I-MK-LM-01H LoRaWAN Module Specifikaton

Inkcazo emfutshane:

Imodyuli ye-MK-LM-01H yimodyuli ye-LoRa eyilwe yiSuzhou MoreLink esekelwe kwitshiphu ye-STM32WLE5CCU6 ye-STMicroelectronics. Ixhasa umgangatho we-LoRaWAN 1.0.4 weebhendi ze-frequency ze-EU868/US915/AU915/AS923/IN865/KR920/RU864, kunye neentlobo zeenode ze-CLASS-A/CLASS-C kunye neendlela zokufikelela kwinethiwekhi ye-ABP/OTAA. Ukongeza, le modyuli ineendlela ezininzi zamandla aphantsi kwaye isebenzisa i-UART esemgangathweni kwiindlela zonxibelelwano zangaphandle. Abasebenzisi banokuyicwangcisa ngokulula ngemiyalelo ye-AT ukufikelela kwiinethiwekhi ze-LoRaWAN ezisemgangathweni, nto leyo eyenza ukuba ibe lukhetho oluhle kakhulu kwiisicelo zangoku ze-IoT.
