2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

Txij li xyoo 2015 kuv tab tom txhim kho txoj haujlwm zoo no kom muaj qhov yuav luag txwv tsis pub tshaj tawm kev cai nruab nrab ntawm kuv lub tsheb. Muaj ib hnub kuv txiav txim siab coj lub koom haum mus rau xov tooj ntawm qhov ntawd nrog lub tsev tsim ua pcb pawg thawj coj. Cov duab saum toj no yog nyob rau theem dav dav, yog li muaj qee cov xov hlau nthuav tawm. Qhov board no tuaj yeem hloov kho rau koj tus kheej xav tau yog tias paub siv CAD software.

Siv nws ntawm koj tus kheej RISK. Qee cov kauj ruam uas tau piav qhia yog ua rau muaj kev phom sij ntau txoj hauv kev (muag nrog Cov Hluav Taws Kub Kub, Txheej Txheem Tshuaj, Hluav Taws Xob, ETC). Ceev faj

Kauj Ruam 1: Cov cuab yeej xav tau

• Ib phau ntawv driller
• Hlau laug
• laug
• Lub tshuab nqus tsev nqus dej
• Daim ntawv yees duab

Kauj Ruam 2: Cov Khoom Npe

• ferric tshuaj dawb
• phenolite phaj
• tus pin header 2x20 rau raspberry Pi 2
• tus pin header ib kab

Kauj ruam 3: Software

Txij li nws tsis yog lub ntsiab lus ntawm cov lus qhia no, kuv tsuas yog muab cov ntawv uas muaj cov ntawv rau mod raws li koj xav tau. Software siv yog EAGLE CAD 7.5.0 freeware version:

Yooj yim siv tau yooj yim Graphical Layout Editor

Kauj ruam 4: Exporting Layers Monochromatic

Dav dawb hau cad muaj qhov kev xaiv xa cov ntawv ua duab, tab sis ua ntej qee cov txheej yuav tsum tau muab zais:

CEEB TOOM:

• Qee cov txheej tau muab zais (peb tsis xav kom lawv luam tawm)
• Raws li qhov no yog ob tog ntawm pawg thawj coj saib muaj 2 cov duab xa tawm kom tiav (saum thiab hauv qab)
• xa duab li 300 dpi (xaiv monochromatic yuav tsum tau tshuaj xyuas)

Tom qab xa tawm siv lwm qhov software (kuv siv GIMP) los muab tshuaj txhuam ntau zaus rau hauv tib daim ntawv thiab tom qab ntawd xa tawm ua pdf

Tsis txhob teev cov duab !!

Kauj Ruam 5: Hloov Toner

1. Txiav cov phaj phenolite ze rau qhov loj ntawm raspberry board
2. Laum lub qhov yog lub tswv yim zoo los ua daim duab duab phim lub rooj tsav xwm loj thiab txoj haujlwm raug
3. Koj tuaj yeem laum qee qhov ntawm tus pin header ntawm daim ntawv thiab pawg thawj coj saib thiab siv tus pin kom phim cov haujlwm
4. Txiav daim ntawv me me kom loj dua los siv qee daim kab xev, txij li ob sab saum toj thiab hauv qab tau kov nrog lub rooj tsavxwm siv qee daim kab xev kom nws ua ke
5. Npog daim phiaj npaj nrog qee daim ntaub qub (t-shirt tej zaum tau quav) ntawm ob sab
6. Siv cov hlau ua ob peb feeb ntawm qhov kub siab tshaj plaws ntawm ob sab

Tsis txhob xav phem yog tias tsis tau txais thawj zaug. Tsuas yog xyaum muab qhov tseeb kom paub txoj hauv kev. Saib cov duab kuv thawj zaug sim (ua tsis tiav, ua tsis tiav, tsis ua tiav) thiab nws tsuas yog ib sab xwb tsis muaj lub dav hlau hauv av. Tam sim no kuv muaj peev xwm los ua ob tog sab

Kauj Ruam 6: Ntxuav Board thiab Etching Solution

1. Thaum lub suab hloov pauv tau npaj tiav yog lub sijhawm tshem tawm daim ntawv yees duab, ntxuav nws nrog qee yam kom tshem tawm cov ntawv uas seem tab sis tsis muaj tshem cov toner.
2. Npaj ferric chloride raws li cov lus qhia los ntawm tus muag khoom
3. Ntxiv xaws xov rau hauv ib qho ntawm lub qhov ntawm lub rooj tsavxwm
4. Sink lub rooj tsavxwm ntawm kev daws teeb meem thiab tso nws tseg, los ntawm lub sijhawm dhau mus tshuaj xyuas nws thiab ua qee qhov kev txav mus los kom tsis xav tau tooj liab txheej, rov ua cov txheej txheem no kom txog thaum tsuas yog cov khoom seem pcb.
5. Tom qab qhuav thiab huv si siv cov ntaub plaub los tshem tawm cov toner thiab nthuav tawm cov kab tooj liab

Cov phiaj xwm txuas ntawm no yog rau ob tog sab nrauv thiab kuv tsis muaj cov duab ntawm txheej txheem txheej txheem ntxiv lawm

Kauj Ruam 7: Drilling thiab Soldering

Raws li lub rooj tsav xwm hauv tsev thiab ua ob sab txoj hauv kev pheej yig los txuas rau saum toj mus rau hauv qab yog siv qee cov xov hlau txuas. Pawg me me tsis yog teeb meem.

1. Siv phau ntawv siv lub tshuab ua kom lub qhov ua tib zoo
2. Txuas tus pin headers thiab cov khoom siv
3. Solder txhua yam

Qee cov kauj ruam ntxiv yog qhov tsim nyog kom ua tiav thiab ua rau nws tiv thaiv los ntawm kev tuav tab sis kuv tsis tau ua tiav theem no.

Kauj Ruam 8: Mounting thiab Testing

Lub rooj tsavxwm ntawm daim duab tseem tsis tau muaj ob sab los ntawm no ua rau kuv txhim kho nws kom muaj qhov zoo dua tab sis cov yam ntxwv yuav luag zoo ib yam.

• FM breakout board SI4703
• Serial GPS module muaj
• 2 teb encoders
