Kab lus no tau txaus siab txhawb nqa los ntawm LCSC thiab JLCPCB.

LCSC Cov Khoom Siv Hluav Taws Xob - Ntau Hom Neeg Es Xias, Tus Nqi Nqis Npe Hnub no thiab tau txais $ 8 tawm ntawm koj thawj daim ntawv xaj.

JLCPCB ua cov qauv zoo PCBs rau tib neeg thoob plaws ntiaj teb. Lawv muaj ntau dua 300,000 tus neeg siv khoom thoob ntiaj teb nrog ntau dua 8000 xaj hauv ib hnub! Lawv muaj ntau dua 10 xyoo kev tsim khoom thiab muaj kev ntseeg tau zoo. Sim nws rau koj tus kheej thiab tau txais 10 PCBs rau tsuas yog $ 2 ntawm JLCPCB, Ua tsaug JLCPCB

Hauv cov lus qhia no, kuv yuav qhia koj yuav ua li cas ua koj tus kheej Arduino Nano.

Arduino Nano yog me me & breadboard-phooj ywg raws li ATmega328P Chip. Nws muaj ntau lossis tsawg dua qhov ua haujlwm zoo ib yam ntawm Arduino UNO tab sis hauv pob sib txawv. Nws tsis muaj DC nkaus nkaus xwb thiab ua haujlwm nrog Mini-B USB nkaus es tsis yog tus qauv B nkaus.

Cia peb pib

Kauj Ruam 1: Txhua Yam Peb Xav Tau

Nov yog cov npe ntu-

▶ AT Mega 328P-AU (LCSC)

▶ 16MHz Resonator (LCSC)

▶ Resistor Pack 2X4 - 1k ohm (0603) (LCSC)

▶ AMS1117 5V Regulator (LCSC)

▶ FT232RL - FTDI Chip USB rau UART (LCSC)

▶ LED Daj, Ntsuab & Liab (0603) (LCSC)

▶ 500mA fuse (0603) (LCSC)

N 100nF Capacitor (0603) (LCSC)

▶ 4.7uF Capacitor (1206) (LCSC)

▶ 1uF Capacitor (0603) (LCSC)

Di B2 Diode (LCSC) Cov

▶ USB chaw nres nkoj me me (LCSC)

▶ 2x3 Txiv neej Headers (LCSC)

▶ Txiv neej Headers (LCSC)

Kauj Ruam 2: Schematics thiab PCB

Txhawm rau ua PCB koj tuaj yeem siv dawb thiab yooj yim siv online EDA software EasyEda, tab sis nws yuav yooj yim dua kom tau txais cov ntaub ntawv dav dawb hau los ntawm Arduino qhov chaw thiab ntshuam lawv. Ua qhov kev hloov pauv uas koj xav tau, Kuv tau ua kuv cov PCB ntawm kev siv PDF version ntawm Nano Schematic, tab sis xaiv qhov twg los xij uas koj xav tsim PCB. Kuv xav txog kev ua cov PCBs hauv tsev tab sis nws yuav nyuaj heev yog li kuv tau txais lawv ua ntawm JLCPCB. Koj tuaj yeem tau txais 10 ntawm tsuas yog $ 2!

Kauj Ruam 3: Tua Nws Txhua Qhov Ua Ke

Feem ntau rau SMD koj yuav siv lub chaw tso cua kub los yog lub qhov cub ci rov qab tab sis kuv tsis muaj ib qho ntawm cov no (Kuv vam tias yuav hloov qhov no yav tom ntej) Yog li kuv tau muab cov no tso rau hauv. Kev siv tes txhuam SMD yog qhov yooj yim heev yog tias koj muaj cov cuab yeej raug thiab siv koj lub sijhawm.

QAUV

• nteg lub rooj tsavxwm rau ntawm lub tiaj tiaj txawm tias lub ntsej muag thiab kaw nws siv daim npog ntsej muag, vim nws yuav tsis ua rau daim npog ntsej muag puas tsuaj.
• Ua kom sov koj cov hlau mus rau 300 ° c thiab siv cov lus qhia zoo tshaj plaws uas koj muaj.
• Siv cov dej ntws mus rau thaj chaw uas koj tau siv ntau dua li ib qho ntawm cov pawm.
• Ua ntawv thov dua.
• Tsiv lub SMD tivthaiv mus rau hauv qhov chaw, nyiam dua nrog tweezers, thiab ua kom sov lub tinned ncoo kom rov ua dua lub lauj kaub.
• Tshaj li rov ua dua thiab ua kom cov pins thiab cov pawm uas seem.

Soldering TQFP pob

• Siv cov dej ntws los rau ntawm cov ntaub qhwv dua li ib daim ntaub qhwv.
• Ua ntawv thov ntau ntau ntawm cov pins ntau dua li siv cov laug txhuam los txhuam cov seem uas seem.

Kauj ruam 4: Hlawv Bootloader

Dab tsi yog bootloader?

Microcontrollers feem ntau tau teeb tsa los ntawm tus programmer tshwj tsis yog tias koj muaj ib qho firmware ntawm koj lub microcontroller uas tso cai txhim kho firmware tshiab yam tsis xav tau tus programmer sab nraud. Qhov no hu ua bootloader.

Yog tias koj nkag mus rau Arduino IDE koj yuav pom qhov piv txwv piv txwv hu ua 'Arduino as ISP.' Yog tias koj tso cov cai no rau koj Arduino, nws yuav pib ua haujlwm zoo li AVR programmer. Siv nws rub tawm Bootloader.

Yog tias koj xav tau kev qhia ntxaws ntxaws, txheeb xyuas Nematic's Video.

Kauj ruam 5: Thiab koj ua tiav

Tom qab txhua qhov kev ua haujlwm nyuaj koj tuaj yeem ua tiav Arduino Nano.

Yog tias koj nyiam qhov kuv ua koj tuaj yeem mus thiab tshawb xyuas kuv qhov blog (www.clebstech.com).

Thiab zoo li ib txwm muaj cov PCBs qub muaj los yuav daim ntawv nyob ntawd thiab cov no yuav dhau los sai sai!

Ua tsaug rau JLCPCB thiab LCSC uas ua rau tsab xov xwm no ua tau.

LCSC Cov Khoom Siv Hluav Taws Xob - Ntau Hom Neeg Esxias, Tus Nqi qis dua Sau npe hnub no thiab tau txais $ 8 tawm ntawm koj thawj daim ntawv xaj.

JLCPCB ua cov qauv zoo PCBs rau tib neeg thoob plaws ntiaj teb. Lawv muaj ntau dua 300,000 tus neeg siv khoom thoob ntiaj teb nrog ntau dua 8000 xaj hauv ib hnub! Lawv muaj ntau dua 10 xyoo kev tsim khoom thiab muaj kev ntseeg tau zoo. Sim nws rau koj tus kheej thiab tau txais 10 PCBs rau tsuas yog $ 2 ntawm JLCPCB, Ua tsaug JLCPCB
