Kuphatikiza kwa Hardware

The MT0, Nordic based chipset, idzaphatikizidwa mu board board molingana ndi izi mu bukhuli: https://infocenter.nordicsemi.com/pdf/nRF52840_PS_v1.7.pdf *chonde pitani ku nordicsemi.com kuti mudziwe zambiri zaposachedwa. mafotokozedwe ndi malangizo ophatikiza.

Pin Ntchito
Chipangizo cha nRF52840 chimapereka kusinthasintha ponena za GPIO pin routing ndi kasinthidwe. Komabe, mapini ena ali ndi malire kapena malingaliro pamasinthidwe a pini ndi ntchito.

 

Chidziwitso Chotsatira cha FCC

Chipangizochi chimagwirizana ndi gawo 15 la malamulo a FCC. Kugwira 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.

Zipangizozi zayesedwa ndipo zapezeka kuti zikugwirizana ndi malire a chipangizo cha digito cha Gulu B, motsatira gawo 15 la Malamulo a FCC. Malire awa adapangidwa kuti apereke chitetezo chokwanira ku kusokoneza koyipa pakukhazikitsa nyumba. Chipangizochi chimapanga, chimagwiritsa ntchito komanso chimatha kuwunikira mphamvu zamawayilesi ndipo, ngati sichinayikedwe ndi kugwiritsidwa ntchito motsatira malangizo, chikhoza kusokoneza njira zolumikizirana ndi wailesi. Komabe, palibe chitsimikizo kuti kusokoneza sikudzachitika mu unsembe winawake. Ngati chipangizochi chikuyambitsa kusokoneza koopsa kwa wailesi kapena kulandila wailesi yakanema, komwe kungadziwike ndikuzimitsa ndi kuyatsa zida, wogwiritsa ntchito akulimbikitsidwa kukonza zosokoneza ndi chimodzi mwazinthu izi:

• Yankhanitsaninso kapena sinthani mlongoti wolandira.
• Wonjezerani kulekana pakati pa zida ndi wolandila.
• Lumikizani zidazo munjira yosiyana ndi yomwe wolandila amalumikizidwa.
• Funsani wogulitsa kapena wodziwa ntchito pa wailesi/TV kuti akuthandizeni.

FCC Chenjezo
Kusintha kulikonse kapena kusintha komwe sikunavomerezedwe ndi Meraki kungathe kulepheretsa wogwiritsa ntchito kugwiritsa ntchito chipangizochi. Transmitter iyi sayenera kukhala pamalo amodzi kapena kugwira ntchito molumikizana ndi mlongoti wina uliwonse kapena chotumizira.

FCC Radiation Exposure Statement
Chida ichi chimagwirizana ndi malire a FCC okhudzana ndi ma radiation omwe akhazikitsidwa kumalo osalamulirika. Zidazi ziyenera kuyikidwa ndikugwiritsidwa ntchito ndi mtunda wochepera 20 cm pakati pa radiator ndi thupi lanu. Chotumizira ichi sichiyenera kukhala pamalo amodzi kapena kugwira ntchito limodzi ndi mlongoti wina uliwonse kapena chotumizira.

Ndemanga ya Industry Canada
Chipangizochi chikugwirizana ndi RSS -247 ya Malamulo a Industry Canada. Kugwira ntchito kumadalira zinthu ziwiri izi:

1. Chipangizochi sichikhoza kuyambitsa kusokoneza kovulaza, ndi
2. Chipangizochi chiyenera kuvomereza kusokonezedwa kulikonse komwe kulandidwa, kuphatikiza kusokoneza komwe kungayambitse ntchito yosafunikira.

Industry Canada Radiation Exposure Statement
Chida ichi chimagwirizana ndi malire a IC radiation exposure yokhazikitsidwa pamalo osalamulirika. Zidazi ziyenera kuyikidwa ndikugwiritsidwa ntchito ndi mtunda wochepera 20 cm pakati pa radiator ndi thupi lanu.
