MK-LM-01H LoRaWAN Module Specification

Kev Piav Qhia Luv:

Lub module MK-LM-01H yog ib lub module LoRa uas tsim los ntawm Suzhou MoreLink raws li STMicroelectronics' STM32WLE5CCU6 chip. Nws txhawb nqa tus qauv LoRaWAN 1.0.4 rau EU868/US915/AU915/AS923/IN865/KR920/RU864 zaus bands, nrog rau CLASS-A/CLASS-C node hom thiab ABP/OTAA network access methods. Tsis tas li ntawd, lub module muaj ntau hom low-power thiab siv tus qauv UART rau kev sib txuas lus sab nraud. Cov neeg siv tuaj yeem teeb tsa nws yooj yim ntawm AT commands kom nkag mus rau tus qauv LoRaWAN networks, ua rau nws yog ib qho kev xaiv zoo rau cov ntawv thov IoT tam sim no.
