[UMartin] uthumele lo mbuzo kumgca wesikhumbuzo kunye nefoto ephambili, waza wathetha into elungileyo. Uninzi lweebhodi zophuhliso kunye novavanyo zinemigca emininzi yeepini, ezihlala zikhululekile kwiphakheji-ukudityaniswa kwepakeji kushiyelwa umsebenzisi. Ukuze silumke, sidla ngokuyila iibhodi zeprototype ezineentloko ezininzi zokulungisa iimpazamo nokuvavanya. Kodwa njengoko [uMartin] esikhumbuzile, kukho ezinye iindlela ezingasetyenziswa endaweni yokuwelda.
Ukuba ufuna ukufaka ibhodi yesekethe kwenye ikhadi (umzekelo, faka isiciko kwiRaspberry Pi), ezi ndlela aziyi kunceda. Nangona kunjalo, xa ufuna nje ukufumana ezinye iimpawu ze-serial port okanye ukufumanisa ezinye iimpawu zedijithali ze-I/O, ukufaka ezinye zezi kliphu kwibhokisi yezixhobo kunokukongela ixesha kunye neengxaki zokudibanisa amalungu. Ngaba unazo naziphi na iindlela zokwenza ii-headers ze-soldering zibe lula, okanye uziphephe ngokupheleleyo? Nceda usazise kwizimvo ezingezantsi.
Andicingi ukuba ndinazo iintambo ze-pin header kwaye ndisoloko ndizidibanisa iingcingo ngqo kwimingxunya apho kufuneka ziye khona ii-pin header.
Ndikhumbula ndisebenza kwibhodi yesekethe ene-crimp backplane connector kudala (ikwathembeke kakhulu), ngoko ke ndakhangela imawusi ngokukhawuleza, ungafumana nezihlanganisi ze-crimp, umzekelo i-Amphenol BPH7B10H00LF ineendlela ezili-10, imiqolo emi-2, i-pitch ye-0.1 intshi.
Ukuba kukho umntu onendlela entsha eqhelekileyo nengabizi kakhulu yokunxibelelana nazo zonke ii-IOs kunye neempawu ezifunekayo kwibhodi yovavanyo...ndiyakuvuma oko. Kodwa ngoku, kwii-microcontrollers, isixhumi se-0.1-intshi silungele lo matshini. Kakade ke, ukuba awusebenzisi kakhulu izixhobo (ezifana neebhodi ze-wifi okanye ze-Ethernet), awudingi okuninzi. Mhlawumbi sisixhumi esiqhelekileyo okanye ibhasi ye-I2C, njl.njl.?
Ewe, yiloo nto ndicinga ngayo...Ndiyazithanda izihloko ze-intshi eziyi-0.1. Kulula kakhulu ukuzisongelisa, kulula ukuzibeka iilead zovavanyo lwe-ic clip. Zinkulu ngokwaneleyo ukuba ungabona into oyenzayo, ungasebenzisa i-Sharp okanye i-nail polish ukuphawula iiphini ezinomdla ebhodini okanye kwisiseko seplastiki. Ungazibeka kwi-breadboard. Sebenzisa nje iteknoloji elula kakhulu kwiinjongo zam.
Isizathu sokuba ndingayisebenzisi le sihloko kukuba xa kufuneka ndiyibeke kwibhokisi encinci ekupheleni, kule meko, ndinethamsanqa (ymmv) lokusebenzisa i-ic clip lead ngqo kumngxuma we-pcb. Kodwa eneneni, xa ndenza i-prototyping, andikhathali kakhulu ngobukhulu, kwaye ukuba ndigqibela ndisebenzisa i-prototype electronics kwibhokisi yokugqibela, ngokuqinisekileyo andiyi kuyinqumla i-test line ukuze ndonge indawo.
Izizathu: ixabiso, indawo. 1) Kwiimveliso zorhwebo, ixabiso lokufakelwa kunye nokuzifaka liyanda. Oku kwenza imveliso yakho ingathandwa xa kuthelekiswa neemveliso ezixabisa ngaphantsi ngeesenti ezili-10. 2) Ndenze uyilo oluninzi, kwaye isixhumi se-intshi eziyi-0.1 sokulungisa iimpazamo/ukucwangcisa siya kuthatha indawo engaphezulu (ivolumu) kunezinye iisekethe!
Nangona oku kusenokuba yinyani, kukho izakhono ezisisiseko ezinxulumene nezinto ozithandayo...I-elektroniki *isoloko* yinto oyithandayo, nokuba ngumsebenzi ofuna izakhono ezithile, kwaye ukusetyenziswa kwe-solder kwiisekethe kusoloko kuphambili. Ukukwazi ukwenza unxibelelwano bekusoloko kuphambili.
Ngoku *sele* kukho izinto ezifana nee-adapters ze-winding kunye ne-screw connector ukunciphisa okanye ukuphelisa isidingo sokutshixa, kodwa ezi zibiza indawo, kwaye ngamanye amaxesha kusafuneka ukutshixa okanye ukuhlawula ngaphezulu ngokukhetha ii-screw terminals. Ukuba oku kuyakukhathaza, ndiyaxolisa, kodwa le yinto eyenzekayo ebomini, kwaye "iimbono ezahlukeneyo" aziqhelekanga ukuba ungazilinganisi ngezinye iindlela. Mhlawumbi imbono "enqwenelekayo" ngakumbi kukuqonda ukuba abanye abantu abayi kukwazi ukwenza izinto ezithile ngaphandle kwezakhono ezithile.
Ndicinga ukuba andiqondi ukuba kubuhlungu kangakanani ukutshixa ii-pin headers. Ndingawugqiba kakuhle umqolo we-40-pin ngaphantsi komzuzu omnye. Mhlawumbi kungenxa yokuba ndikwenza rhoqo? Ndiyabona ukuba oku kuluncedo kwizinto ezikhawulezayo ezihlala zikwiindawo ezixineneyo.
Ngamanye amaxesha ukuvavanya nokwenza iiprototyping ngaphandle kwe-solder yingcinga elungileyo kwaye kulula ukuyitshintsha. Ndisandula uku-odola iindidi ezininzi ze-clothespin kwi-AliExpress. Kwaye uyazi ukuba ukuba usebenzisa isihloko sokugqibela, loo bhodi iya kuqhushumba.
Le yindlela endiyithandayo yokutshixa isixhumi esineephini ezingama-40 (inqaku lebhonasi kwi-sequence yokugqibela ethi "sponge must die"). https://www.youtube.com/watch?v=i9pd9sY0Tjg
Indlela umhlobo wakho uRalph enza ngayo izinto ixhaphakile kakhulu. Njengoko abanye besitsho, kunzima ukoyisa iintloko zepitch eziyi-0.1 intshi. I-2mm (okwangoku) imbi...
Ibhodi eneembobo iya kugcina iiphini zilungelelene kwaye zisendaweni yazo ngexesha lokutywina. Ingakumbi ukuba usebenzisa izihloko ezininzi ngokulandelelana.
Ukuba bendingayidibanisa intloko yesilisa, bendingayidibanisa nentloko yesilisa ngexesha lokuyidibanisa ukuze izikhonkwane zihlale zithe tye xa zishushu.
Lo ngumkhwa omhle phantse kuyo nayiphi na uhlobo lwesixhumi. Ndisebenzisa yonke into ukusuka kwii-headers ukuya kwizixhumi ezinkulu zamandla ze-XT90. Akukho nto imbi ngaphezu kokulahla izixhumi ezinyibilikisiweyo kancinci ubomi bonke besixhobo.
Ndiyithanda kakhulu indlela iTagConnect ebonakala ngayo, kodwa ndisoloko ndivakalelwa kukuba ixabiso liphezulu kancinci, ngoko ke ndenze olu yilo ngexabiso elincinci: https://hackaday.io/project/171391-tagless-programmer
> […] Iikliphu zepini zepogo ezingabizi kakhulu. Ungazithenga ezi mveliso kumsasazi wakho we-elektroniki waseAsia owuthandayo ngemali engaphantsi kwe-$10.
Enyanisweni, zifana needola ezingama-35. Ndiyaqonda, azizidola ezili-10, kodwa sisixhobo esinokusetyenziswa kwakhona. Ukongeza, i-OG iya kuba nokuthenjwa ngakumbi kwaye ixhaswe. Baza kukunika uphawu abaluhlolisise ngokufanelekileyo.

Iipini ze-pogo ezingabizi kakhulu zinqumliwe kumfanekiso wokuqala kwaye zisebenzisa isithuba se-pin esingu-0.1" sesixhumi esithe ngqo. Azisebenzisi sithuba sikhethekileyo okanye zifuna inkxaso ngokwenene. Ukuba awunaso isithuba sesixhumi esingu-0.1", iTagConnect inokuba luncedo.
Kubonakala ngathi zimbalwa kakhulu iindlela zokudibanisa ii-header pads, kodwa ukuba sicinga ukuba asikaze sidibanise ii-headers, kodwa sisoloko sisebenzisa ii-pogo pins, njl.njl., yeyiphi idizayini elungileyo "yee-connector pads"? Mhlawumbi yimo enamazinyo, evumela ukuba imodyuli ixutywe kwibhodi yabathwali, njl.njl.?
Okundimangalisayo kukuba, abanye abantu bayakuchasa ukusetyenziswa kwayo ngezizathu ezingaqhelekanga, kuquka yonke imizamo "eyongezelelweyo" yokubeka ibhodi yesekethe usebenzisa olu yilo (khetha unyawo olunye endaweni yolunye), nto leyo endenza ndizive ndingaqhelekanga. Ilungu leforam edumileyo laphikisana ngobuyatha bakhe ngezi mpuku zeenyawo, waza wavalwa inyanga yonke. Makabongwe intliziyo yakhe.
Ewe, ndingazidibanisa izihlanganisi eziqhelekileyo ze-intshi eziyi-0.1, kodwa kulula kakhulu ukusebenzisa iinyawo zokutshixa. Ndikhumbula umphathi wam ekhuthaza ukuba kusebenze ngobuchule endaweni yokusebenza nzima.
Le yingcinga entle, kwaye ii-pins zingachukumisa zonke ezi pins-ukuze ukwazi ukufaka isixhumi esikhawulezayo kwiprogram okanye ekulungiseni iimpazamo uze usisuse ngaphandle kokusongelwa.
Ndisandula ukuthenga ikhithi ye-PCBite yokuphonononga amanqaku ovavanyo njengendlela eyahlukileyo yokutshixa iileya ezibhabhayo kwibhodi nganye yesekethe. Ngokusisiseko yiseti yeepini ze-pogo kwi-gooseneck. Azibizi kakhulu, kwaye izibambo zeprobe zikhulu kakhulu, nto leyo eyenza kube nzima ukubona imiqondiso esondeleleneyo, kodwa ngaphandle koko iluncedo kakhulu. Ikwabukeka intle kakhulu!
Kwiprojekthi eneebhodi ezininzi zeprototype, ndoneliseke kakhulu yi-http://protofusion.org/wordpress/2013/05/open-hardware-pogo-pin-programmer/. Nangona kunjalo, ukuba uphosa ibhodi ye-pogo, uza kubuyela kwindawo yokuqala.
Bendisoloko ndisebenzisa iTag-Connect kuzo zonke iibhodi zam kangangeminyaka emininzi, ngaphandle koyilo. Ixabiso elifanelekileyo.
Enye indlela 1. IiPogopins, zibiza kakhulu. Kwaye, ukuba ufuna ukwenza isixhobo sovavanyo kwibhodi yakho yesekethe, nceda ukope uyilo lwebhodi yesekethe uze wongeze umngxuma we-1mm naphi na apho ufuna ukuvavanya khona iindawo, uze ufake iipogopins kwezi mingxuma uze ufake intambo kwiConnector efanelekileyo.
Enye indlela eluncedo kakhulu yesi-2: Ukuba unenani elincinci leepini, ukuya kuthi ga kwiipini ezi-4 zilandelelana, okanye iipini ezi-2×3, bhoboza imingxunya yee-connectors ze-2 mm. Intloko yesilisa eqhelekileyo ye-0.1 intshi iya kufanelana kakuhle nomngxuma, ngenxa yepini ethe tyaba kancinci yokugcina kakuhle.
Mhlawumbi ungazama isixhumi sePogo pin esinemigca emibini. Ndiyayithanda le nto. https://www.pogo-pins.com/products/629.html Ndiyathemba ukuba ndiza kukunceda. Andy
