Chithunzi cha ESP8266
Mndandanda wa malamulo omwe akugwiritsidwa ntchito ku FCC
Gawo la FCC 15.247
Malingaliro okhudzana ndi RF
Chipangizochi chikugwirizana ndi malire a FCC RF owonetsera ma radiation omwe akhazikitsidwa kumalo osalamulirika. Zidazi ziyenera kuyikidwa ndikugwiritsidwa ntchito ndi mtunda wochepera 20cm pakati pa radiator ndi gawo lililonse la thupi lanu.
Zolemba ndi zotsatila
Chilembo cha ID ya FCC pamakina omaliza ayenera kulembedwa "Muli ndi ID ya FCC:
2A54N-ESP8266” kapena “Muli ma transmitter module FCC ID: 2A54N-ESP8266”.
Zambiri zamitundu yoyesera ndi zofunikira zina zoyesera
Lumikizanani ndi Shenzhen HiLetgo E-Commerce Co., Ltd ipereka njira yoyeserera yodziyimira yokha. Kuyesa kowonjezera ndi chiphaso kungakhale kofunikira ngati kangapo
ma modules amagwiritsidwa ntchito mwatsopano.
Kuyesa kowonjezera, Gawo 15 Gawo B lodziletsa
Kuwonetsetsa kuti zikutsatira ntchito zonse zomwe sizimapatsirana, wopanga malowa ali ndi udindo wowonetsetsa kuti ma module akhazikitsidwa ndikugwira ntchito mokwanira. Za
example, ngati wolandira alendo adaloledwa kale kukhala radiator mosakonzekera pansi pa ndondomeko ya Supplier's Declaration of Conformity popanda gawo lovomerezeka la transmitter ndipo gawo lawonjezeredwa, wopanga makamu ali ndi udindo wowonetsetsa kuti gawoli litayikidwa ndikugwira ntchito, wolandirayo akupitirizabe. tsatirani Gawo 15B zofunikira zama radiator mwangozi. Popeza izi zingadalire tsatanetsatane wa momwe gawoli likugwirizanirana ndi wolandira, Shenzhen HiLetgo E-Commerce Co., Ltd idzapereka chitsogozo kwa wopanga alendo kuti atsatire zofunikira za Gawo 15B.
Chenjezo la FCC
Chipangizochi chikugwirizana ndi Gawo 15 la Malamulo a FCC. Kugwira ntchito kumadalira zinthu ziwiri izi:
(1) Chipangizochi sichikhoza kuyambitsa kusokoneza kovulaza, ndipo (2) chipangizochi chiyenera kuvomereza kusokoneza kulikonse komwe kumalandira, kuphatikizapo kusokoneza komwe kungayambitse ntchito yosayenera.
ZINDIKIRANI 1: Kusintha kulikonse kapena kusintha kwa gawoli komwe sikunavomerezedwe mwachindunji ndi gulu lomwe limayang'anira kutsata kungathe kulepheretsa wogwiritsa ntchito kugwiritsa ntchito zidazo.
Ndemanga ya FCC Radiation Exposure:
Chida ichi chikugwirizana ndi malire a FCC owonetsera ma radiation omwe akhazikitsidwa kumalo osalamulirika. Ogwiritsa ntchito kumapeto ayenera kutsatira malangizo enieni ogwiritsira ntchito kuti akwaniritse kutsatiridwa ndi RF.
Zindikirani 1: Module iyi ndi yovomerezeka kuti ikugwirizana ndi zofunikira za RF pazikhalidwe za foni kapena zokhazikika, gawoli liyenera kukhazikitsidwa pama foni a m'manja kapena osakhazikika.
Chida cham'manja chimatanthauzidwa ngati chipangizo chotumizira chomwe chimapangidwa kuti chizigwiritsidwa ntchito m'malo ena osakhazikika komanso kuti chizigwiritsidwa ntchito m'njira yoti mtunda wolekanitsa wa masentimita 20 nthawi zambiri usungidwe pakati pa mawonekedwe a ma transmitter ndi thupi. za ogwiritsa ntchito kapena anthu oyandikana nawo. Zida zotumizira zomwe zimapangidwira kuti zigwiritsidwe ntchito ndi ogula kapena ogwira ntchito zomwe zitha kukhazikitsidwanso mosavuta, monga zida zopanda zingwe zolumikizidwa ndi kompyuta yanu, zimatengedwa ngati zida zam'manja ngati zikwaniritsa zofunikira zolekanitsa za 20 centimita.
Chipangizo chokhazikika chimatanthauzidwa ngati chipangizo chomwe chimatetezedwa mwakuthupi pamalo amodzi ndipo sichikhoza kusunthira kumalo ena.
Zindikirani 2: Zosintha zilizonse zomwe zasinthidwa ku gawoli zidzathetsa Kupereka Chitsimikizo, gawoli limangokhala kuyika kwa OEM kokha ndipo siliyenera kugulitsidwa kwa ogwiritsa ntchito kumapeto, wogwiritsa ntchitoyo alibe malangizo amanja ochotsa kapena kukhazikitsa chipangizocho, mapulogalamu okhawo. kapena ndondomeko yogwiritsira ntchito idzayikidwa mu bukhu la wogwiritsa ntchito kumapeto kwa zinthu zomaliza.
Zindikirani 3: Gawoli litha kugwiritsidwa ntchito ndi mlongoti womwe umaloledwa. Mlongoti uliwonse womwe uli wamtundu womwewo komanso wopindulitsa wofanana kapena wocheperako ngati mlongoti womwe umaloledwa ndi radiator mwadala ukhoza kugulitsidwa ndi kugwiritsidwa ntchito ndi, radiator yadalayo.
Zindikirani 4: Pamsika wazinthu zonse ku US, OEM ikuyenera kuchepetsa njira zogwirira ntchito mu CH1 mpaka CH11 pagulu la 2.4G popereka zida zopangira pulogalamu ya firmware. OEM sidzapereka chida chilichonse kapena zambiri kwa wogwiritsa ntchito zokhuza kusintha kwa Domain Regulatory.
Maulaliki
Gawoli limathandizira mgwirizano wa IEEE802.11 b/g/n, stack wathunthu wa TCP/IP protocol. Ogwiritsa ntchito amatha kugwiritsa ntchito ma module owonjezera pa intaneti yomwe ilipo kale kapena kumanga a
osiyana network controller.
ESP8266 ndi ma SOC opanda zingwe ophatikizika kwambiri, opangidwira malo komanso opanga mapulatifomu opanda mphamvu. Imapereka mwayi wosayerekezeka woyika luso la Wi-Fi
mkati mwa machitidwe ena, kapena kugwira ntchito ngati pulogalamu yodziyimira yokha, yotsika mtengo kwambiri, komanso malo ochepa omwe amafunikira.
ESP8266 imapereka yankho lathunthu komanso lokhazikika pamanetiweki a Wi-Fi; itha kugwiritsidwa ntchito kuchititsa pulogalamuyo kapena kutsitsa maukonde a Wi-Fi kuchokera kwa wina
purosesa yogwiritsira ntchito.
ESP8266EX ikakhala ndi pulogalamuyi, imayambira mwachindunji kuchokera ku kuwala kwakunja. Ili ndi cache yophatikizika kuti ipititse patsogolo magwiridwe antchito pamapulogalamu otere.
Mosiyana, kutumikira ngati adaputala ya Wi-Fi, intaneti yopanda zingwe ikhoza kuwonjezeredwa ku mapangidwe aliwonse opangidwa ndi microcontroller ndi kugwirizanitsa kosavuta (SPI / SDIO kapena I2C / UART mawonekedwe).
ESP8266 ili m'gulu la WiFi chip yophatikizika kwambiri pamsika; imaphatikiza masinthidwe a mlongoti, RF balun, mphamvu ampLifier, phokoso lochepa limalandira ampzowunikira, zosefera, mphamvu
ma module oyang'anira, amafunikira maulendo akunja akunja, ndipo yankho lonse, kuphatikiza gawo lakutsogolo, lapangidwa kuti likhale ndi gawo laling'ono la PCB.
ESP8266 imaphatikizanso purosesa yowonjezereka ya Tensilica's L106 Diamond series 32-bit processor, yokhala ndi on-chip SRAM, kuwonjezera pa magwiridwe antchito a Wi-Fi. ESP8266EX nthawi zambiri
ophatikizidwa ndi masensa akunja ndi zida zina zogwiritsira ntchito pogwiritsa ntchito ma GPIO ake; zizindikiro za ntchito zotere zaperekedwa mu Eksamppafupi ndi SDK.
