2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:28

ESP8266 pawg thawj coj txhim kho yog qhov zoo mus rau pawg thawj coj rau koj li IOT cov haujlwm, tab sis nthuav tawm cov teeb meem yog tias lawv siv roj teeb. Nws tau sau tseg zoo li cas ntau yam ESP8266 kev txhim kho cov laug cam tsis muaj hwj chim ua tau zoo (ntawm no thiab ntawm no). Pawg Witty Development Board yeej dhau qee qhov teeb meem los ntawm kev sib cais USB rau TTL (programmer interface) tab sis tsis muaj kev tiv thaiv zoo ib yam ntawm D1 Mini Qhov no D1M BLOCK tawg ESP12 nrog Wemos D1 Mini tus ntawv cog lus, thiab yog tsim nrog tsis muaj kev tswj hwm lossis MCP1700 tus tswj hwm.

Qhov no yog kev tsim vaj tsev fiddly thiab zoo rau qhov pov thawj-ntawm-lub tswv yim lossis cov lej xav tau tsawg; Kuv yuav taug qab nrog PCB yooj yim dua.

NCO TSEG: rau qhov tsis tsim kev cai:

1. ESP12 kev siv hluav taws xob tau tshaj tawm li 3.0 ~ 3.6V
2. Qee cov neeg tshaj tawm ua tiav kev ua haujlwm tsis raug cai ntawm 3.7V LiPo roj teeb (3.3 txog 4.2V)
3. Saib ntawm daim duab kos tam sim no saum toj no los ntawm https://forum.makehackvoid.com/t/esp8266-operatin… koj yuav pom muaj kev lag luam cuav tsis siv tus tswj hwm thaum pw tsaug zog ua haujlwm.
4. Kev tsim tsis raug cai tau muab, tab sis kuv hais kom tsis txhob siv pw tsaug zog thiab paub txog qhov ntsuas hluav taws xob tau thov rau 3V3.

Keeb Kwm:

• 2018-02-15-Thawj Zaug Tso
• 2018-02-19-rub tawm ntxiv rau I2C (D1/D2)
• 2018-02-22-pulldown hloov los ntawm IO2 mus rau IO15, 2mm suab txiv neej lub taub hau siv siv cov hlau tsis xeb.

NCO TSEG: Siv qhov ntsuas ntsuas txuas mus ntxiv ntawm lub ntsuas cua kom ntseeg tau tias cov xov hlau tsis txuas txhua lub sijhawm.

Kauj Ruam 3: Siv Lub Taub Hau Taub Hau (siv SOCKET JIG)

Muaj cov vis dis aus saum toj no uas sau los ntawm txheej txheem txheej txheem rau SOCKET JIG.

1. Pub cov kab taub hau hla hauv qab ntawm lub rooj tsavxwm (TX sab laug-sab laug rau sab saum toj).
2. Pub jig hla lub taub hau yas thiab qib ob sab.
3. Tig jig thiab sib dhos dua thiab nias lub taub hau ncaj qha mus rau qhov tiaj tiaj.
4. Nias lub rooj tsavxwm nqes mus rau lub jig.
5. Solder 4 lub kaum tus pin uas siv cov laug me me (tsuas yog ua ntu zus ntawm tus pin).
6. Reheat thiab rov ua haujlwm pawg thawj coj/tus pin yog xav tau (pawg thawj coj lossis tus pin tsis sib dhos lossis cov kav dej).
7. Solder tus so ntawm tus pin.

Kauj Ruam 4: Gluing Cheebtsam rau hauv paus

Tsis suav nrog hauv cov vis dis aus, tab sis pom zoo: muab lub dob loj ntawm cov kua nplaum kub tso rau hauv lub hauv paus khoob ua ntej tso lub rooj tsav xwm sai thiab ua kom sib haum - qhov no yuav tsim cov yuam sij rau ntawm ob sab ntawm lub rooj tsavxwm. Thov ua kom qhuav hauv qhov tso cov ntaub thaiv npog rau hauv qab. Yog tias cov gluing tsis raug, koj yuav tsum tau ua qee qhov teeb pom kev ntawm ntug ntawm PCB.

1. Nrog lub hauv paus casing hauv qab qhov taw qhia taw qhia, tso cov khoom sib dhos ua ke yas lub taub hau hla lub qhov hauv qab; tus (TX tus pin yuav nyob ntawm sab nrog lub hauv paus zawj).
2. Muab cov kua nplaum kub kub tso rau hauv qab lub hauv paus nrog cov yas yas tso los ntawm nws cov zawj.
3. Zaum cov kua nplaum kub kub rau ntawm qhov chaw tiaj tiaj thiab ua tib zoo thawb lub PCB kom txog thaum cov yas taub hau tsoo saum npoo; qhov no yuav tsum muaj cov pins muab tso kom raug.
4. Thaum siv cov kua nplaum kub ua kom nws nyob deb ntawm lub taub hau thiab tsawg kawg 2mm los ntawm qhov chaw uas lub hau yuav nyob.
5. Siv cov kua nplaum rau txhua 4 lub ces kaum ntawm PCB kom ntseeg tau tias muaj kev sib cuag nrog cov phab ntsa hauv paus; pub nkag mus rau ob sab ntawm PCB yog tias ua tau.

Kauj Ruam 5: Kaw lub hau rau lub hauv paus

1. Xyuas kom cov pins tsis muaj kua nplaum thiab sab saum toj 2mm ntawm lub hauv paus tsis muaj kua nplaum kub.
2. Ua ntej haum lub hau (qhuav qhuav) ua kom ntseeg tau tias tsis muaj cov khoom cuav luam tawm.
3. Ua tib zoo ceev faj thaum siv Cyanoachrylate nplaum.
4. Thov Cyanoachrylate mus rau hauv qab cov ces kaum ntawm lub hau kom ntseeg tau tias muaj kev tiv thaiv ntawm ib sab toj ib sab.
5. Ceev nrooj haum lub hau rau lub hauv paus; clamping kaw lub ces kaum yog ua tau.
6. Tom qab lub hau qhuav qhuav khoov txhua tus pin yog li nws yog qhov tseem ceeb hauv qhov khoob yog tias tsim nyog.

Kauj Ruam 6: Ntxiv Cov Ntawv Adhesive

1. Thov pinout daim ntawv lo rau hauv qab ntawm lub hauv paus, nrog RST tus pin ntawm ib sab nrog zawj.
2. Siv daim ntawv cim tus cim rau sab uas tsis yog qhov nqaim, nrog cov pins tsis muaj dab tsi yog sab saum toj ntawm daim ntawv lo.
3. Nias cov ntawv sau kom ruaj khov, nrog cov cuab yeej tiaj tus yog xav tau.
