I-Arduino Yangempela MKR WAN 1300 ABX00017 Dipole Antenna GSM X000016

Isingeniso somkhiqizo

I-Arduino MKR WAN 1300 yakhelwe ukuhlinzeka ngesixazululo esisebenzayo nesingabizi kakhulu kubakhiqizi abafuna ukwengeza ukuxhumeka kwe-LoRaR kumaphrojekthi abo abanolwazi oluncane lokuxhumana. Isekelwe kumamojula we-Atmel SAMD21 kanye ne-Murata CMWX1ZZABZLo-Ra.

Umklamo uhlanganisa ikhono lokunika amandla ibhodi usebenzisa amabhethri amabili angu-1.5V AA noma AAA noma i-5V yangaphandle. Ukushintsha usuka komunye umthombo uye komunye kwenziwa ngokuzenzakalelayo. Amandla amahle ekhompuyutha angama-32-bit afana nebhodi le-MKR ZERO, isethi evame ukucebile ye-I/O interfaces, ukuxhumana okunamandla aphansi kwe-LoRa 8, kanye nokusetshenziswa kalula kwesofthiwe ye-Arduino (IDE) ekuthuthukisweni kwekhodi nokuhlela. Zonke lezi zici zenza ibhodi lifanelekele amaphrojekthi anamandla ebhethri e-iot avelayo ngendlela encane. Imbobo ye-USB ingasetshenziselwa ukunika amandla ibhodi (5V). I-Arduino MKRWAN 1300 ingasebenza noma ngaphandle kwebhethri enamathiselwe futhi isebenzisa amandla alinganiselwe.

I-MKR WAN 1300 kufanele isetshenziswe nothi lwe-GSM olungaxhunywa ebhodini ngesixhumi esincane se-UFL. Sicela uhlole ukuthi ingamukela amafrikhwensi ebangeni le-LoRa (433/868/915 MHz).

Sicela uqaphele: Ukuze uthole imiphumela emihle, unganamathiseli uthi endaweni yensimbi efana ne-chassis yemoto

Umthamo webhethri: Ibhethri elixhunyiwe kufanele libe ne-voltage yegama elingu-1.5V

Isixhumi Sebhethri: Uma ufuna ukuxhuma iphakethe lebhethri (2xAA noma AAA) ku-MKRWAN 1300, sebenzisa amatheminali ngezikulufu.

I-polarity: Njengoba kukhonjiswe usilika phansi ebhodini, iphinikhodi ephozithivu iseduze kakhulu nesixhumi se-USB.

I-Vin: Le phinikhodi ingasetshenziswa ukunika amandla ibhodi ngogesi olawulwayo ongu-5V. Uma amandla anikezwa ngale phini, ukunikezwa kwamandla kwe-USB kuyanqanyulwa. Lena ukuphela kwendlela ongondla ngayo i-5v (ububanzi obungu-5V ukuya ku-6V esiphezulu) ebhodini ngaphandle kokusebenzisa i-USB. Iphinikhodi okokufaka.

I-5V: Uma inikwe amandla kusuka kusixhumi se-USB noma iphinikhodi ye-VIN yebhodi, le phinikhodi ikhipha i-5V ebhodini. Ayilawulwa futhi i-voltage ithathwa ngokuqondile kokufakwayo.

I-VCC: Le phinikhodi ikhipha i-3.3V nge-onboard regulator. Le voltage ingu-3.3V uma usebenzisa i-USB noma i-VIN, elingana nochungechunge lwamabhethri amabili uma usebenzisa.

I-LED iyakhanyisa: Le LED ixhumeke kokokufaka okungu-5V okuvela ku-USB noma i-VIN. Ayixhunyiwe emandleni ebhethri. Lokhu kusho ukuthi iyakhanyisa lapho amandla evela ku-USB noma ku-VIN, kodwa ihlala ivaliwe lapho ibhodi isebenzisa amandla ebhethri. Lokhu kukhulisa ukusetshenziswa kwamandla agcinwe ebhethrini. Ngakho-ke, esimweni lapho i-LED ON ingakhanyi, kuyinto evamile ukuvumela ibhodi lesifunda lithembele ekunikezeni amandla ebhethri ukuze lisebenze ngokujwayelekile.
