhov cub kom sib sau peb cov laug cam.

Kauj Ruam 6: Cia Qhov Tsis Pom Kev Pib

Nrog rau. 1 kev sib nrug ntawm tus pinout ntawm pawg thawj coj no koj tuaj yeem yooj yim breadboard koj txoj haujlwm. Ntawm no peb tab tom txhawb txoj hlua ntawm 3 x K2 Luxeons (140 lumens ib coj) los ntawm 12V phab ntsa wart muaj peev xwm muab 3000 mA. Qhov kev ua tau zoo Ntawm qhov nti no zoo nkauj heev. Ntawm 1500 mA lub rooj tsav tsheb tsis tshua sov rau qhov kov thaum tsav tsheb coj mus txuas ntxiv. mount lawv mus rau lub rhaub dej kom tshem tawm cov cua sov uas tau tsim tawm. Txhua ntu rau qhov tsim qauv no tuaj yeem pom ntawm Mouser lossis Digikey: Nov yog BOMDriver IC - STCS1
