PCB kuv tsim tau hu ua Audio Alert. Lub rooj tsavxwm no tau muab tso nruab nrab ntawm lub tso suab tso suab thiab cov neeg siv suab tso suab xws li lub tshuab xa xov FM lossis lub suab nrov. Thaum lub rooj sib tham wirelessly tau txais cov lus xa tawm nws tawg mus rau hauv lub suab tawm los ntawm qhov chaw tam sim no thiab ua si MP3 suab clip cuam tshuam nrog cov lus tau txais. Tom qab qhov clip ua tiav lub rooj sib tham hloov rov qab mus rau qhov qub (hauv kuv cov ntaub ntawv iPod.)

Kuv tsim lub rooj tsavxwm no ua pawg thawj coj rau pawg thawj coj saib kuv tsim los txhawm rau txheeb xyuas thaum kuv lub khw khaws cov hmoov av puv. Txawm hais tias cov plua plav khaws tag nrho lub rooj tsavxwm yuav tig lub teeb nyem, Kuv tseem yuav qee zaum tsis pom nws. Lub khw nrov nrov heev thaum tus neeg khaws cov plua plav thiab lwm yam cuab yeej nyob ruaj khov tau ua haujlwm yog li kuv yuav luag ib txwm hnav kuv lub ntsej muag tiv thaiv nrog tus txais FM built-in. Siv lub rooj tsav xwm no tam sim no kuv hnov "Tus plua plav khaws tag nrho" txawm hais tias kuv tus tiv thaiv kev hnov lus. Saib

Lub mcu siv yog ATmega328p. MCU tau txais kev ceeb toom los ntawm RFM69CW tus xa xov. Lub suab hloov yog I2C tswj PT2314 nti. PT2314 yog 4 mus rau 1 lub tso suab tso tawm. Pawg thawj coj nthuav tawm 2 ntawm 4 qhov ua tau tawm tswv yim raws li tus qauv 3.5mm lub tso suab tso suab. Lub hauv paus thib 3 yog lub nti MP3 player nyob rau hauv, thiab qhov thib 4 tsis siv. Cov zis yog dhau los ntawm tus qauv 3.5mm lub tso suab tso suab.

Lub MP3 player muaj 3 qhov ua tau: daim npav SD, USB Stick, thiab NOR Flash.

Tus neeg siv MP3 zoo ib yam YX5200-24SS nti pom ntawm ntau DF Player modules (txawm hais tias feem ntau ntawm cov qauv uas pheej yig dua ntawm cov qauv no siv cov chips cuav uas tsis muaj tag nrho cov kev ua haujlwm ntawm thawj lub nti.) -24SS nti yog tias nws yog lub tso suab thiab nws txhawb NOR Flash EEPROM.

Koj tuaj yeem npaj NOR Flash nrog MP3 kaw lossis siv ib qho ntawm lwm qhov chaw. Thaum pib lub MP3 player yuav pib rau USB yog tias nws muaj, ua raws los ntawm daim npav SD, thiab tom qab ntawd NOR Flash. Koj tuaj yeem hloov kho software kom hloov pauv qhov ua ntej, lossis muaj MP3 qhov chaw raws li cov lus tau txais.

Raws li programmed, cov lus tawm tswv yim sab nraud tau dhau los ntawm cov zis. Ib yam li MP3 qhov chaw, tus cwj pwm no tuaj yeem hloov pauv hauv software. Tsis tas li ntim, sib npaug, treble, thiab ntau lwm yam suab hloov pauv tuaj yeem tswj tau los ntawm software.

Pawg thawj coj tseem muaj qhov kev xaiv ntxiv lub mloog pob ntseg lub tshuab ua kom nrov nrov. Kuv siv lub tshuab ua suab nrov hauv kuv kev teeb tsa vim tias cov zis tso tawm FM transmitter thiab lub tshuab xa tawm ua tau zoo dua nrog lub tshuab raj ntau dua li thaum nws pub kab theem suab.

Tag nrho cov pins uas tsis tau siv tau raug coj los rau ntawm ntug ntawm lub rooj tsavxwm. Pawg thawj coj muaj I2C txuas nrog kab cuam tshuam rau kev txhim kho yav tom ntej (zaub, keypad, thiab lwm yam..)

Schematic tau muab zais rau hauv cov kauj ruam tom ntej.

Raws li nrog rau lwm cov laug cam kuv tau tsim, pawg thawj coj saib cov ntaub ntawv no tau muab sib qhia ntawm PCBWay.

Lub tshuab luam ntawv 3D muaj nyob ntawm Thingiverse:

Kauj Ruam 1: Cov lus qhia rau kev teeb tsa Pawg Thawj Coj

Cov lus qhia rau kev teeb tsa lub rooj tsavxwm (lossis yuav luag txhua lub rooj tsavxwm me me) ua raws. Hauv cov kauj ruam hauv qab no kuv tau teeb tsa lub rooj tsavxwm yam tsis muaj lub mloog pob ntseg xaiv tau.

Yog tias koj twb paub yuav tsim SMD pawg thawj coj saib, hla mus rau kauj ruam 13.

Kauj Ruam 2: Sau Qhov Chaw

Kuv pib los ntawm kev xaub ib daim ntawv mus rau lub rooj ua haujlwm nrog cov ntawv lo rau txhua qhov me me (cov neeg tiv taus, lub tshuab hluav taws xob, LEDs). Tsis txhob tso cov capacitors thiab LEDs nyob ib sab. Yog tias lawv sib xyaw, nws yuav nyuaj rau qhia lawv sib nrug.

Tom qab ntawd kuv sau cov ntawv nrog cov ntu no. Nyob ib ncig ntawm ntug kuv ntxiv lwm qhov, yooj yim los txheeb xyuas qhov chaw. (Nco ntsoov tias kuv siv tib daim ntawv no rau lwm cov laug cam kuv tau tsim, yog li tsuas yog qee qhov chaw hauv daim duab muaj cov khoom nyob ib sab ntawm/ntawm daim ntawv lo)

Kauj ruam 3: Mount Board

Siv ib qho me me ntawm cov ntoo ua ib qho thaiv thaiv, Kuv txiav cov PCB pawg thawj coj ntawm ob daim ntawm seem pawg thawj coj saib. Cov laug cam tsab ntawv tau tuav rau ntawm qhov thaiv nrog ob daim kab xev (tsis muaj kab xev ntawm PCB nws tus kheej). Kuv nyiam siv ntoo rau qhov thaiv thaiv vim nws ib txwm tsis coj/tiv thaiv. Tsis tas li nws yooj yim txav nws ib ncig raws li xav tau thaum tso cov khoom.

Kauj Ruam 4: Thov Muab Tshuaj Txhuam Txhuam

Thov siv cov tshuaj txhuam txhuam txhuam rau hauv SMD pawm, tawm hauv ib qho los ntawm cov ntaub qhwv qhov muag. Ua txoj cai, Kuv feem ntau ua haujlwm los ntawm sab laug mus rau sab xis kom txo qis txoj hauv kev los pleev cov tshuaj txhuam uas kuv twb tau thov lawm. Yog tias koj txhuam cov tshuaj txhuam, siv cov ntaub so tsis lo xws li cov uas tshem tawm pleev. Tsis txhob siv Kleenex/ntaub so ntswg. Kev tswj tus nqi tshuaj txhuam rau txhua lub ncoo yog qee yam uas koj tau txais los ntawm kev sim thiab ua yuam kev. Koj tsuas yog xav tau me me dab ntawm txhua lub ncoo. Qhov loj ntawm dab yog txheeb ze rau qhov loj thiab cov duab ntawm lub ncoo (kwv yees li 50-80% kev pab them nqi). Thaum tsis ntseeg, siv tsawg dua. Rau cov pins uas nyob ze ua ke, zoo li ICs hauv TSSOP pob, koj siv daim kab xev nyias nyias hla txhua daim ntaub es tsis txhob sim siv cais dab rau txhua qhov ntawm cov pawm nqaim no. Thaum cov laug tau yaj lawm, daim npog qhov ncauj yuav ua rau cov laug txav mus rau hauv lub ncoo, yam zoo li cas cov dej yuav tsis lo rau saum npoo av. Cov laug yuav hlais lossis txav mus rau thaj chaw uas muaj daim ntaub qhwv.

Kuv siv qhov qis melting point solder paste (137C Melting Point)

Kauj Ruam 5: Muab Qhov Chaw SMD

Muab cov khoom SMD. Kuv ua qhov no los ntawm sab laug mus rau sab xis hauv qab, txawm hais tias nws tsis muaj qhov sib txawv ntau dua li koj tsis tshua muaj peev xwm plam ib feem. Cov khoom siv tau muab tso rau hauv cov tshuab hluav taws xob. Kuv nyiam lub tweezer nrog qhov kawg nkhaus. Xaiv ib feem, tig lub thaiv thaiv yog tias xav tau, tom qab ntawd tso ib feem. Muab txhua ntu kom pom lub teeb kom ntseeg tau tias nws tau zaum tiaj tus ntawm lub rooj tsavxwm. Thaum tso ib feem kuv siv ob txhais tes los pab ua kom raug. Thaum tso lub xwmfab mcu, khaws nws kab pheeb ces kaum los ntawm cov ces kaum sib txawv.

Txheeb xyuas lub rooj tsav xwm kom ntseeg tau tias txhua lub tshuab ua haujlwm sib txawv nyob hauv qhov chaw raug, thiab txhua daim ntawv qhia tau raug.

Kauj Ruam 6: Sijhawm rau Cov Cua Kub Phom

Kuv siv YAOGONG 858D SMD Kub Cua Phom. (Ntawm Amazon tsawg dua $ 40.) Pob suav nrog 3 lub taub hau. Kuv siv lub taub hau loj tshaj (8mm). Cov qauv/qauv no yog tsim los lossis muag los ntawm ntau tus neeg muag khoom. Kuv tau pom kev ntaus nqi thoob plaws qhov chaw. Rab phom no tau ua haujlwm zoo rau kuv.

Kuv siv cov tshuaj ntsuas kub tsawg. Rau kuv rab phom qauv kuv muaj qhov kub tau teev tseg rau 275C, tso pa tawm mus rau 7. Tuav rab phom sib dhos rau ntawm lub rooj tsavxwm ntawm kwv yees li 4cm saum lub rooj tsavxwm. Cov laug nyob ib ncig ntawm thawj ntu yuav siv sijhawm ib pliag kom pib yaj. Tsis txhob ntxias kom ua kom nrawm dua los ntawm kev txav phom ze rau ntawm lub rooj tsavxwm. Qhov no feem ntau ua rau tshuab qhov ib ncig. Thaum cov laug yaj, txav mus rau ntu sib tshooj tom ntej ntawm pawg thawj coj saib. Ua hauj lwm koj txoj kev nyob ib ncig ntawm lub rooj tsavxwm.

Kauj Ruam 7: Txhawb Ntxiv Yog Xav Tau

Yog tias lub rooj tsavxwm muaj lub ntsej muag txuas rau SD daim npav txuas lossis lub ntsej muag teeb lub suab, thiab lwm yam, thov siv cov xaim txuas ntxiv rau cov ntaub qhwv uas siv los txuas nws rau lub rooj tsavxwm. Kuv tau pom tias cov tshuaj txhuam ib leeg tsis yog feem ntau muaj zog txaus los ua kom cov khoom no ntseeg tau.

Kauj Ruam 8: Ntxuav/tshem tawm SMD Flux

Cov kua nplaum uas kuv siv tau tshaj tawm tias yog "tsis huv". Koj yuav tsum tau ntxuav lub rooj tsavxwm, nws zoo li zoo dua thiab nws yuav tshem tawm cov hlaws me me ntawm cov laug ntawm lub rooj tsavxwm. Siv cov yas, nitrile, lossis hnab looj tes roj hmab hauv qhov chaw muaj cua nkag tau zoo, nchuav me me ntawm Flux Remover rau hauv cov tais me me lossis cov tais diav tsis huv. Reseal lub raj mis tshem tawm. Siv txhuam txhuam, txhuam tus txhuam hauv cov tshuaj tshem tawm thiab txhuam thaj tsam ntawm lub rooj tsavxwm. Rov ua dua kom txog thaum koj tau txhuam cov laug cam. Kuv siv rab phom txhuam txhuam rau lub hom phiaj no. Cov plaub hau yog tawv dua li txhuam txhuam feem ntau.

Kuv nchuav qhov tsis siv flux tshem tawm rov qab rau hauv lub raj mis. Kuv tsis paub tias qhov no puas yog lossis tsis yog. Kuv tsis tau pom dua ib qho teeb meem ntsig txog ua qhov no.

Kauj Ruam 9: Muab thiab Muab Tshuaj Txhuam Tag nrho Trough Qhov Qhov

Tom qab cov dej tshem tawm tau tshem tawm ntawm lub rooj tsavxwm, tso thiab txhuam tag nrho txhua qhov ntawm qhov nqaum dej, luv tshaj rau siab tshaj, ib zaug.
