2. Iimeko ezikhethekileyo zokusetyenziswa
   Le modyuli ingasetyenziswa kwizixhobo ze-IoT. Igalelo voltage kwimodyuli yi-3.3V-3.6 V DC. Ubushushu obusebenzayo be-ambient yemodyuli yi-40 °C ~ 65 °C. Kuphela yi-eriyali efakelweyo yePCB evumelekileyo. Nayiphi na enye i-eriyali yangaphandle ayivumelekanga.
3. Iinkqubo zemodyuli ezilinganiselweyo N/A
4. Landela uyilo lwe-eriyaliN/A
5. Iingqwalaselo zokuvezwa kweRF
   Isixhobo sithobela imida yeFCC yokuvezwa ngemitha emiselwe indawo engalawulekiyo. Esi sixhobo kufuneka sifakwe kwaye sisebenze kumgama ongaphantsi kwama-20cm phakathi kweradiyetha kunye nomzimba wakho. Ukuba isixhobo sakhelwe kwinginginya njengosetyenziso oluphathwayo, uvavanyo olongezelelweyo lokuvezwa kweRF lunokufuneka njengoko kuchazwe ngu-2.1093.
6. I-antenna
   Uhlobo lwe-eriyali: I-eriyali ye-PCB Ukuzuza okuphezulu: 3.40dBi I-eriyali ye-Omni ene-IPEX isiqhagamshelanisi Incopho yenzuzo2.33dBi
7. Ilebhile kunye nolwazi lokuthotyelwa
   Ileyibhile yangaphandle kwimveliso yokugqibela ye-OEM inokusebenzisa amagama anjengala alandelayo: “Iqulethe i-ID yemodyuli ye-FCC: 2AC7Z-ESP32WROVERE” okanye “Ine-ID yeFCC: 2AC7Z-ESP32WROVERE.”
8. Ulwazi kwiindlela zovavanyo kunye neemfuno zovavanyo ezongezelelweyo
   a) Isidluliseli semodyuli sivavanywe ngokupheleleyo ngulowo unikwe imodyuli kwinani elifunekayo letshaneli, iintlobo zokumodareyitha, kunye neendlela, akufuneki kube yimfuneko ukuba umfakeli womninimzi aphinde avavanye zonke iindlela zothumelo ezikhoyo okanye useto. Kwenziwa isincomo sokuba umenzi wemveliso engumamkeli, afakele isidluliseli semodyuli, enze imilinganiselo yophando ukuze aqinisekise ukuba inkqubo edityanisiweyo enesiphumo ayigqithi kwimida yokukhutshwayo ebubuxoki okanye imida yomphetho webhendi (umz., apho i-eriyali eyahlukileyo inokubangela ukukhutshwa okongeziweyo).
   b)Uvavanyo kufuneka lujonge izinto ezikhutshwayo ezinokuthi zenzeke ngenxa yokudityaniswa kwezinto ezikhutshwayo nezinye ii-transmitters, i-digital circuitry, okanye iipropathi ezibonakalayo zemveliso yokusingatha (indawo evalelweyo). Olu phando lubaluleke kakhulu xa udibanisa iimodyuli ezininzi zothutho apho uqinisekiso lusekwe ekuvavanyeni ngamnye kubo kuqwalaselo oluzimeleyo. Kubalulekile ukuqaphela ukuba abavelisi beemveliso abasindleka akufuneki bacinge ukuba ngenxa yokuba isidluliseli semodyuli siqinisekisiwe ukuba abanalo naluphi na uxanduva lokuthotyelwa kwemveliso yokugqibela.
   c)Ukuba uphando lubonisa inkxalabo yothotyelo umenzi wemveliso unyanzelekile ukuba awuthobe umba. Iimveliso zokusingatha ezisebenzisa i-modular transmitter zixhomekeke kuyo yonke imigaqo yobugcisa esebenzayo kunye neemeko eziqhelekileyo zokusebenza kumaCandelo 15.5, 15.15, kunye ne-15.29 ukuba angabangela ukuphazamiseka. Umsebenzisi wemveliso yenginginya uya kunyanzeleka ukuba ayeke ukusebenzisa isixhobo de uphazamiseko lulungiswe .
9. Uvavanyo olongezelelweyo, iSahlulo se-15 seCandelwana B isilanduli Umamkeli wokugqibela/udibaniso lwemodyuli kufuneka luvavanywe ngokuchasene nenkqubo yeFCC yeSigaba 15B yeeradiyetha ezingenziwanga ngabom ukuze zigunyaziswe ngokufanelekileyo ukuba zisebenze njengeSahlulo se-15 sesixhobo sedijithali. Umdibanisi ofaka le modyuli kwimveliso yakhe kufuneka aqinisekise ukuba imveliso edibeneyo yokugqibela ihambelana neemfuno zeFCC ngovavanyo lobugcisa okanye uvandlakanyo lwemithetho yeFCC, kubandakanywa nokusebenza komthumeli, kwaye kufuneka ibhekiselele kwisikhokelo kwi-KDB 996369. kunye nesidluliseli semodyuli esiqinisekisiweyo, uluhlu lwamaxesha ophando lwenkqubo ehlanganisiweyo luchazwa ngumgaqo okwiCandelo 15.33(a)(1) ukuya ku (a)(3), okanye uluhlu olusebenzayo kwisixhobo sedijithali, njengoko kubonisiwe kwiCandelo. 15.33(b)(1), nokuba loluphi uluhlu oluphezulu lophando Xa uvavanya imveliso yokusingatha, zonke ii-transmitters kufuneka zisebenze. Iitransmitha zinokuvulwa ngokusebenzisa abaqhubi abakhoyo esidlangalaleni kwaye bavulwe, ngoko ke abathumeli bayasebenza. Kwiimeko ezithile, kunokufaneleka ukusebenzisa ibhokisi yokufowuna ethe ngqo kwiteknoloji (iseti yovavanyo) apho i-accessory 50 yezixhobo okanye abaqhubi bangafumanekiyo. Xa kuvavanyelwa izinto ezikhutshwayo kwiradiyetha engenzelwanga ngabom, isidluliseli siya kufakwa kwimowudi yokufumana okanye imo yokungenzi nto, ukuba kunokwenzeka. Ukuba imo yokufumana kuphela ayinakwenzeka ngoko, unomathotholo uya kuba yi-passive (ekhethwayo) kunye/okanye ukuskena okusebenzayo. Kwezi meko, oku kuya kufuneka ukuba kuvuleleke umsebenzi kwi-BUS yonxibelelwano (okt, PCIe, SDIO, USB) ukuqinisekisa ukuba ukujikelezwa kweradiyetha ngokungeyonjongo kuvuliwe. Iilabhoratri zovavanyo zinokufuna ukongeza ukuthomalalisa okanye izihluzi ngokuxhomekeke kumandla omqondiso wazo naziphi na iibhikhoni ezisebenzayo (ukuba ziyasebenza) ukusuka kwi(ii)rediyo ezivuliweyo. Jonga i-ANSI C63.4, ANSI C63.10, kunye ne-ANSI C63.26 ngeenkcukacha ezingaphezulu zovavanyo ngokubanzi.
   Imveliso ephantsi kovavanyo isetelwe kwikhonkco/unxulumano kunye nesixhobo sobambiswano, njengokusetyenziswa kwesiqhelo okucetywayo kwemveliso. Ukunciphisa uvavanyo, imveliso ephantsi kovavanyo isetelwe ukusasaza kumjikelo womsebenzi ophezulu, njengokuthumela file okanye usasaza umxholo othile wemidiya.

Isilumkiso seFCC:
Naluphi na utshintsho okanye uhlengahlengiso olungavunywanga ngokucacileyo liqela elinoxanduva lokuthotyelwa lunokuphelisa igunya lomsebenzisi lokusebenzisa isixhobo. Esi sixhobo sithobela inxalenye ye-15 yeMithetho yeFCC. Ukusebenza kuxhomekeke kwezi meko zimbini zilandelayo: (1) Esi sixhobo asinakubanga luphazamiso luyingozi, kwaye (2) Esi sixhobo kufuneka samkele naluphi na uphazamiseko olufunyenweyo, kubandakanywa uphazamiseko olunokubangela usetyenziso olungafunekiyo.
