Kuphelileview
I-ESP32 -WROOM -32E iyimojula enamandla, ejwayelekile ye-WiFi -BT -BLE MCU eqondise inhlobonhlobo yezinhlelo zokusebenza, kusukela kumanethiwekhi ezinzwa ezinamandla amancane kuya emisebenzini edingeka kakhulu, njengombhalo wekhodi wezwi, ukusakaza umculo kanye nokuqopha i-MP3. Lena i-SMD Module enothi lwe-PCB engu-2.4 GHz ebhodini. Igcina isekethe yokulungisa engu-π yokufanisa i-antenna impedance. Inawo wonke ama-GPIO ku-pin -out ngaphandle kwalawo asevele asetshenziselwe ukuxhuma i-flash. I-module yokusebenza voltage ingaba yibanga ukusuka ku-3.0 V ukuya ku-3.6 V. Ibanga lemvamisa lingu-2400 MHz ukuya ku-2483.5 MHz. I-40 MHz yangaphandle njengomthombo wewashi wohlelo. Kukhona ne-flash ye-SPI engu-4 MB yokugcina izinhlelo zabasebenzisi nedatha. Ulwazi loku-oda lwe-ESP32 -WROOM -32E luhlelwe kanje:

- Ulwazi lwamamodi okuhlola kanye nezidingo zokuhlola ezengeziwe
a)Isidlulisi semojuli sihlolwe ngokugcwele ngumnikezeli wemojula enanini elidingekayo lamashaneli, izinhlobo zokuguquguquka, nezindlela, akufanele kudingeke ukuthi isifaki sokusingatha sihlole kabusha zonke izindlela zokusakaza ezitholakalayo noma izilungiselelo. Kunconywa ukuthi umkhiqizi womkhiqizo osingethe, afake isidlulisi semojuli, enze izilinganiso ezithile zophenyo ukuze aqinisekise ukuthi uhlelo oluyinhlanganisela oluwumphumela aluweqi 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 abasingathi akumele bacabange ukuthi ngenxa yokuthi isidlulisi semojuli siqinisekisiwe ukuthi abanaso isibopho sokuthobela umkhiqizo wokugcina.
c)Uma uphenyo lubonisa ukukhathazeka kokuthobela umkhiqizi ophethe umkhiqizo 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 wokuzihlangula wengxenye Yengxenye B Umsingathi wokugcina/inhlanganisela yemojuli idinga ukubuyekezwa ngokuqhathanisa nemibandela ye-FCC Ingxenye 15B yamarediyetha angahlosiwe ukuze agunyazwe ngokufanelekile ukuthi asebenze njengedivayisi yedijithali Ingxenye 15.
Isexwayiso se-FCC:
Noma yiziphi Izinguquko noma ukuguqulwa okungagunyazwanga ngokucacile yinhlangano enesibopho sokuthobela imithetho kungasusa igunya lomsebenzisi lokusebenzisa okokusebenza. Le divayisi ithobela ingxenye 15 yeMithetho ye-FCC. Ukusebenza kungaphansi kwezimo ezimbili ezilandelayo: (1) Lolu cingo angeke lubangele ukuphazamiseka okuyingozi, futhi (2) Lolu cingo kufanele lwamukele noma yikuphi ukuphazamiseka okutholiwe, okuhlanganisa ukuphazamiseka okungase kubangele ukusebenza okungafuneki.
