Ngā Whakatakotoranga o te MK-LM-01H LoRaWAN Module

Whakaahuatanga Poto:

Ko te kōwae MK-LM-01H he kōwae LoRa i hangaia e Suzhou MoreLink i runga i te maramara STM32WLE5CCU6 a STMicroelectronics. E tautoko ana i te paerewa LoRaWAN 1.0.4 mō ngā roopu auau EU868/US915/AU915/AS923/IN865/KR920/RU864, tae atu ki ngā momo pūnga CLASS-A/CLASS-C me ngā tikanga urunga whatunga ABP/OTAA. Hei tāpiri, he maha ngā momo aratau mana-iti o te kōwae, ā, e whakamahi ana i te UART paerewa mō ngā atanga whakawhitiwhiti kōrero o waho. Ka taea e ngā kaiwhakamahi te whirihora ngāwari mā ngā whakahau AT hei uru atu ki ngā whatunga LoRaWAN paerewa, ā, he kōwhiringa pai rawa atu mō ngā tono IoT o nāianei.

Ko ngā inenga o runga ake nei ko ngā inenga tuhinga mō te hoahoa hanganga. Hei ārai i ngā hapa tapahi PCB, ko ngā inenga roa me te whānui kua tohua ko 14*20mm. Waiho he wāhi nui ki runga i te PCB. Ko te tukanga hipoki parepare he mea hanga tika mā te SMT (Surface Mount Technology). Ka pāngia e te teitei o te tūhono, ko tōna matotoru tuturu kei waenga i te 2.7mm ki te 2.8mm.
