2.3 Izikhonkwane zokubopha
I-ESP32 inamaphini amahlanu okubopha, angabonwa kuSahluko 6 Schematics:
- I-MTDI
- I-GPIO0
- I-GPIO2
- I-MTDO
- I-GPIO5
Isofthiwe ingafunda amanani alawa mabhithi amahlanu kurejista ”GPIO_STRAPPING”. Ngesikhathi sokukhishwa kokusetha kabusha isistimu ye-chip (ukusetha kabusha amandla, ukusetha kabusha i-watchdog ye-RTC, nokusetha kabusha i-brownout), ama-latches wezikhonkwane zokubopha sample voltage ileveli njengamabhithi okubopha okuthi "0" noma "1", bese ubamba lezi zingcezu kuze kube yilapho i-chip yehliswa amandla noma ivaleka. Izingcezu zokubopha zimisa imodi yokuqalisa yedivayisi, ivolumu yokusebenzatage ye-VDD_SDIO, nezinye izilungiselelo zokuqala zesistimu.
Iphinikhodi ngayinye yokubopha ixhunywe ekudonseleni phezulu/kwehle kwangaphakathi ngesikhathi sokusetha kabusha i-chip. Ngakho-ke, uma iphinikhodi yokubopha ingaxhunyiwe noma isekethe yangaphandle exhunyiwe inamandla amakhulu, ukudonsela phezulu/ukudonsa okubuthakathaka kwangaphakathi kuzocacisa ileveli yokufaka ezenzakalelayo yezikhonkwane zokubopha.
Ukushintsha amanani ebhithi yokubopha, abasebenzisi bangasebenzisa ukumelana kwangaphandle kokudonsela phansi/ukudonsa, noma basebenzise ama-GPIO osokhaya we-MCU ukuze balawule ivolumu.tage ileveli yalawa maphini uma usebenzisa i-ESP32. Ngemuva kokukhishwa kokusetha kabusha, izikhonkwane zokubopha zisebenza njengezikhonkwane ezivamile. Bheka kuThebula 4 ukuze uthole ukulungiselelwa okuningiliziwe kwemodi yokuqalisa ngokubopha amaphini.

OEM Isiqondiso
- Imithetho ye-FCC esebenzayo
Le mojula inikezwe Ukuvunyelwa Kwemodyuli Eyodwa. Ithobelana nezidingo ze-FCC ingxenye 15C, imithetho yesigaba 15.247. - Izimo ezithile zokusebenza zokusebenza
Le mojula ingasetshenziswa kumadivayisi e-RF. I-voltage kumojula ngokwegama elithi 3. 0V-3.6 V DC. Izinga lokushisa elisebenzayo le-ambient ye-module ngu-40 kuya ku-85 degrees C. - Izinqubo zemojula ezinomkhawulo
N/A - Landelela ukwakheka kwe-antenna
N/A - Ukucatshangelwa kokuchayeka kwe-RF
Okokusebenza kuthobelana nemikhawulo yokuchayeka emisebeni ye-FCC ebekwe endaweni engalawuleki. Lo mshini kufanele ufakwe futhi usebenze ngebanga elincane elingama-20cm phakathi kwe-radiator nomzimba wakho. Uma okokusebenza kwakhelwe kumsingathi ukuze kusetshenziswe okuphathekayo, kungase kudingeke ukuhlolwa okwengeziwe kokuchayeka kwe-RF njengoba kucaciswe ngu-2.1093. - I-Antenna
Uhlobo lwe-antenna: I-PIFA antenna ene-IPEX isixhumi; Ukuzuza okuphezulu: 4dBi - Ilebula nolwazi lokuhambisana
Ilebula yangaphandle yomkhiqizo wokugcina we-OEM ingasebenzisa amagama anjengalawa alandelayo:
“Iqukethe i-FCC ID: 2AC7Z-ESPWROOM32UE” kanye
“Iqukethe i-IC: 21098-ESPWROOMUE” - Ulwazi lwamamodi okuhlola kanye nezidingo zokuhlola ezengeziwe
a) Isidlulisi semojuli sihlolwe ngokugcwele ngumnikezeli wemojuli enanini elidingekayo lamashaneli, izinhlobo zokuguquguquka, nezindlela, akufanele kudingeke ukuthi isifaki sosokhaya sihlole kabusha zonke izindlela noma izilungiselelo ezitholakalayo zokusakaza. Kunconywa ukuthi umkhiqizi womkhiqizo osingethe, afake isidlulisi semojuli, futhi enze izilinganiso zophenyo ukuze aqinisekise ukuthi umphumela wesistimu oyinhlanganisela aweqi imikhawulo yokukhishwa okuyinkohliso noma imikhawulo yomkhawulo webhendi (isb, lapho uthi oluhlukile lungase lubangele ukukhishwa okwengeziwe) .
b)Ukuhlola kufanele kuhlole ukukhishwa okungase kwenzeke ngenxa yokuhlangana kwezisi ezikhishwayo nezinye izithumeli, izifunda zedijithali, noma ngenxa yezakhiwo ezibonakalayo zomkhiqizo wokusingatha (indawo evalekile). Lolu phenyo lubaluleke kakhulu lapho kuhlanganisa ama-modular transmitter amaningi lapho ukuqinisekiswa kusekelwe ekuhloleni ngayinye yazo ekucushweni okuzimele. Kubalulekile ukuqaphela ukuthi abakhiqizi bomkhiqizo abasingathile akufanele bacabange ukuthi ngenxa yokuthi isidlulisi semojuli siqinisekisiwe ukuthi abanaso isibopho sokuthobela umkhiqizo wokugcina.
c)Uma uphenyo lukhombisa ukukhathazeka kokuthobela umkhiqizi osokhaya unesibopho sokunciphisa udaba. Imikhiqizo engusokhaya esebenzisa isidluliseli esiyimodulayo ingaphansi kwayo yonke imithetho esebenzayo yomuntu ngamunye kanye nezimo ezijwayelekile zokusebenza kuSigaba 15.5, 15.15, kanye no-15.29 ukuze zingabangeli ukuphazamiseka. Umsebenzisi womkhiqizo wosokhaya uzophoqeleka ukuthi ayeke ukusebenzisa idivayisi kuze kube yilapho ukuphazamiseka sekulungisiwe. - Ukuhlola okwengeziwe, Ingxenye 15 Umshwana Wokuzikhipha Emthwalweni Wengxenye Engaphansi B Umsingathi wokugcina/inhlanganisela yemojuli idinga ukubuyekezwa ngokuqhathanisa nemibandela ye-FCC Ingxenye 15B yamarediyetha angahlosiwe ukuze agunyazwe ngokufanelekile ukuthi asebenze njengedivayisi yedijithali Ingxenye 15. Umhlanganisi wosokhaya ofaka le mojula emkhiqizweni wabo kufanele aqinisekise ukuthi okokugcina
umkhiqizo oyinhlanganisela uthobelana nezidingo ze-FCC ngokuhlolwa kobuchwepheshe noma ukuhlolwa kwemithetho ye-FCC, okuhlanganisa nokusebenza komthumeli, futhi kufanele kubhekisele kumhlahlandlela ku-KDB 996369. Ngemikhiqizo yomsingathi enesidlulisi semodula esiqinisekisiwe, imvamisa yophenyo lwenhlanganisela. isistimu icaciswa ngomthetho OseSigabeni 15.33(a)(1) kuya ku-(a)(3), noma ububanzi obusebenzayo kudivayisi yedijithali, njengoba kuboniswe kuSigaba 15.33(b)(1), kuye ngokuthi yibuphi ububanzi befrikhwensi ephezulu uphenyo Lapho uhlola umkhiqizo wokusingatha, wonke ama-transmitter kufanele asebenze. Ama-transmitter angavulwa ngokusebenzisa izishayeli ezitholakala esidlangalaleni futhi avuliwe, ngakho-ke ama-transmitter ayasebenza. Ezimweni ezithile, kungase kulunge ukusebenzisa ibhokisi lekholi eliqondene nobuchwepheshe (isethi yokuhlola) lapho izisetshenziswa ze-50 noma izishayeli zingatholakali. Lapho kuhlolelwa ukukhishwa okuvela kurediyetha ngokungahlosiwe, isidlulisi sizobekwa kumodi yokwamukela noma imodi yokungenzi lutho, uma kungenzeka. Uma imodi yokwamukela kuphela ingenzeki, umsakazo uzoba yi- passive (okukhethwa kukho) kanye/noma ukuskena okusebenzayo. Kulezi zimo, lokhu kuzodinga ukunika amandla umsebenzi ku-BUS yokuxhumana (okungukuthi, i-PCIe, i-SDIO, i-USB) ukuze kuqinisekiswe ukujikeleza kwerediyetha okungahlosiwe kuvuliwe. Amalabhorethri ahlolayo angase adinge ukwengeza ukuncipha noma izihlungi kuye ngamandla esignali anoma imaphi amabhakhoni asebenzayo (uma kusebenza)
kusukela kumarediyo anikwe amandla. Bheka i-ANSI C63.4, ANSI C63.10, ne-ANSI C63.26 ukuze uthole imininingwane eyengeziwe yokuhlola okuvamile.
Umkhiqizo ohlolwayo usethelwe ekuhlotshaneni komugqa nedivayisi ebambisene, ngokokusetshenziswa okuhlosiwe okujwayelekile komkhiqizo. Ukuze wenze ukuhlolwa kube lula, umkhiqizo ongaphansi kokuhlolwa usethelwe ukudlulisa ngomjikelezo wemisebenzi ephezulu, njengokuthumela file noma ukusakaza okunye okuqukethwe kwemidiya.
Isitatimende se-FCC
Le divayisi ithobela Ingxenye 15 Yemithetho ye-FCC. Ukusebenza kungaphansi kwemibandela emibili elandelayo:
(1) le divayisi ayinakubanga ukuphazamiseka okuyingozi, futhi (2) le divayisi kufanele yamukele noma yikuphi ukuphazamiseka
(2) etholiwe, okuhlanganisa nokuphazanyiswa okungase kubangele ukusebenza okungafunwa.
Isexwayiso se-FCC:
Noma yiziphi izinguquko noma ukuguqulwa okungagunyazwanga ngokucacile yinhlangano enesibopho sokuthobela imithetho kungasusa igunya lomsebenzisi lokusebenzisa okokusebenza.
“Lesi sisetshenziswa sihloliwe futhi kwatholakala ukuthi siyahambisana nemikhawulo yedivayisi yedijithali ye-Class B,
ngokuhambisana nengxenye 15 yeMithetho ye-FCC. Le mikhawulo iklanyelwe ukuvikela ngokunengqondo ekuphazameni okulimazayo ekufakweni kwendawo yokuhlala. Lesi sixhobo sikhiqiza, sisebenzise, futhi singakhipha amandla efrikhwensi yomsakazo futhi, uma ingafakiwe futhi isetshenziswe ngokuhambisana nemiyalelo, ingase ibangele ukuphazamiseka okuyingozi ezokuxhumana ngomsakazo. Nokho, asikho isiqinisekiso sokuthi ukuphazamiseka ngeke kwenzeke ekufakweni okuthile. Uma lesi sisetshenziswa sidala ukuphazamiseka okuyingozi emsakazweni noma kumabonakude, okunganqunywa ngokucisha nokuvula okokusebenza, umsebenzisi uyakhuthazwa ukuthi azame ukulungisa ukuphazamiseka ngesinyathelo esisodwa noma ngaphezulu kwezilandelayo:
- Hlela kabusha noma hambisa uthi olwamukelayo.
- Khulisa ukuhlukana phakathi kwesisetshenziswa nomamukeli.
- Xhuma okokusebenza endaweni yokuphuma kuyisekethe ehlukile kuleyo lapho umamukeli axhumeke khona.
- Xhumana nomthengisi noma uchwepheshe werediyo/TV onolwazi ukuze uthole usizo.”
Isitatimende se-IC:
Le divayisi ithobelana nezinga le-RSS elikhishwe yi-Industrial Canada. Ukusebenza kungaphansi kwezimo ezimbili ezilandelayo: (1) lolu cingo angeke lubangele ukuphazamiseka,
futhi (2) lolu cingo kufanele lwamukele noma yikuphi ukuphazamiseka, okuhlanganisa ukuphazamiseka okungase kubangele ukusebenza okungafuneki kocingo.
