Tilmaamaha Module-ka LoRaWAN ee MK-LM-01H

Sharaxaad Gaaban:

Module-ka MK-LM-01H waa module LoRa ah oo ay samaysay Suzhou MoreLink oo ku salaysan chip-ka STM32WLE5CCU6 ee STMicroelectronics. Waxay taageertaa heerka LoRaWAN 1.0.4 ee xargaha soo noqnoqda ee EU868/US915/AU915/AS923/IN865/KR920/RU864, iyo sidoo kale noocyada qanjidhada CLASS-A/CLASS-C iyo hababka marin u helidda shabakadda ABP/OTAA. Intaa waxaa dheer, module-ku wuxuu leeyahay qaabab badan oo awood yar wuxuuna qaataa UART caadi ah oo loogu talagalay is-dhexgalka isgaarsiinta dibadda. Isticmaalayaashu si fudud ayay ugu habeyn karaan amarrada AT si ay u galaan shabakadaha caadiga ah ee LoRaWAN, taasoo ka dhigaysa doorasho aad u fiican codsiyada IoT ee hadda jira.

Qeexitaannada Biinanka iyo Cabbirrada Farsamada

3.1 Sawirka Cabbirka Dulucda

Fiiro gaar ah

Cabbirrada kor ku xusan waa cabbirrada dukumeentiga ee loogu talagalay naqshadaynta qaab-dhismeedka. Si loogu oggolaado khaladaadka cidhifyada goynta PCB, cabbirrada dhererka iyo ballaca ee la calaamadeeyay waa 14 * 20mm. Fadlan meel ku filan uga tag PCB-ga. Habka daboolka gaashaanka waa qaabaynta tooska ah ee SMT (Tiknoolajiyadda Buurta Dhulka) oo isku dhafan. Iyada oo ay saamayso dhererka alxanka, dhumucdiisuna waxay u dhaxaysaa 2.7mm ilaa 2.8mm.

Fiiro gaar ah 1: Biinanka PA6 iyo PA7 waxaa loo isticmaalaa sidii beddelka RF ee gudaha ee moduleka, halkaas oo PA6 = RF_TXEN iyo PA7 = RF_RXEN. Marka RF_TXEN=1 iyo RF_RXEN=0, waa kanaalka gudbinta; marka RF_TXEN=0 iyo RF_RXEN=1, waa kanaalka helitaanka. Fiiro gaar ah 2: Biinanka PC14-OSC32_IN iyo PC15-OSC32_OUT waxay leeyihiin oscillator kiristaal ah oo 32.768KHz ah oo gudaha ku xiran module-ka, kaas oo loo dooran karo isticmaalayaasha inta lagu jiro horumarinta labaad. Fiiro gaar ah 3: Biinanka OSC_IN iyo OSC_OUT waxay leeyihiin oscillator kiristaal ah oo 32MHz ah oo gudaha ku xiran module-ka, kaas oo loo dooran karo isticmaalayaasha inta lagu jiro horumarinta labaad.
