Ua tus kws tsim khoom siv hluav taws xob, Kuv ib txwm xav kom muaj lub ntsuas hluav taws xob tiv thaiv nqa tau, uas tuaj yeem ntsuas txhua qhov khoom siv hluav taws xob nyob ntawd. Hauv xyoo 2016, Kuv tau tsim kuv tus kheej ib qho Kev Ntsuas Kev Ntsuas raws AVR TransistorTester los ntawm Markus F. thiab Karl-Heinz Kübbeler. Lub caij ntuj sov no, kuv xav tias, nws puas tuaj yeem ua qhov loj me me? Txij li thaum kuv qhov kawg yog qhov loj heev thiab nyuaj rau nqa ib ncig.
Kuv pib rov tsim PCB nrog SMD cov khoom thiab cov duab OLED vim nws me me, lub teeb yuag, thiab siv hluav taws xob tsawg. Kuv xav khaws cov txiv tsawb jacks txij li thaum lawv muab cov cuab yeej ntsuas ntsuas zoo thiab ua rau nws zoo dua. Hais tias, Kuv tuaj yeem siv SMD tweezer probes rau kev sim SMD cov khoom lossis hais tias kuv tuaj yeem siv tus nab kuab lossis lwm yam. Kuv tsis txwv rau ntsaws rau hauv kuv ib feem rau tus ntsuas kom sim nws.
Tom qab siv ob peb teev fiddling ncig PCB txheej txheem, Kuv tswj kom coj nws mus rau me me li 58mm x 32mm (2.28in x 1.26in). Me me zoo nkauj, txoj cai? Txhawm rau kom nws haum raws li cov saw hlau, Kuv tau ntxiv qhov xuas nrig rau hauv qab kaum sab xis ntawm PCB yog li koj tuaj yeem tso rau hauv lub nplhaib tseem ceeb lossis hlua zoo nkauj. Tus ntsuas ntsuas pib sai li sai tau thaum koj lub zog los ntawm USB C.
Thaum koj txuas tus tivthaiv, nias lub pob nyob ib sab ntawm cov zaub kom pib ntsuas. Txij li nws tsuas muaj ib lub pob, nws ua rau nws siv tau yooj yim dua thiab ua rau nws zoo li tsis yooj yim li lub tshuab ntsuas hluav taws xob, uas yuav tshwm sim nyuaj rau siv thaum xub thawj rau ntau tus neeg siv. Tsis tas li, txhawm rau mus rau cov ntawv qhia zaub mov tus neeg siv tsuas yog xav tau ob npaug nias lub pob ib zaug ib feem tau raug sim lossis "Tsis muaj lub vijtsam tiv thaiv pom".
Kuv siv 0805 cov khoom ntim rau cov ntsuas vim tias lawv yog cov khoom me me uas ib tus tuaj yeem siv tau los ntawm txhais tes thiab tuaj yeem ua qhov muag ncaj qha yam tsis muaj lub tsom iav loj. Kuv siv cov tshuaj txhuam txhuam nrog rau cov cua kub rov ua dua lub cuab yeej los txhawm rau txhawm rau hauv cov khoom siv.
Ua tsaug ntau rau PCBWAY rau kev txhawb nqa lub tsev no
PCBWay tau hais kom nqis tes thiab pab kuv txhawb txoj haujlwm no. Lawv kuj tau muab lawv cov kev pabcuam PCB rau kev tsim. Kuv tau txais PCBs hauv kev them nqi matte-tiav soldermask uas tsuas yog hloov kho tag nrho tsim kom muaj txiaj ntsig zoo ntawm tus ntsuas. Lawv muab 10 tus PCBs kev cai rau qis li $ 5 nrog rau ntau qhov kev xaiv xws li xim xim muag, qhov ua tiav, thiab ntau ntxiv. Lub sijhawm tawm mus rau PCBs tau nrawm heev. Kuv tau txais kuv cov PCBs xa hauv 3 hnub txij li hnub kuv tau xaj. Lawv kuj tshuaj xyuas txhua tus PCB tsim tus kheej ua ntej tsim khoom yog li koj tsis tau txais ib qho PCBs puas. Kuv pom zoo sim lawv cov kev pabcuam PCB yog tias koj xav tau.
Khoom siv
Cov Nqi Khoom ntawm GitHub (nyem qhov txuas kom tau txais cov ncauj lus kom ntxaws BOM rau txoj haujlwm)
Cov Cuab Yeej thiab Khoom Siv
- Cua Cua Rework Chaw Nres Tsheb
- Cov iav tsom iav / Hluav Taws Xob Hluav Taws Xob
- Soldering Hlau
- Solder Paste thiab Solder
- Tweezers
- USBasp
Kauj Ruam 1: Tau Txais Koj Cov PCBs Tsim
Thawj kauj ruam hauv kev tsim cov keychain tivthaiv tester tau txais cov PCBs tsim rau nws.
Koj tuaj yeem pom Gerber Cov Ntaub Ntawv rau PCB tsim hauv qab cov ntaub ntawv lossis ntawm txoj haujlwm GitHub repo. Kuv siv PCBWay Qhov Kev Pabcuam Ua Haujlwm kom tau txais kuv cov laug cam tsim. Lawv muab cov laug cam zoo rau tus nqi qis thiab pheej yig. Lawv kuj tseem muaj ntau yam kev tiv thaiv daim npog ntsej muag xaiv los sim. Kuv tau txais kuv cov laug cam tsim nrog Matte Black solder mask uas ua rau PCBs saib zoo heev.
Xwb, koj tuaj yeem nyem qhov txuas kom xaj PCBs ncaj qha los ntawm PCBWAY. Koj tseem tuaj yeem ntxiv SMD Stencil los ntawm lawv tsuas yog $ 10.
Kauj Ruam 2: Cia Pib Pib …
Cov npe ntawm cov khoom siv hauv ntu khoom siv saum toj no muab cov ncauj lus ntxaws txog cov khoom koj xav tau kom xaj kom pib nrog txheej txheem sib dhos. Cov khoom siv muaj tus lej tsim khoom siv yog li koj tuaj yeem tua cov khoom tsis muaj teeb meem.
Kuv feem ntau pib los ntawm kev siv cov tshuaj tiv thaiv thawj zaug ua ntej los ntawm cov khoom siv hluav taws xob thiab tom qab ntawd txav mus rau cov khoom loj xws li microcontroller, cov nyees khawm, OLED Zaub, thiab lwm yam Nws ua rau lub neej yooj yim dua.
R️ Nco ntsoov Teem MICROCONTROLLER DOT Nrog DOT ntawm PCB (Zaum C6) Ua ntej koj pib muag nws ⚠️
Kauj Ruam 3: Cia Mus Txiv Tsawb
Txhawm rau ntxiv cov txiv tsawb, maj mam tin lub hauv paus ntawm PCB qhov twg txiv tsawb qhov nkag mus thiab xaub hauv lub qhov (socket) raws li qhia. Thaum koj xaub-hauv tso me ntsis ntawm qhov nruab nrab ntawm qhov chaw me me ntawm txiv ntseej hex thiab lub hauv paus. Qhov no yuav ua kom muaj kev sib txuas ruaj khov thiab muab rau koj qhov txiaj ntsig zoo dua thiab raug dua qhov kev xeem.
Kauj ruam 4: Uploading Firmware
Kho vajtse teeb
Siv USBasp programmer txuas nws mus rau ICSP header ntawm lub rooj tsavxwm. Xa tus pinout rau kev sib txuas (Hauv qab ntawm PCB).
Kev Txhim Kho Software
RE️ YUAV TSUM: Koj yuav tsum muaj AVRDUDE teeb tsa hauv koj li kab ke txhawm rau ua raws cov lus qhia hauv qab no kom ua haujlwm.
- Rub tawm cov ntaub ntawv firmware los ntawm GitHub.
- Hauv Terminal/Command Prompt, txav mus rau qhov chaw nyob nrog cov ntaub ntawv saum toj no thiab ua raws cov lus txib hauv qab no-
// Flashing.hex thiab.eep cov ntaub ntawv rau MCU
avrdude -c usbasp -B 20 -p m328p -P usb -U nyem: w:./ TransistorTester.hex: a -U eeprom: w:./ TransistorTester.eep: a

Kauj ruam 5: Calibration
Yog koj tus tester hais tias "Tsis Calibrated"
Koj yuav xav tau ob lub capacitors ib qho nrog qhov muaj txiaj ntsig> 100nF thiab lwm qhov nrog 4-35nF.
- Txhawm rau pib ntsuas, luv peb qhov kev soj ntsuam ua ke.
- Thaum nws hais "Selftest?", Ntev Nias lub pob rau 2 vib nas this.
- Ua raws li cov lus qhia ntawm qhov screen. Thaum hais kom lub capacitor> 100nF. Txuas nws nruab nrab ntawm tus pin 1 thiab 3. Ua raws nws yuav qhia sai sai rau lub capacitor nrog tus nqi nruab nrab ntawm 4nF thiab 35nF. Ntsaws rau hauv.
- Tus Tester yuav hais sai li "Test Completed".
Koj tau ua tiav ntsuas ntsuas?
Kauj ruam 6: HALLELUJAH! Koj Ua Tau Ib: D
TAA DAWB !! Koj tsuas yog ua koj tus kheej ua tus ntsuas ntsuas qhov ntsuas ntsuas?
Hwj chim lub tester ntawm USB-C? Thiab ntsaws rau hauv? cov khoom koj xav sim.
Cheers?
Koj tseem tuaj yeem yuav cov khoom sib dhos ua ke los ntawm kuv Tindie Shop
