Gabatarwar samfur
An tsara Arduino MKR WAN 1300 don samar da mafita mai amfani da tsada ga masana'antun da ke neman ƙara haɗin haɗin LoRaR zuwa ayyukan su tare da ƙarancin ƙwarewar sadarwar. Ya dogara ne akan samfuran Atmel SAMD21 da Murata CMWX1ZZABZLo-Ra.
Zane ya haɗa da ikon yin amfani da jirgi ta amfani da baturan 1.5V AA ko AAA ko 5V na waje. Canjawa daga wannan tushe zuwa wani ana yin ta atomatik. Kyakkyawan ikon kwamfuta na 32-bit mai kama da allon MKR ZERO, yawancin kayan haɗin gwiwar I / O mai arziƙi, sadarwar LoRa 8 mai ƙarancin ƙarfi, da sauƙin amfani da software na Arduino (IDE) don haɓaka lambar da shirye-shirye. Duk waɗannan fasalulluka sun sa hukumar ta dace da buƙatun ayyukan da ke da ƙarfin baturi na iot a cikin ƙaramin tsari. Ana iya amfani da tashar USB don kunna allo (5V). Arduino MKRWAN 1300 na iya aiki tare da ko ba tare da haɗe baturi ba kuma tare da iyakancewar wutar lantarki.
Dole ne a yi amfani da MKR WAN 1300 tare da eriyar GSM wacce za a iya haɗawa da allon ta hanyar haɗin UFL kaɗan. Da fatan za a duba cewa zai iya karɓar mitoci a cikin kewayon LoRa (433/868/915 MHz).
Da fatan za a kula: Don samun sakamako mai kyau, kar a haɗa eriya zuwa saman ƙarfe kamar chassis na mota
Ƙarfin baturi: Batir ɗin da aka haɗa dole ne ya kasance yana da ƙarancin ƙarfin lantarki na 1.5V
Mai Haɗin Baturi: Idan kana son haɗa fakitin baturi (2xAA ko AAA) zuwa MKRWAN 1300, yi amfani da screw terminals.
Polarity: Kamar yadda siliki a kasan allon ya nuna, madaidaicin fil shine mafi kusanci da mai haɗin USB
Vin: Ana iya amfani da wannan fil ɗin don kunna jirgin ta hanyar samar da wutar lantarki na 5V. Idan ana ba da wutar lantarki ta wannan fil, wutar USB ta katse. Wannan ita ce kawai hanyar da za ku iya ciyar da 5v (kewayon 5V zuwa iyakar 6V) zuwa allon ba tare da amfani da USB ba. fil ɗin shigarwa ne.
5V: Lokacin da aka kunna shi daga mai haɗin USB ko fil ɗin VIN na allo, wannan fil ɗin yana fitar da 5V daga allon. Ba a tsara shi ba kuma ana ɗaukar wutar lantarki kai tsaye daga shigarwar.
VCC: Wannan fil ɗin yana fitar da 3.3V ta hanyar mai sarrafa onboard. Wannan ƙarfin lantarki shine 3.3V lokacin amfani da USB ko VIN, wanda yayi daidai da jerin batura biyu lokacin amfani.
LED yana haskakawa: Ana haɗa wannan LED ɗin zuwa shigarwar 5V daga USB ko VIN. Ba a haɗa shi da ƙarfin baturi. Wannan yana nufin yana haskakawa lokacin da wutar lantarki ke fitowa daga USB ko VIN, amma yana tsayawa lokacin da allon yana amfani da ƙarfin baturi. Wannan yana ƙara girman amfani da kuzarin da aka adana a cikin baturi. Saboda haka, a yanayin da LED ON ba shi da haske, abu ne na al'ada don barin allon kewayawa ya dogara da wutar lantarki don aiki akai-akai.
