- Antenna Connection: Batanidza antenna yakakodzera ye868MHz kana 915MHz kune IPEX connector kana stamp gomba. Iva nechokwadi chekuti antenna impedance inoenderana ne50 Ohm impedance yemodule.
- Environmental Zvinotarisirwa: Module iyi yakagadzirirwa kushanda munzvimbo dzinobva -40°C kusvika 85°C. Zvisinei, dzivisa kuchinja-chinja kwekushisa kwakanyanya uye hunyoro hwakawanda.
- ESD Dziviriro: Module iyi ine dziviriro yeESD. Zvisinei, gara uchitevera matanho akajairwa eESD paunenge uchibata zvikamu zvemagetsi.
3.2 Module Zvimiro
- Module yeRF yakavakirwa mukati, PA (Simba) Amplifier), LNA (Ruzha Rwakaderera Amplifier), sefa yeSAW (Surface Acoustic Wave), uye sefa yeceramic kuti ishande zvakanaka.
- Chinodziya chekristaro chine temperature-compensated crystal oscillator (32MHz) chine hunyanzvi hwepamusoro-soro hunoita kuti frequency ishande zvakanaka patembiricha yakakura.
- Inoshandisa machipisi matsva eSX1262/SX1268 kuti ishande zvakanaka, irambe iri kure, ikurumidze kushandisa data, uye iite kuti ive diki kana tichienzanisa nezvizvarwa zvekare.

Mufananidzo 8: Kuenzanisa kugadzikana kwefrequency ne crystal oscillator yakanyatsogadzirwa
4. Operating Instructions
Kana yangobatanidzwa musystem yako, module inoshanda seLoRa transceive device. Kuronga kwe host microcontroller kunodiwa kuti utonge module kuburikidza neSPI interface yayo.
4.1 Basic Operation
- Kutanga: Gadzira marejista emodule kuburikidza neSPI kuti uise maparameter akadai semafrequency ekushanda, spreading factor, bandwidth, uye coding rate.
- Transmission: Isa data mu "transmit buffer" yemodule wobva watanga "transmission". Module iyi ichange ichishanda ne "LoRa modulation" uye "RF transmission".
- Reception: Gadzira module kuti iwane reception. Ichateerera mapaketi eLoRa anouya pane frequency yakatarwa uye ma parameter. Data rakagamuchirwa rinogona kuverengwa kubva ku receiver buffer yemodule kuburikidza neSPI.
- Power Management: Shandisa mamodhi ane simba shoma (kana achitsigirwa neSX1262/SX1268 chip uye ari mufirmware yako) kuchengetedza simba mumapurogiramu anoshandisa bhatiri.
Kuti uwane ruzivo rwakadzama nezvemapurogiramu uye marongero erejista, tarisa pepa redata reSX1262/SX1268 uye chero maguidhi epurogiramu eEBYTE aripo kana maraibhurari.
5. Kuchengeta
Mamodule aya akagadzirirwa kuvimbika kwenguva refu uye kazhinji anoda kugadziriswa kushoma. Zvisinei, kutevedzera tsika dzakanaka kunogona kuwedzera hupenyu hwawo uye kuona kuti anoshanda zvakanaka.
- Utsanana: Chengeta module isina guruva, tsvina, uye hunyoro. Shandisa bhurasho rakapfava, rakaoma kana mhepo yakamanikidzwa yekuchenesa kana zvichidikanwa.
- Environmental Control: Shandisa module mukati memazinga ayo ekupisa nehunyoro. Dzivisa kusangana nezvinhu zvinoparadza.
- Connection Kutendeseka: Nguva nenguva tarisa zvese zvinobatanidzwa, kunyanya zvinobatanidzwa neantenna, kuti zvionekwe kuti zvakamira zvakanaka here uye kuti hazvina kukuvara here.
- Firmware Dzokorora: Kana EBYTE ikaburitsa zvigadziriso zvefirmware zvemodule (zvinowanzo shandiswa kuburikidza ne host microcontroller), funga nezvekuzvishandisa kuti ubatsirwe nekuvandudzwa kana kugadziriswa kwezvikanganiso.
6. Kugadzirisa matambudziko
Kana ukasangana nematambudziko neLoRa module yako, funga nezvematanho anotevera ekugadzirisa matambudziko:
- Hapana Kukurukurirana:
- Simbisa simba remagetsitage uye kugadzikana.
- Tarisa kubatana kweSPI (MOSI, MISO, SCK, CS) uye iva nechokwadi chekuti zvakabatana zvakanaka uye zvinoshanda.
- Simbisa gadziriro yeSPI yemugadziri we microcontroller (mode, kumhanya kwewachi).
- Iva nechokwadi chekuti module yatanga nemazvo mufirmware yako. - Hunhu Hwakashata hweSignali/Hunhu Hwakashata:
- Tarisa kubatana kweantenna uye iva nechokwadi chekuti yakabatana zvakanaka uye haina kukuvara.
- Iva nechokwadi chekuti antenna yakakodzera mashandiro emodule (868MHz kana 915MHz).
- Iva nechokwadi chekuti hapana zvinokanganisa pakati pekutumira nekugamuchira mamodule.
- Tarisa kana paine kukanganiswa kweRF yemunharaunda.
- Simbisa simba rekutumira uye gamuchira marongero ekunzwisisa mu firmware. - Module Overheating:
- Iva nechokwadi chekuti huwandu hwezvinhu zviripotage haipfuure 5.5V.
- Tarisa simba remagetsi rinobuda uchienzaniswa nezvinodiwa (610mA ye868M30S, 640mA ye915M30S). Kudhonza simba remagetsi kwakawandisa kunogona kuratidza kukanganisa kana kuti gadziriro isiriyo. - Intermittent Operation:
- Tarisa kana paine ma connections asina kusimba kana ma cold solder joints.
- Iva nechokwadi chekuti magetsi akasimba uye haana ruzha.
- Review firmware yako yezvinetso zvenguva kana mamiriro emujaho.
7. Mazano emushandisi
- Antenna Yekunze: Kuti uwane kutaurirana kwakakodzera, shandisa antenna yekunze ine simba rakakodzera uye iva nechokwadi chekuti yakaiswa kure nezvimwe zvikamu zvemagetsi nezvinhu zvesimbi.
- Kusefa Kwemagetsi: Funga nezvekuwedzera mamwe ma "power supply filtering" (semuenzaniso, ma "capacitor") pedyo nema "power pins" e "module" kuti uve nechokwadi chekuti magetsi akachena, kunyanya munzvimbo dzine ruzha.
- Maraibhurari eSoftware: Tsvaga maraibhurari eLoRaWAN kana LoRa aripo ekushandisa puratifomu yako ye microcontroller yawakasarudza. Izvi zvinogona kurerutsa kukura kwedata.
- Regulatory Compliance: Zivai mitemo yemuno maererano nekubuda kwesimba reRF uye kushandiswa kwemafrequency munharaunda yenyu kuti muve nechokwadi chekuti mashandiro anoenderana nezvinodiwa.
8. Warranty uye Tsigiro
Kana muine rutsigiro rwehunyanzvi, zvichemo zvewarandi, kana mibvunzo ine chekuita neEBYTE E22P-868M30S neE22P-915M30S LoRa Wireless Modules, ndapota taurai nemutengesi, Rui Electronics Store, zvakananga kuburikidza nepuratifomu yamakatenga.
