HELTEC AUTOMATION 2A2GJHTIT Wi-Fi BLE nodi ya LoRa
Mawu Oyamba
The Wireless Stick ndi gulu la Arduino logwirizana ndi netiweki (LoRa, WiFi, Bluetooth). Ndi ultra mini size, yokwanira mu boardboard yokhazikika (yokhala), Kawonedwe kakang'ono ka 64 * 32 OLED ndi Lithium Battery Management (yokhala ndi socket ya SH1.25-2P) imasonkhanitsidwanso. Ndilo chisankho chabwino kwambiri pakukulitsa projekiti yanu ya IoT. Wireless Stick inali ndi RF yoyenderana bwino, yopereka chizindikiro chabwino komanso chokhazikika cha RF. Timaperekanso laibulale ya Arduino ya stack ya LoRaWAN, imapangitsa kuti ilumikizane mwachindunji ndi chipata chilichonse cha LoRa kudzera pa protocol ya LoRaWAN. Chip chachikulu chowongolera cha mankhwalawa ndi Xtensa LX6 32bit dual-core purosesa: ESP32. CPU yamphamvu, imapereka wailesi ya WiFi ya BLE komanso yapamwamba kwambiri.

Development chilengedwe unsembe
Kuyika kwa driver
Kwa Mac OS, Ubuntu, Windows 7 kapena pamwamba pa opareting'i sisitimu, dalaivala amangoyikiratu, ngati sanayikidwe kapena kupangitsidwa cholakwika, chonde pitani kwa Silicon Labs official webTsamba lotsitsa ndikuyika mtundu waposachedwa wa dalaivala: adilesi yotsitsa ya CP210X (Monga tidayesa, tidapeza kuti dalaivala wa CP210x chip version 6.7.0.0 ndiye wokhazikika kwambiri. Mtunduwu ndiwolimbikitsidwa kwambiri: ulalo wotsitsa) Ku makina opangira a Windows, mwachitsanzoample, ngati galimotoyo yaikidwa, mukhoza mu "Device Manager - port" kuti muwone uthenga wofanana:
Development chilengedwe unsembe
Ntchito zonse zimatengera kuti kompyuta yanu idayika Arduino IDE yatsopano kwambiri. Bungwe lachitukuko cha Wireless Stick ndi la HelTec WIFI Kit. Kuti muyike malo achitukuko, chonde onani malo a chitukuko cha Heltec WIFI Kit:Njira yaposachedwa yoyika yaikidwa pa adilesi iyi. http://www.heltec.cn/the-installation-method-of-wifi-kit-series-products-in-arduino-development-environment/?lang=en Ngati zonse zili bwino, mutha kupeza bolodi lachitukuko cha Wireless Stick pagulu la Zida - Development Board. Monga momwe chithunzi 2-1 chikusonyezera:
Mutha kupeza ma board a Arduino pazinthu zosiyanasiyana mu "Examples” menyu, yomwe mutha kupanga mwachindunji ndikutsitsa ku board yanu yachitukuko ya WIFI Kit. Kusamala ndi lolingana chitukuko chachitukuko chitsanzo, kusankha chitsanzo cholakwika kungachititse kusonkhanitsa zolakwika. Monga momwe chithunzi 2-2 chikusonyezera: 
Zida
- Chidule cha Mafunso Ambiri
- Laibulale ya ESP32-LoRaWAN Arduino https://github.com/HelTecAutomation/ESP32_LoRaWAN Kuti mupewe kukopera kwa bolodi, kuti mugwiritse ntchito nambala ya ESP32-LoRaWAN mufunika laisensi yokhudzana ndi Chip ID ya board yanu:
http://www.heltec.cn/search/ - Kukula ndi kujambula kwa 3D
- Kukula kwa board ya AutoCAD 2004: Tsitsani
- SolidWorks 2014 mtundu wa 3D kujambula: Tsitsani Kuti mudziwe zambiri, chonde pitani www.heltec.cn
Zindikirani
- Wireless Stick ili ndi soketi ya batri ya SH1.25-2P Lithium, mungafunike waya wamba wa SH1.25 kuti mulumikizane ndi batire.
- Ntchito yolumikizirana ya LoRa ya Wireless Stick iyenera kugwiritsidwa ntchito ndi mlongoti wokhala ndi ma frequency oyenera. Ngati palibe mlongoti, chipangizo cha LoRa chikhoza kuwonongeka. Mawonekedwe a IPEX amasiyidwa pa bolodi lachitukuko, koma mlongoti ulibe zida. Chonde gulani mlongoti padera.

Zowonjezera 
Chithunzi cha FCC
Zidazi 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 sichinayikidwe ndikugwiritsidwa ntchito motsatira malangizo, chikhoza kuyambitsa kusokoneza kwa mawayilesi. Komabe, palibe chitsimikizo kuti kusokoneza sikudzachitika mu unsembe winawake. Ngati chida ichi chikuyambitsa kusokoneza koyipa kwa wailesi kapena kulandila wailesi yakanema, komwe kungadziwike ndikuzimitsa ndi kuyatsa zida, wogwiritsa ntchitoyo akulimbikitsidwa kuyesa kusokoneza ndi chimodzi kapena zingapo mwa izi:
- Yankhanitsaninso kapena sinthani mlongoti wolandira.
- Wonjezerani kulekana pakati pa zida ndi wolandila.
- Lumikizani chipangizocho munjira yosiyana ndi yomwe wolandila amalumikizidwa.
- Funsani wogulitsa kapena wodziwa ntchito pa wailesi/TV kuti akuthandizeni.
Kutsimikizira kutsatiridwa kosalekeza, zosintha zilizonse kapena zosinthidwa zomwe sizinavomerezedwe mwachindunji ndi chipani. Kukhala ndi udindo wotsatira kukhoza kulepheretsa wogwiritsa ntchito kugwiritsa ntchito chipangizochi. (EksampLe- gwiritsani ntchito zingwe zotchinga zokhazokha polumikizana ndi kompyuta kapena zida zotumphukira). Chipangizochi chikugwirizana ndi Gawo 15 la Malamulo a FCC. Kugwiritsa ntchito kumadalira zinthu ziwiri izi: Chipangizochi sichingabweretse kusokoneza kovulaza, ndipo Chipangizochi chiyenera kuvomereza kusokoneza kulikonse komwe kumalandira, kuphatikizapo kusokoneza komwe kungayambitse ntchito yosayenera.
Ndemanga ya FCC Radiation Exposure:
Zipangizozi zimagwirizana ndi FCC Radiation exposure limits zokhazikitsidwa mosasamala za chilengedwe. Zidazi ziyenera kuyikidwa ndikugwiritsidwa ntchito ndi mtunda wochepera 20cm pakati pa radiator ndi thupi lanu.
