Bayanin Module na MK-LM-01H LoRaWAN
Takaitaccen Bayani:
Module ɗin MK-LM-01H wani tsari ne na LoRa wanda Suzhou MoreLink ya tsara bisa guntuwar STM32WLE5CCU6 ta STMicroelectronics. Yana goyan bayan ma'aunin LoRaWAN 1.0.4 don tashoshin mita na EU868/US915/AU915/AS923/IN865/KR920/RU864, da kuma nau'ikan node na CLASS-A/CLASS-C da hanyoyin samun hanyar sadarwa ta ABP/OTAA. Bugu da ƙari, tsarin yana da hanyoyi da yawa masu ƙarancin ƙarfi kuma yana amfani da UART na yau da kullun don hanyoyin sadarwa na waje. Masu amfani za su iya saita shi cikin sauƙi ta hanyar umarnin AT don samun damar hanyoyin sadarwa na LoRaWAN na yau da kullun, wanda hakan ya sa ya zama kyakkyawan zaɓi ga aikace-aikacen IoT na yanzu.
