Original Arduino MKR WAN 1300 ABX00017 Dipole Antenna GSM X000016

Chiyambi cha malonda

Arduino MKR WAN 1300 idapangidwa kuti ipereke njira yothandiza komanso yotsika mtengo kwa opanga omwe akufuna kuwonjezera kulumikizana kwa LoRaR kumapulojekiti awo omwe ali ndi chidziwitso chochepa chapaintaneti. Zimatengera ma module a Atmel SAMD21 ndi Murata CMWX1ZZABZLo-Ra.

Mapangidwewo akuphatikizapo kuthekera koyendetsa bolodi pogwiritsa ntchito mabatire awiri a 1.5V AA kapena AAA kapena 5V yakunja. Kusintha kuchokera ku gwero lina kupita ku lina kumachitika zokha. Mphamvu yabwino yamakompyuta ya 32-bit yofanana ndi bolodi ya MKR ZERO, yomwe nthawi zambiri imakhala yolemera ya ma I/O, kulumikizana kwamphamvu kwa LoRa 8, komanso kugwiritsa ntchito pulogalamu ya Arduino (IDE) popanga ma code ndi mapulogalamu. Zonsezi zimapangitsa gululo kukhala loyenera pulojekiti yoyendetsedwa ndi batri ya iot mu mawonekedwe ang'onoang'ono. Doko la USB litha kugwiritsidwa ntchito kupatsa mphamvu bolodi (5V). Arduino MKRWAN 1300 imatha kugwira ntchito kapena popanda batire yolumikizidwa komanso kugwiritsa ntchito mphamvu zochepa.

MKR WAN 1300 iyenera kugwiritsidwa ntchito ndi mlongoti wa GSM womwe ungathe kulumikizidwa pa bolodi kudzera pa cholumikizira chaching'ono cha UFL. Chonde onani kuti ikhoza kuvomereza ma frequency mumtundu wa LoRa (433/868/915 MHz).

Chonde dziwani: Kuti mupeze zotsatira zabwino, musamangirire mlongoti pamalo achitsulo monga chassis yagalimoto

Kuchuluka kwa batri: Batire yolumikizidwa iyenera kukhala ndi mphamvu yamagetsi ya 1.5V

Cholumikizira Battery: Ngati mukufuna kulumikiza paketi ya batri (2xAA kapena AAA) ku MKRWAN 1300, gwiritsani ntchito zomangira.

Polarity: Monga zikuwonetseredwa ndi silika pansi pa bolodi, pini yabwino ili pafupi kwambiri ndi cholumikizira cha USB.

Vin: Pini iyi itha kugwiritsidwa ntchito kupatsa mphamvu bolodi kudzera pamagetsi oyendetsedwa ndi 5V. Ngati mphamvu yaperekedwa kudzera pa pini iyi, magetsi a USB amachotsedwa. Iyi ndi njira yokhayo yomwe mungadyetse 5v (osiyanasiyana 5V mpaka 6V) ku bolodi popanda kugwiritsa ntchito USB. Pini ndi cholowetsa.

5V: Ikayendetsedwa kuchokera ku cholumikizira cha USB kapena pini ya VIN ya bolodi, pini iyi imatulutsa 5V kuchokera pa bolodi. Ndizosayendetsedwa ndipo voteji imatengedwa mwachindunji kuchokera pazolowera.

VCC: Pini iyi imatulutsa 3.3V kudzera pa boardboard regulator. Mphamvu iyi ndi 3.3V mukamagwiritsa ntchito USB kapena VIN, yomwe ndi yofanana ndi mabatire awiri angapo mukamagwiritsa ntchito.

Kuwala kwa LED: LED iyi imalumikizidwa ndi kulowetsa kwa 5V kuchokera ku USB kapena VIN. Sichilumikizidwa ndi mphamvu ya batri. Izi zikutanthauza kuti zimawunikira pamene mphamvu ikuchokera ku USB kapena VIN, koma imakhalabe pamene bolodi ikugwiritsa ntchito mphamvu ya batri. Izi zimakulitsa kugwiritsa ntchito mphamvu zosungidwa mu batri. Choncho, ngati LED ON si yowala, ndi zachilendo kulola gulu la dera kudalira mphamvu ya batri kuti igwire ntchito bwino.
