   Gawoli litha kugwiritsidwa ntchito pazida za IoT. Kulowetsa voltage ku gawoli ndi dzina la 3.3V-3.6 V DC. Kutentha kozungulira kwa gawoli ndi -40 °C ~ 65 °C. Ndi mlongoti wa PCB wokha womwe umaloledwa. Mlongoti wina uliwonse wakunja ndi woletsedwa.
3. Njira zochepa za module N/A
4. Tsatirani kapangidwe ka mlongotiN/A
5. Malingaliro okhudzana ndi RF
   Zipangizozi zimagwirizana ndi malire a FCC okhudzana ndi ma radiation omwe akhazikitsidwa kumalo osalamulirika. Zidazi ziyenera kuyikidwa ndikugwiritsidwa ntchito ndi mtunda wochepera 20cm pakati pa radiator ndi thupi lanu. Ngati zidazo zidapangidwa kuti zizigwiritsidwa ntchito ngati zosunthika, kuwunika kowonjezera kwa RF kungafunikire monga momwe 2.1093 yafotokozera.
6. Mlongoti
   Mtundu wa mlongoti: PCB mlongoti Kupeza pachimake: 3.40dBi Omni mlongoti wokhala ndi cholumikizira cha IPEX Peak gain2.33dBi
7. Zolemba ndi zotsatila
   Cholembera chakunja pamapeto a OEM chitha kugwiritsa ntchito mawu monga awa: "Muli Transmitter Module FCC ID: 2AC7Z-ESP32WROVERE" kapena "Muli FCC ID: 2AC7Z-ESP32WROVERE."
8. Zambiri zamitundu yoyesera ndi zofunikira zina zoyesera
   a) Ma modular transmitter ayesedwa mokwanira ndi wopereka ma module pa nambala yofunikira ya ma tchanelo, mitundu yosinthira, ndi mitundu, sikuyenera kukhala kofunikira kuti wokhazikitsayo ayeserenso mitundu kapena masinthidwe onse omwe alipo. Ndikoyenera kuti wopanga zinthu zochititsa, kuyika modular transmitter, ayese zofufuza kuti atsimikizire kuti makina ophatikizika omwe abwerawo sadutsa malire operekera zinthu zabodza kapena malire a m'mphepete mwa bandi (mwachitsanzo, pomwe mlongoti wina ukupangitsa kuti pakhale mpweya wowonjezera).
   b) Kuyesaku kuyenera kuyang'ana mpweya womwe ungachitike chifukwa cha kusakanikirana kwa mpweya ndi ma transmitters ena, ma dijiti, kapena mawonekedwe a chinthu chomwe chimabwera (mpanda). Kufufuza kumeneku ndikofunikira kwambiri pakuphatikiza ma transmitters angapo amtundu wa modular pomwe chiphasocho chimachokera pakuyesa aliyense wa iwo poyimirira yekha. Ndikofunika kuzindikira kuti opanga zinthu zochititsa chidwi sayenera kuganiza kuti chifukwa chotumizira modular ndi chovomerezeka kuti alibe udindo wotsatira zomaliza.
   c) Ngati kafukufuku akuwonetsa kutsatiridwa ndi zomwe wopanga akuyenera kuti achepetse vutolo. Zogulitsa zomwe zimagwiritsa ntchito ma modular transmitter zimatsatiridwa ndi malamulo onse aukadaulo komanso momwe amagwirira ntchito mu Ndime 15.5, 15.15, ndi 15.29 kuti asasokoneze. Wogwiritsa ntchito chipangizocho adzakakamizika kusiya kugwiritsa ntchito chipangizocho mpaka vutolo litakonzedwa .
9. Kuyesa kowonjezera, Gawo 15 Gawo Lalikulu B chodzikanira Chodzikanira chomaliza cholandira/magawo akuyenera kuwunikidwa molingana ndi mfundo za FCC Gawo 15B za ma radiator osafuna kuti athe kuloledwa kugwira ntchito ngati chida cha digito cha Gawo 15. Wophatikiza omwe akukhazikitsa gawoli muzinthu zawo akuyenera kuwonetsetsa kuti chophatikizika chomaliza chikugwirizana ndi zofunikira za FCC mwa kuunika kwaukadaulo kapena kuunika kwa malamulo a FCC, kuphatikiza magwiridwe antchito a transmitter, ndipo akuyenera kuloza malangizo mu KDB 996369. ndi certified modular transmitter, kuchuluka kwa kafukufuku wamakina ophatikizika kumafotokozedwa ndi lamulo mu Gawo 15.33(a)(1) kudzera (a)(3), kapena kuchuluka kwa chipangizo cha digito, monga momwe tawonetsera mu Gawo. 15.33(b)(1), kaya ndi kuchuluka kotani komwe kumafufuzidwa Poyesa chinthu cholandirira, ma transmitter onse ayenera kukhala akugwira ntchito. Ma transmitter amatha kuthandizidwa pogwiritsa ntchito madalaivala omwe amapezeka pagulu ndikuyatsa, kotero ma transmitters akugwira ntchito. Nthawi zina, kungakhale koyenera kugwiritsa ntchito bokosi loyimba laukadaulo (test set) pomwe zida 50 kapena madalaivala palibe. Poyesa zotulutsa kuchokera ku radiator mosakonzekera, chotumiziracho chimayikidwa munjira yolandirira kapena mopanda ntchito, ngati kuli kotheka. Ngati kulandila kokha sikungatheke, wailesiyi ikhala yokhazikika (yokondedwa) ndi/kapena kusanthula mwachangu. Pazifukwa izi, izi zingafunike kuti zitheke kugwira ntchito pa BUS yolumikizirana (ie, PCIe, SDIO, USB) kuwonetsetsa kuti ma radiator osakonzekera akuyatsidwa. Malo oyesera angafunikire kuwonjezera zochepetsera kapena zosefera kutengera mphamvu ya siginecha ya mabekoni aliwonse omwe akugwira ntchito (ngati kuli kotheka) kuchokera pamawayilesi oyatsa. Onani ANSI C63.4, ANSI C63.10, ndi ANSI C63.26 kuti mumve zambiri za kuyezetsa.
   Zogulitsa zomwe zikuyesedwa zimakhazikitsidwa kuti zikhale ulalo/mgwirizano ndi chipangizo cholumikizirana, malinga ndi momwe amagwiritsidwira ntchito nthawi zonse. Kuti muchepetse kuyezetsa, chinthu chomwe chikuyesedwa chimayikidwa kuti chifalikire pamlingo wapamwamba kwambiri, monga kutumiza file kapena kusakatula zina zapa media.

Chenjezo la FCC:
Kusintha kulikonse kapena kusintha komwe sikunavomerezedwe mwachindunji ndi gulu lomwe limayang'anira kutsata kungathe kulepheretsa wogwiritsa ntchito kugwiritsa ntchito zidazo. Chipangizochi chikugwirizana ndi gawo 15 la Malamulo a FCC. Kugwiritsa ntchito kumadalira zinthu ziwiri izi: (1) Chipangizochi sichingabweretse kusokoneza koopsa, ndipo (2) Chipangizochi chiyenera kuvomereza kusokoneza kulikonse komwe kumalandira, kuphatikizapo kusokoneza komwe kungayambitse ntchito yosayenera.
