I-MK-LM-01H LoRaWAN Module Imininingwane

Incazelo emfushane:

Imodyuli ye-MK-LM-01H iyimodyuli ye-LoRa eklanywe yi-Suzhou MoreLink esekelwe ku-chip ye-STM32WLE5CCU6 ye-STMicroelectronics. Isekela indinganiso ye-LoRaWAN 1.0.4 yama-frequency band e-EU868/US915/AU915/AS923/IN865/KR920/RU864, kanye nezinhlobo zama-node e-CLASS-A/CLASS-C kanye nezindlela zokufinyelela kunethiwekhi ye-ABP/OTAA. Ngaphezu kwalokho, imodyuli inezindlela eziningi zamandla aphansi futhi isebenzisa i-UART ejwayelekile yezixhumi zokuxhumana zangaphandle. Abasebenzisi bangayilungisa kalula ngemiyalo ye-AT ukuze bafinyelele amanethiwekhi ajwayelekile e-LoRaWAN, okwenza kube ukukhetha okuhle kakhulu kwezinhlelo zokusebenza zamanje ze-IoT.

三. Ubukhulu Bemishini kanye Nezincazelo Zephini

3.1 Umdwebo Wobukhulu Bohlaka

Inothi

Ubukhulu obungenhla buyizilinganiso zedokhumenti zomklamo wesakhiwo. Ukuze kuvunyelwe amaphutha onqenqemeni lwe-PCB, ubude nobubanzi obuphawuliwe buyi-14*20mm. Sicela ushiye isikhala esanele ku-PCB. Inqubo yesembozo sokuvikela iwukubumba okuhlanganisiwe kwe-SMT (Surface Mount Technology). Uma ithintekile ukuphakama kwe-solder, ubukhulu bayo bangempela busukela ku-2.7mm kuya ku-2.8mm.
