[Martin] akatumira mubvunzo uyu kumutsara wekuyeuchidza pamwe chete nemufananidzo mukuru, uye akataura pfungwa yakanaka. Mabhodhi mazhinji ekugadzira nekuongorora ane mitsara yakawanda yemapini, ayo anowanzo sunungurwa mupakeji - soldering inosiyirwa kumushandisi. Kuti tichenjerere, tinowanzo gadzira mabhodhi emuenzaniso ane misoro yakawanda yekugadzirisa nekugadzirisa. Asi sezvatakayeuchidzwa na[Martin], kune dzimwe nzira dzekugadzirisa pane welding.
Kana uchida kuisa bhodhi redunhu mune rimwe kadhi (semuenzaniso, isa chivharo muRaspberry Pi), matekiniki aya haabatsiri. Zvisinei, kana uchingoda kuwana mamwe masaini echiteshi cheserial kana kuona mamwe masaini eI/O edhijitari, kuisa mamwe ema clips aya mubhokisi rematurusi kunogona kukubatsira kuchengetedza nguva nematambudziko ekubatanidza majoini. Une manomano ekuita kuti maheaders ekusoldering ave nyore here, kana kutoadzivisa zvachose? Ndokumbirawo utizivise mumashoko ari pazasi.
Handifungi kuti ndine tambo dze pin header uye ndinogara ndichibatanidza waya dzacho zvakananga mumaburi anofanirwa kuenda ne pin headers.
Ndinoyeuka ndichishanda pabhodhi redunhu rine crimp backplane connector kare kare (yakavimbikawo), saka ndakakurumidza kutsvaga mbeva, unogona zvakare kuwana crimp connectors, semuenzaniso Amphenol BPH7B10H00LF ine 10-way ine 2 rows ne 0.1 inch pitch.
Kana paine munhu ane nzira itsva yakajairwa yekubatanidza kune ese maIO uye masaini anodiwa pabhodhi rekuongorora...ndinoda kuzvigamuchira. Asi ikozvino, kune ma microcontrollers, chinobatanidza che 0.1-inch ndicho chakanakira uyu mugadziri wezvinhu. Ehe, kana usingashandise hardware zvakanyanya (senge wifi kana Ethernet boards), haudi zvakawanda. Pamwe ingori chinobatanidza chakajairika kana bhazi re I2C, nezvimwewo?
Ehe, ndizvo zvandinofunga...Ndinoda 0.1 inch titles. Zviri nyore kwazvo kusonesa, zviri nyore kuisa ic clip test leads. Yakakura zvakakwana zvekuti unogona kuona zvauri kuita, unogona kushandisa Sharp kana nail polish kuratidza mapini anonakidza pabhodhi kana pachigadziko chepurasitiki. Unogona kuaisa pabhodhi. Ingoshandisa tekinoroji iri nyore kwazvo pazvinangwa zvangu.
Chikonzero chega chandinosiya chinyorwa ndechekuti kana ndichida kuchiisa mubhokisi diki kumagumo, muchiitiko ichi, ndine rombo rakanaka (ymmv) kushandisa ic clip lead zvakananga paburi repcb. Asi kutaura chokwadi, pandinoita prototyping, handiwanzo funga nezvehukuru, uye kana ndikazopedzisira ndashandisa prototype electronics mubhokisi rekupedzisira, handizodi kucheka mutsetse wekuyedza kuti ndichengetedze nzvimbo.
Zvikonzero: mutengo, nzvimbo. 1) Pazvigadzirwa zvekutengeserana, mutengo wezvigadziko uye kuzviisa zvinowedzera. Izvi zvinoita kuti chigadzirwa chako chisafarirwe kana tichienzanisa nezvigadzirwa zvinodhura masendi gumi pasi. 2) Ndakagadzira madhizaini akawanda, uye chinongedzo che 0.1 inch chekugadzirisa/kuronga chinotora nzvimbo yakawanda (vhoriyamu) kupfuura zvimwe zvese zvedunhu!
Kunyangwe izvi zvingave zvechokwadi, kune hunyanzvi hwekutanga hune chekuita nezvinhu zvinovaraidza...Magetsi *nguva dzose* chinhu chinovaraidza, kunyangwe basa rinoda hunyanzvi hwakati, uye kushandiswa kwesolder kumasekete ndiko Kugona kugadzira kubatanidza kwagara kuri pamberi.
Iye zvino *kwatova* nezvinhu zvakaita sema winding ne screw connector adapters ekuderedza kana kubvisa kudiwa kwekusungirirwa, asi izvi zvinodhura nzvimbo, uye dzimwe nguva zvichiri kudiwa kusungirirwa kana kubhadhara mari yakawanda pakusarudza ma screw terminals. Kana izvi zvichikunetsa, ndine urombo, asi ichi ndicho chokwadi chehupenyu, uye "maonero akasiyana" haawanzoitiki kana usingaafungidzire nedzimwe nzira. Pamwe maonero "anodiwa" ndeekuziva kuti vamwe vanhu havazokwanisi kuita zvimwe zvinhu vasina hunyanzvi hwakati.
Ndinofunga handinyatsonzwisisa kuti zvinorwadza sei kusundira pamusoro pemapini. Ndinogona kupedzisa mutsara wemapini makumi mana zvakanaka mumaminitsi asingasviki 1. Pamwe imhaka yekuti ndinowanzozviita? Ndinoona kuti izvi zvinobatsira pazvinhu zvinopenya zvinowanzova munzvimbo dzisina ruzha rwakanyanya.
Dzimwe nguva kuyedza nekugadzira ma prototyping pasina solder ipfungwa yakanaka uye inochinjika. Ndichangobva kuraira mhando dzakasiyana dzezvipfeko paAliExpress. Uye unoziva kuti kana ukashandisa zita rekupedzisira, bhodhi iroro richaputika.
Iyi ndiyo nzira yandinofarira yekusonesa chinobatanidza chine mapini makumi mana (chinhu chinobatsira zvikuru pakuita kuti "sponge must die" iite sequence yekupedzisira). https://www.youtube.com/watch?v=i9pd9sY0Tjg
Maitiro eshamwari yako Ralph ekuita zvinhu akajairika. Sezvakataurwa nevamwe, misoro ye 0.1-inch yakaoma kukunda. Iyo 2mm (pari zvino) yakaipa...
Bhodhi rakaboorwa rinoita kuti mapini arambe akarongeka uye ari panzvimbo yawo panguva yekunamira. Kunyanya kana ukashandisa misoro yakawanda yakatevedzana.
ndakachenjera! Dai ndaizobatanidza musoro wemurume, ndaizobatanidza nemusoro wemukadzi panguva yekusanganisa kuti mapini arambe akatwasuka kana achinge apiswa.
Iyi itsika yakanaka kune chero rudzi rwechinobatanidza. Ndinoshandisa zvese kubva kumaheader kusvika kumapower connectors makuru eXT90. Hapana chakaipa kupfuura kurasa zvinobatanidza zvakanyunguduka zvishoma kwehupenyu hwese hwechishandiso.
Ndinofarira zvikuru TagConnect, asi ndinogara ndichifunga kuti mutengo wayo wakakwira zvishoma, saka ndakagadzira dhizaini iyi nechikamu chidiki chemutengo: https://hackaday.io/project/171391-tagless-programmer
> […] Zvipikiri zvepogo zvakachipa. Unogona kutenga zvigadzirwa izvi kubva kumutengesi wezvigadzirwa zvemagetsi wekuAsia waunofarira nemutengo usingasviki $10.
Zvechokwadi, dzakaita semadhora makumi matatu nemashanu. Ndinozvinzwisisa, haisi madhora gumi, asi chishandiso chinogona kushandiswazve. Pamusoro pezvo, OG ichave yakavimbika uye inotsigirwa. Vachakupa chiratidzo chavakanyatsoongorora.

Mapini epogo akachipa anochekwa pamufananidzo wekutanga uye anoshandisa 0.1" pin spacing ye linear connector. Haashandise footprint yakasiyana kana kuti anoda rutsigiro. Kana usina nzvimbo ye 0.1" connector, TagConnect inogona kubatsira.
Zvinoita sekuti magadzirirwo mashoma ekubatanidza ma header pads, asi kana tikafunga kuti hatimbofi takabatanidza ma header, asi tichishandisa pogo pins, nezvimwewo, ndeipi dhizaini yakanaka ye "connector pads"? Pamwe chimiro chine mazino, icho chichiri kubvumira module kuti isanganiswe kune carrier board, nezvimwewo?
Zvakandishamisa kuti vamwe vanhu vanoramba kuishandisa nekuda kwezvikonzero zvisina musoro, kusanganisira kuedza kwese "kwekuwedzera" kuisa bhodhi redunhu uchishandisa dhizaini iyi (sarudza tsoka imwe panzvimbo peimwe), izvo zvinoita kuti ndinzwe sekunge ndisinganzwisisike. Nhengo yeforamu yakakurumbira yakakakavadzana nezveupenzi hwake nekuda kwemakonzo aya etsoka, uye akarambidzwa kwemwedzi wese. Ropafadzwai moyo wake
Ehe, ndinokwanisa kusona zvibatanidza zve 0.1 inch, asi zviri nyore kushandisa tsoka dzinokiya. Zvinoita sekuti ndinoyeuka mukuru wangu achikurudzira kuti tishande nekuchenjera pane kushanda nesimba.
Iri izano rakanaka, uye mapini anogona kubata mapini ese aya - saka unogona kuisa chinongedzo chinokurumidza mukugadzira mapurogiramu kana kugadzirisa matambudziko wobva wabvisa pasina kusungirira.
Ndichangobva kutenga PCBite kit yekuyedza nzvimbo dzekuyedza senzira yekutsiva nhare dzinobhururuka dzebhodhi rega rega. Chaizvoizvo ipogo pini dziri pamutsipa wegooseneck. Hadzina kudhura zvakanyanya, uye zvibato zveprobe zvakakura kwazvo, izvo zvinoita kuti zviome kuona zviratidzo zviri pedyo, asi zvikasadaro zvinobatsira chaizvo. Inotaridzika zvakanaka kwazvo!
Papurojekiti ine mabhodhi akawanda emuenzaniso, ndagutsikana zvikuru ne http://protofusion.org/wordpress/2013/05/open-hardware-pogo-pin-programmer/. Zvisinei, kana ukaisa pogo board panzvimbo yayo, uchadzokera panzvimbo yekutanga.
Ndanga ndichishandisa Tag-Connect pamabhodhi angu ese kwemakore mazhinji, zvisinei nekwakagadzirwa. Mari yacho inokosha.
Imwe nzira 1. Pogopins, yakachipa zvikuru. Uye, kana uchida kugadzira chinhu chekuyedza chebhodhi rako redunhu, ndapota tevedzera dhizaini yebhodhi redunhu wobva wawedzera gomba re1mm pese paunoda kuyedza mapoinzi, wobva waisa mapini epogo pamaburi aya woisa waya panzira yacho kuConnector yakakodzera.
Imwe nzira inobatsira zvikuru 2: Kana uine mapini mashoma, anosvika mapini mana akatevedzana, kana 2×3, rovera maburi ezvinobatanidza zve 2 mm. Musoro wemurume we 0.1 inch wakajairika unoenderana neburi racho zvakanaka, nekuda kwepini yakatetepa zvishoma kuti irambe ichibata zvakanaka.
Pamwe unogona kuedza chinongedzo chePogo pin chine mitsara miviri. Ida izvi. https://www.pogo-pins.com/products/629.html Ndinovimba kukubatsira. Andy
Nekushandisa webhusaiti yedu nemasevhisi, unobvumirana zvakajeka kuti makuki edu ekushanda, mashandiro uye ekushambadzira aiswe. dzidza zvakawanda
