Kuv nyiam ua kuv tus kheej PCBs, nws ua rau kuv txaus siab heev thiab kuv nyiam mloog nkauj ntau dua (kuv nyiam ib hom ntawv yog rap:)). Ntawm kuv lub rooj yeej ib txwm tsis muaj chaw txaus rau cov cuab yeej lossis cov khoom siv hluav taws xob, yog vim li cas kuv thiaj tsim cov qauv ntawm tus hais lus me me wireless.

Cov ntaub ntawv tau ua tiav ntawm PCB, txhua yam khoom siv hluav taws xob nyob saum toj. Kuv tuaj yeem mloog kuv cov nkauj nyiam nws ua tsaug rau Bluetooth module thiab yog tias kuv tau dhuav nws, kuv qhib lub xov tooj cua kom mloog xov xwm. Siv tus lej nkag, kuv teeb zaus ntawm lub teeb liab FM thiab nws tau tshwm rau kuv ntawm 0.96 OLED screen. Lub xov tooj them (USB C) yog lub luag haujlwm rau lub zog hais lus.

Koj yuav xav tau:

1. RDA5807 (1 $ Banggood)
2. ATMEGA328P-AU (1.5 $ Amazon)
3. 128x64 OLED I2C (4 $ Banggood)
4. SMD ENCODER (0.7 $ Banggood)
5. SMD TACT SWITCH (3 $ rau 50pcs Banggood)
6. Laminate (2 $ Banggood) lossis PCB tshaj lij (5 $ PCBWay)
7. Thiab qee qhov ntxiv (2 $)

Kauj Ruam 1: Schematic thiab Board hauv Eagle

Ua ntej, tsim txoj haujlwm tshiab (Cov Ntaub Ntawv -> Tshiab -> Txoj Haujlwm) thiab muab nws lub npe ("hais lus" hauv kuv qhov teeb meem).

Txoj cai -nyem rau ntawm qhov project thiab ntxiv.sch thiab.brd cov ntaub ntawv (Tshiab -> Schematic) (Tshiab -> Pawg Thawj Coj) rau nws. Qhib cov ntawv nrog qhov txuas ntxiv.sch thiab tom qab ntawd Tus Thawj Saib Xyuas Tsev Qiv Ntawv (Tsev Qiv Ntawv -> Qhib Tus Thawj Saib Xyuas Tsev Qhua). Tam sim no ntxiv cov tsev qiv ntawv uas koj yuav siv hauv koj txoj haujlwm (Muaj -> Xauj -> [koj lub tsev qiv ntawv] -> Qhib -> Siv). Koj tuaj yeem pib tsim cov phiaj xwm thiab thaum koj ua tiav nws yog lub sijhawm los tsim lub rooj tsavxwm (Tsim/hloov mus rau lub rooj tsavxwm).

Pib los ntawm kev txheeb xyuas qhov ntev ntawm cov nplais ntawm txheej txheej thiab txav tag nrho cov ntsiab lus rau nws. Raws li cov txheej txheem, txoj haujlwm yuav qhia koj tias koj xav tsim txoj hauv kev twg. Nrog cov lej sib txuas me me, nws tseem yuav ua rau lawv rau koj. Thaum koj tsim qauv yuav npaj tau koj tuaj yeem tshuaj xyuas koj li PCB zoo li cas nrog Online Gerber Viewer thiab ua tiav cov theem hauv qab no:

1. Nyem rau Layer Settings

2. Nyem rau Hide Layers

3. Kos Npe, Pads, Vias, Dimension raws li pom (yeem tNames thiab tValues)

4. Nyem OK

5. Nyem Luam thiab xaiv Daim iav, Dub, Khoom

6. Nyem OK

Thaum koj luam cov ntawv, nws yog lub sijhawm los tsim PCB.

Koj yuav tsum siv lub tshuab luam ntawv laser thiab ntawv lo (xws li 80g).

Kauj Ruam 2: Kev Npaj PCB

Koj yuav xav tau:

1. Sodium persulphate (B327)

2. Dej sov (60*C - 0.5l)

3. Ntawv txhuam (P1000)

4. Precision riam

5. Dremel nrog kev xyaum los ntawm 0.5mm txog 1mm

6. PIB

7. Hlau

8. Laminate

Pib los ntawm kev txiav cov laminate rau qhov ntev ntawm koj qhov project. Siv cov ntawv xuab zeb los txhuam sab saum toj ntawm cov laminate thiab ntxuav nws kom raug nrog isopropyl cawv. Thov daim ntawv rau laminate thiab ua kom sov nrog cov hlau teeb ntawm 3/4 lub zog rau li 3 feeb. Tam sim no, tsau txhua yam hauv dej sov thiab txhuam daim ntawv. Yog tias muaj qhov tsis xws tshwm sim, kho lawv nrog tus cwj mem cim. Lub sijhawm los npaj cov khoom noj - ncuav 100g ntawm sodium persulfate rau hauv lub khob nrog 0.5l dej sov thiab sib tov kom txog thaum cov hmoov yaj. Muab cov laminate tso rau hauv ib lub taub ntim thiab sib tov cov tshuaj kom ua kom nrawm dua cov txheej txheem. Thaum twg tsuas yog txoj hauv kev thiab tejzaum lwm cov ntsiab lus tsim, koj tuaj yeem rub tawm lub rooj tsavxwm thiab ntxuav nws hauv qab cov dej ntws. Ib zaug ntxiv, koj yuav tsum siv cov ntawv xuab zeb tshem tawm cov toner uas tsis tsim nyog. Koj tuaj yeem siv nws yam tsis muaj kev txhawj xeeb, koj yuav tsis ua rau txheej tooj liab puas. Txhua yam uas tshuav yog ua qhov thiab PCB tau npaj txhij!

Kauj ruam 3: Soldering

Lub sijhawm rau qhov ntxim nyiam tshaj plaws rau kuv kev ua ub no, uas yuav raug siv!

Rau cov khoom siv sib txuas SMD Kuv teeb txog 360*C ntawm cov hlau txuas. Siv cov dej ntws mus rau cov ntaub qhwv thiab tom qab ntawd muab cov tin me me tso rau ntawm ib qho ntawm lawv. Solder ib ntu ceg rau lub ncoo thiab tom qab ntawd ib qho ntxiv. Kuv pom zoo pib nrog cov ntsiab lus me tshaj plaws hauv Circuit xws li cov capacitors thiab resistors thiab xaus nrog tus lej nkag lossis hloov pauv - ua tsaug uas koj yuav pab txhawb txoj haujlwm no. Thaum tag nrho cov ntsiab lus nyob hauv qhov chaw koj tuaj yeem ntxuav lub phaj nrog isopropyl cawv.

Rov ua cov kauj ruam saum toj no nrog cov laug cam tom ntej thiab txuas lawv ua ke nrog goldpins.

Kauj ruam 4: Programming

1. Rub cov program los ntawm cov piv txwv rau koj Arduino - Arduino ua ISP.

2. Hlawv lub bootloader ntawm koj lub microcontroller

3. Tshaj tawm daim duab kos rau lub microcontroller

4. Qhov ntawd yog txhua yam!

Kauj ruam 5: Xeem

Koj tus neeg hais lus tau npaj txhij

Txhua yam koj yuav tsum ua yog txuas rau lub xov tooj them nyiaj thiab koj tuaj yeem mloog koj cov nkauj nyiam!

Lub suab zoo ua rau kuv xav tsis zoo, nws tsis yog tus hais lus rau saib cov yeeb yaj kiab, tab sis rau mloog nkauj nrog ntses bass thaj tsam zoo nws yog qhov txaus. Tus hais lus no tsuas yog tus qauv, muaj qee yam uas kuv xav hloov hauv nws. Tsis ntev kuv yuav xaj PCB los ntawm lub tuam txhab tshaj lij cuam tshuam txog kev tsim cov laug cam, kuv muab cov duab saum toj no.

Kuv yuav ua rau koj hloov kho tshiab txog qhov kev hloov kho!
