Chithunzi cha IC

Chipangizochi chikugwirizana ndi ma RSS opanda laisensi a Industry Canada. Kugwira ntchito kumadalira zinthu ziwiri izi:

• Chipangizochi sichikhoza kuyambitsa kusokoneza; ndi
• Chipangizochi chiyenera kuvomereza kusokonezedwa kulikonse, kuphatikizapo kusokoneza komwe kungayambitse ntchito yosayenera ya chipangizocho.

Chidziwitso Chokhudzana ndi Ma radiation
Zipangizozi zimagwirizana ndi malire a ma radiation a IC omwe amakhazikitsidwa m'malo osalamulirika. Zipangizozi ziyenera kukhazikitsidwa ndikugwiritsidwa ntchito osachepera 20 cm pakati pa radiator ndi thupi lanu.

Chipangizochi chimapangidwira ophatikiza a OEM okha pamikhalidwe iyi (Kugwiritsa ntchito gawo la chipangizo): 

• Mlongoti uyenera kukhazikitsidwa kotero kuti 20 cm imasungidwa pakati pa mlongoti ndi ogwiritsa ntchito, ndi
• Gawo la transmitter silingakhale limodzi ndi ma transmitter kapena mlongoti wina uliwonse.

Malingana ngati zinthu ziwiri pamwambapa zakwaniritsidwa, kuyesa kwina kwa transmitter sikudzafunikanso. Komabe, chophatikizira cha OEM chikadali ndi udindo woyesa zomwe apeza kumapeto kwa zofunikira zilizonse zofunika pakuyika gawoli.

ZOFUNIKA KWAMBIRI:

Ngati izi sizingakwaniritsidwe (mwachitsanzoampndi masanjidwe ena a laputopu kapena kusanjidwa ndi chotumizira china), ndiye kuti chilolezo cha Canada sichikuwonekanso chovomerezeka ndipo IC ID singagwiritsidwe ntchito pomaliza. Izi zikachitika, wophatikiza wa OEM adzakhala ndi udindo wowunikanso zomwe zatsirizidwa (kuphatikiza chotumizira) ndikupeza chilolezo chosiyana cha Canada.

Malizitsani Kulemba Zamalonda

Gawo la transmitter iyi ndi lololedwa kuti ligwiritsidwe ntchito pachida chomwe mlongoti ungayikidwe kotero kuti 20 cm ikhoza kusungidwa pakati pa mlongoti ndi ogwiritsa ntchito. Chomaliza chomaliza chiyenera kulembedwa pamalo owonekera ndi awa: "Lili ndi IC: 21098-ESPC3WROOM".

Zambiri Zamanja kwa Wogwiritsa Ntchito Mapeto

Wophatikizira wa OEM akuyenera kudziwa kuti asapereke zambiri kwa wogwiritsa ntchito za momwe angayikitsire kapena kuchotsa gawo la RF mu bukhu la wogwiritsa ntchito la chomaliza chomwe chimaphatikiza gawoli. Bukhuli likhala ndi zonse zofunikira pakuwongolera / chenjezo monga momwe zikuwonetsedwera m'bukuli.

Chowulutsira pawailesichi [IC:21098-ESPC3WROOM] chavomerezedwa ndi Innovation, Science and Economic De-velopment Canada kuti igwire ntchito ndi mitundu ya tinyanga tatchulidwa pansipa, ndikupeza phindu lalikulu lovomerezeka.

• Mtundu: Mlongoti wa PCB pa bolodi
• Kulemera: 3.26 dBi
• Kulowetsa kwa Antenna Impedance50ohm

Mitundu ya tinyanga tating'ono yomwe sinaphatikizidwe pamndandandawu yomwe ili ndi phindu lalikulu kuposa kuchuluka komwe kwawonetsedwa pamtundu uliwonse womwe watchulidwa ndizoletsedwa kugwiritsidwa ntchito ndi chipangizochi.
