Hav guys! Kuv vam tias koj twb nyiam kuv cov ntawv tshaj tawm dhau los txog "Bluetooth AT Commands Settings" thiab koj tau npaj rau qhov tshiab, ib txwm kuv tau ua qhov kev qhia no los qhia koj ib qib zuj zus thaum koj ua koj tus kheej daim npav lag luam PCB txij li kuv pom nws ua ib qho txoj haujlwm zoo kawg uas suav nrog kev kawm hluav taws xob thiab PCB tsim thiab nws tuaj yeem yog qhov pib zoo rau cov pib tshiab txhawm rau txhim kho lawv cov txuj ci.

Thaum ua qhov haujlwm no, peb tau sim ua kom ntseeg tau tias cov ntawv no yuav yog cov lus qhia zoo tshaj plaws rau koj txhawm rau pab koj yog tias koj xav ua koj tus kheej daim npav lag luam PCB, yog li peb vam tias daim ntawv no muaj cov ntaub ntawv xav tau.

Txoj haujlwm no tau yooj yim los ua tshwj xeeb tom qab tau txais cov ntawv luam tawm tshwj xeeb uas peb tau xaj los ntawm JLCPCB txhawm rau txhim kho qhov pom ntawm peb Cov Lag Luam Lag Luam thiab tseem muaj cov ntaub ntawv txaus thiab cov lej hauv phau ntawv qhia no tso cai rau koj tsim koj daim npav lag luam zoo nkauj.

Peb tau ua txoj haujlwm no tsuas yog 2 hnub nkaus xwb, tsuas yog ib hnub kom tau txais txhua qhov uas xav tau thiab ua tiav cov cuab yeej tsim khoom thiab sib sau ua ke, tom qab ntawd ib hnub los npaj cov cai kom haum rau peb tes num.

Koj yuav kawm dab tsi los ntawm qhov haujlwm no:

1. Txiav txim siab kho vajtse kom raug.
2. Npaj daim duab kab hluav taws xob txuas rau txhua qhov khoom siv uas tau xaiv.
3. Tsim qhov tsim nyog PCB tsim.
4. Muab cov khoom siv hluav taws xob tso rau PCB.
5. Pib qhov kev sim thawj zaug thiab lees paub qhov haujlwm.

Kauj Ruam 1: Daim duab Circuit Court

Raws li ib txwm hais mav, Kuv sim txhua lub sijhawm kom khaws qee qhov khoom siv hluav taws xob zoo thiab yooj yim thiab thawj kauj ruam hauv peb txoj haujlwm yog Circuit Diagram uas yuav hloov pauv mus rau PCB tsim.

Txhawm rau npaj cov txheej txheem kuv tau siv EasyEDA cov cuab yeej tsim uas yog qhov ua tau zoo tshaj plaws rau ob tus pib thiab tus kws tshaj lij PCB tsim, nws muaj lub tshuab ua piv txwv rau ntsuas ntsuas thiab lub tsev qiv ntawv tsim tau zoo uas koj tuaj yeem pom txhua yam khoom siv xav tau rau koj tsim hluav taws xob nrog lawv cov hneev taw tsim nyog.

Peb lub voj voog yog ib qho yooj yim, nws muaj USB txuas rau lub zog siv hluav taws xob thiab ATMega328 microcontroller qhov twg peb yuav txuas tsib RGB LEDs uas tau tswj los ntawm peb lub khawm thawb, txhua qhov khoom siv ntawm no yog SMD qhov tshwj tsis yog USB txuas uas yog los ntawm lub qhov ib feem

Kauj Ruam 2: Ua PCB

Tom qab taug qab cov kab koj yuav muaj cov phiaj xwm npaj txhij los hloov pauv mus rau hauv PCB tsim.

Tsuas yog nyem rau ntawm kev hloov pauv rau PCB tsim thiab txhua yam peb xav tau tam sim no yog teeb tsa PCB tus qauv los teeb tsa Daim Npav Ua Lag Luam loj.

Qhov loj ntawm pawg thawj coj yog qhov tseem ceeb kom haum rau tib neeg lub hnab ris thiab hnab nyiaj yog li kuv tau ntsuas qhov ntsuas uas muaj tam sim no uas muaj cov qauv txheej txheem tib yam ntawm daim npav ua lag luam 54.75mm x 85.50mm ces kuv tau rov qab mus rau EasyEDA cov cuab yeej tsim los tsim pawg thawj coj tus qauv uas ua raws qhov ntsuas qhov ntev.

Tam sim no peb rub thiab tso cov khoom hauv pawg thawj coj saib thiab peb pib sau cov ntaub ntawv ntiag tug xws li lub npe tag nrho, txoj haujlwm, chaw nyob thiab kev sib cuag raws li txheej silkscreen.

Tom qab ntxiv qee lub cim txias thiab cov cim lub rooj tsavxwm tau npaj rau kev rov ua dua thiab txhua yam nws yuav siv yog kev xa cov khoom no, txhawm rau kom kuv lub npe sau rau hauv cov khoom siv ua tiav kub (ENIG) Kuv teeb nws raws li txheej txheej npog sab saum toj tab sis ceev faj thaum taug kev pawg thawj coj no koj yuav tsum zam kev sib cuag ntawm ob txoj kab ntawm ob lub nets sib txawv nrog rau sab saum toj daim npog qhov ncauj qauv lossis nws yuav luv dua.

Kauj Ruam 3: PCB Chaw Tsim Khoom

Tam sim no peb tsim tau npaj rau kev tsim khoom yog li txhua yam peb xav tau yog tsim cov ntaub ntawv GERBER thiab xa lawv mus rau JLCPCB rau kev xaj khoom, tsuas yog teeb tsa qee qhov kev tsim khoom PCB xws li PCB xim uas yog xim dub lossis koj tuaj yeem xaiv xim twg muaj xim koj nyiam thiab ENIG qhov ua kom tiav kom muaj xim zoo nkauj thiab PCB tuab tau teeb tsa rau 0.4mm kom muab nws zoo li daim npav lag luam tiag.

Kuv xaj 50 daim ntawm pawg thawj coj no raws li kev sim thiab kuv tau muab nws tso rau hauv kev tsim khoom nrog qee qhov lwm yam PCB tsim kom tau txais lawv txhua tus xa hauv ib pob ntawv xaj

Tsuas yog plaub hnub tos thiab kuv tau txais kuv cov PCBs zoo xa nrog khoom plig txias los ntawm tus muag khoom.

Nov yog peb cov PCBs tsim tau zoo heev thiab koj tuaj yeem pom cov xim kub ua tiav ntxiv saib zoo dua ntawm cov PCB dub thiab tseem lub rooj tsav xwm tuab yog raws nraim li peb tau teeb tsa txoj haujlwm zoo heev los ntawm JLCPCB ib txwm muaj.

Txog peb qhov kev tsim kuv pom qee qhov yuam kev sau tom qab muab lub rooj tsav khoom tsim tawm yog li sim zam qhov no thiab kuv kuj tau txais lus qhia los ntawm qee pab pawg tsim khoom siv hluav taws xob txog kev tso QR code hloov qhov txuas ntawm no.

Kauj Ruam 4: Software Tshooj & Kev Xeem

Tam sim no peb txav mus rau ntu software, raws li kuv tau hais peb yuav muaj ATmega microcontroller ntawm Arduino Nano pawg thawj coj uas yuav pab peb kom tso saib peb qhov sib txawv ntawm RGB LEDs thiab ntawm no yog nws cov lej cuam tshuam los ntawm cov ntawv hauv qab no.

Tam sim no txhua yam peb yuav tsum tau ua yog siv tag nrho cov khoom siv rau peb PCB.

Tom qab ua tiav kev sib dhos, tsuas yog lub zog 5V sab nraud txaus los ua lub zog rau lub rooj tsavxwm thiab koj tuaj yeem pib ua si nrog cov duab no.

Thov nco ntsoov tias qhov no tsuas yog ua piv txwv ntawm kev sib txuas hauv Circuit Court thiab koj tsis tas yuav muab cov khoom sib txuas rau txhua lub laug cam vim tias koj tuaj yeem siv cov PCBs no raws li nws yog rau kev sib cuag lag luam.

Ua raws li cov lus qhia no, koj tuaj yeem ua rau koj daim npav ua lag luam txaus los qhia rau ntiaj teb paub tias koj muaj peev xwm thiab muaj tswv yim li cas. Tab sis tseem muaj lwm qhov kev txhim kho kom ua tiav hauv peb txoj haujlwm txhawm rau ua kom nws muaj butter ntau dua, yog vim li cas kuv yuav tos koj cov lus los txhim kho nws, tsis txhob hnov qab ntiv tes xoo cov kab lus no yog tias koj nyiam.

Ib qho kawg, nco ntsoov tias koj ua hluav taws xob txhua hnub.

Nws yog BEE MB los ntawm MEGA DAS pom koj lub sijhawm tom ntej.
