Nkọwapụta Modulu LoRaWAN MK-LM-01H

Nkọwa Dị Mkpirikpi:

Modulu MK-LM-01H bụ modulu LoRa nke Suzhou MoreLink mere dabere na mgbawa STM32WLE5CCU6 nke STMicroelectronics. Ọ na-akwado ọkọlọtọ LoRaWAN 1.0.4 maka eriri ugboro EU868/US915/AU915/AS923/IN865/KR920/RU864, yana ụdị node CLASS-A/CLASS-C na ụzọ nnweta netwọk ABP/OTAA. Na mgbakwunye, modulu ahụ nwere ọtụtụ ụdị ike dị ala ma na-anabata UART ọkọlọtọ maka njikọ nkwukọrịta mpụga. Ndị ọrụ nwere ike ịhazi ya ngwa ngwa site na iwu AT iji nweta netwọk LoRaWAN ọkọlọtọ, na-eme ka ọ bụrụ nhọrọ magburu onwe ya maka ngwa IoT dị ugbu a.
