Hav! txhua tus Kuv lub npe yog Steve.

Hnub no kuv yuav qhia koj Yuav Ua Li Cas 60 Watt Portable Amplifier hauv Txoj Kev Yooj Yim heev siv TDA2050 ic nws yog ic nrov heev uas koj tuaj yeem pom hauv ntau lub tsev ua yeeb yam hauv tsev nws tuaj yeem muab lub zog siab tshaj ntawm 30 watts ntawm 4 ohms Nws xav tau ob lub zog siv hluav taws xob 24 0 24, Hauv qhov haujlwm no kuv tau siv 2 ntawm nws

Kauj Ruam 3: Daim duab Circuit Court

Koj tuaj yeem pom daim duab qhia chaw kom yooj yim dua

Kauj ruam 4: Sponsor

Kab lus hnub no tau txhawb nqa los ntawm lcsc.com

Lawv yog Cov Khoom Siv Hluav Taws Xob Loj Tshaj Plaws Los Ntawm Tuam Tshoj Npaj Yuav Nkoj Hauv 4 Teev Sijhawm thiab lawv xa thoob Ntiaj Teb

Nco tseg - Thov saib cov duab kom nkag siab zoo dua

Kauj Ruam 5: PCB Board Designing

Kuv Siv EasyEDA Los Tsim Kuv Li PCB Siv Daim Duab Duab Circuit muab los ntawm STMicroelectronics thiab nws coj kuv txog 2 teev los tsim

Koj tuaj yeem pom kuv tau siv XT30 rau cov lus hais tawm kom yooj yim ntsaws thiab ua si

Koj tuaj yeem rub tawm Gerber Cov Ntaub Ntawv

Gerber & Circuit Diagram -

Kauj Ruam 6: Txiav txim rau PCB

Nowa Hnub nws tau yooj yim heev los xaj PCBs thiab nws tsis raug nqi koj ntau, Yog lawm koj yooj yim ua qhov no hauv Pawg Thawj Coj tab sis PCB Zoo li txoj hauv kev zoo dua li Perf Board thiab nyab xeeb rau ua haujlwm Yog li koj tuaj yeem tso haujlwm me me thiab nyiaj txiag kom tau txais Kev Ntsuam Xyuas Zoo

Txog Qhov Haujlwm no, Kuv tau siv PCBGOGO Kev Pabcuam rau Kev Tsim Kuv Cov PCB thiab nws siv sijhawm li 24 Teev los Tsim Kuv Cov PCBs thiab hauv 7 Hnub lawv tau xa nws mus rau kuv lub qhov rooj Cov kauj ruam thiab qhov zoo tsuas yog xav tsis thoob

Nco tseg - Thov saib cov duab kom nkag siab zoo dua

Kauj ruam 7: Soldering

Kuv tau sau tag nrho cov khoom siv thiab siv tag nrho cov Kev Tiv Thaiv ua ntej, thiab tom qab ntawd muab cov Capacitors Raws Li Daim Duab Circuit Court thiab siv Cutter los txiav txhua ceg ntxiv

Thiab tom qab ntawd kuv tau Soldered XT30 Connector

Tom qab ntawd, Kuv tau Soldered Main Ic TDA2050 nws coj kuv li 30 feeb

Nco tseg - Thov saib cov duab kom nkag siab zoo dua

Kauj Ruam 8: Sawv Tawm

Kuv siv 4 sawv tawm los muab nws qee qhov kev tshem tawm

Nco tseg - Thov saib cov duab kom nkag siab zoo dua

Kauj Ruam 9: Tshav Kub Kub

Kuv tau siv Qhov Loj Qhov Tshav Kub Kub Shink rau Tshav Kub Kub dissipation nws yog qhov tsim nyog yuav tsum tau siv Cov Tshav Kub Kub Tsuag Yog Tsis Li Koj Yuav Hlawv Cov Chip

Thiab nws yog ib qho tseem ceeb heev uas yuav tsum tau siv cov khoom ua kom sov zoo kom sov kom sov zoo

Kuv tau thov me ntsis kom muaj cov cua sov sib xyaw rau TDA2050 IC thiab ua kom nruj nrog lub rhaub dej kub

Nco tseg - Thov saib cov duab kom nkag siab zoo dua

Kauj Ruam 10: Cov Khoom Siv Hluav Taws Xob

Kuv siv 2 SMPS txhua 24V @ 6 Amps muab tag nrho 48V @ 6 Amps

SMPS txuas nrog hauv Series "Nws hu ua Daul Power Supply"

+24 - 0 - 24 V

Koj tseem tuaj yeem siv Transformer Raws Lub Hwj Huam Muab Khoom tsis muaj teeb meem nrog qhov ntawd

Kauj ruam 11: Teeb thiab Txaus Siab

Ua ntej kuv tau txuas tus Hais Lus nrog XT30 Txuas

Qhov thib ob kuv tau txuas 3 Lub Hwj Huam Hluav Taws Xob rau lub zog siv hluav taws xob ob

Thib peb Kuv tau txuas 2 lub suab tso suab cable ntawm txiv neej header

Yuav ua li cas tsuas yog siv lub zog siv hluav taws xob thiab ua zaj nkauj "Txaus Siab"

Hwj chim Mov

• Tsis zoo - Dub Cable
• Hauv av - Ntsuab Cable
• Zoo - Liab Cable

Cov tswv yim tawm tswv yim

• 1st Txiv neej Header - Txoj Cai Tawm Tswv Yim
• 2st Txiv neej Header - Sab laug Tawm Tswv Yim

Hais Lus Tawm

• 1st XT30 Connector - Tus Hais Lus Zoo
• Thib ob XT30 Txuas - Sab Nraud Hais Lus
