Hardware Integration

Iyo MT0, Nordic based chipset, ichabatanidzwa mubhodhi rekugamuchira zvinoenderana neanotevera maratidziro mugwaro iri: https://infocenter.nordicsemi.com/pdf/nRF52840_PS_v1.7.pdf * ndokumbira ushanyire nordicsemi.com kune yazvino tsanangudzo uye kubatanidza mirayiridzo.

Pini Mabasa
Iyo nRF52840 mudziyo inopa shanduko maererano neGPIO pin routing uye kumisikidza. Nekudaro, mamwe mapini ane zvipimo kana kurudziro yepini masisitimu uye mashandisiro.

FCC Kutevedzera Chirevo

Ichi chishandiso chinoenderana nechikamu 15 chemitemo yeFCC. Kushanda kunoenderana nemamiriro maviri anotevera: (1) Chigadzirwa ichi hachigone kukonzera kukanganisa kunokuvadza, uye (2) mudziyo uyu unofanirwa kugamuchira chero kukanganisa kwakagamuchirwa, kusanganisira kukanganisa kunogona kukonzera kushanda kusingade.

Midziyo iyi yakaedzwa ikawanikwa ichitevedzera miganho yeClass B yedhijitari, zvichienderana nechikamu chegumi nemimwe cheMitemo yeCCC. Iyi miganho yakagadzirirwa kupa dziviriro inonzwisisika kubva mukukanganiswa kweinokuvadza mukugadziriswa kwekugara. Midziyo iyi inogadzira, inoshandisa uye inogona kuburitsa radio frequency simba uye, kana isina kuiswa uye ikashandiswa zvinoenderana nemirairidzo, inogona kukonzera kukanganisa kwekutaurirana kweredhiyo. Nekudaro, hapana vimbiso yekuti kupindira hakuzoitika mune kumwe kuiswa. Kana chishandiso ichi chikakanganisa kukanganisa kune redhiyo kana kugamuchirwa kweterevhizheni, izvo zvinogona kutsanangurwa nekudzima michina nekumira, mushandisi anokurudzirwa kugadzirisa kukanganiswa neimwe yeanotevera matanho:

Reorrent kana kutamisa antenna inogamuchira.
Wedzera kupatsanurwa pakati pemidziyo nemugamuchiri.
Batanidza midziyo mune yekubuda padunhu rakasiyana kubva kune iyo inogamuchira yakabatana.

Bvunza mutengesi kana nyanzvi yeredhiyo/TV ine ruzivo kuti ubatsirwe.

FCC Kuchenjerera
Chero shanduko kana gadziridzo dzisina kutenderwa zvakajeka naMeraki dzinogona kukanganisa mushandisi simba rekushandisa mudziyo uyu. Iyi Transmitter haifanirwe kunge yakabatana kana kushanda pamwe chete nechero imwe antenna kana transmitter.

FCC Radiation Exposure Statement
Mudziyo uyu unoenderana neFCC radiation exposure miganho yakatemerwa nharaunda isingadzoreki. Mudziyo uyu unofanirwa kuisirwa uye kushanda nehudiki hunhambwe 20 cm pakati pe radiator nemuviri wako. Iyi transmitter haifanirwe kunge yakabatana kana kushanda pamwe chete nechero imwe antenna kana transmitter.

Industry Canada Chirevo
Ichi chishandiso chinoenderana neRSS -247 yeIndasitiri Canada Mitemo. Kushanda kunoenderana nemamiriro maviri anotevera:

Ichi chishandiso chinogona kusakonzera kukanganisa kunokuvadza, uye
Muchina uyu unofanirwa kugamuchira chero kukanganisa kunowanikwa, kusanganisira kukanganisa kunogona kukonzera kushanda kwausingadi.

Industry Canada Radiation Exposure Statement
Mudziyo uyu unoenderana neIC radiation exposure miganho yakatemerwa nharaunda isingadzoreki. Mudziyo uyu unofanirwa kuisirwa uye kushanda nehudiki hunhambwe 20 cm pakati pe radiator & nemuviri wako.
