Fa'amatalaga o le MK-LM-01H LoRaWAN Module

Fa'amatalaga Pupuu:

O le module MK-LM-01H o se module LoRa na mamanuina e Suzhou MoreLink e faʻavae i luga o le chip STM32WLE5CCU6 a le STMicroelectronics. E lagolagoina le tulaga masani a le LoRaWAN 1.0.4 mo fusi o taimi faʻaonaponei a le EU868/US915/AU915/AS923/IN865/KR920/RU864, faʻapea foʻi ma ituaiga o node CLASS-A/CLASS-C ma auala e ulufale ai i fesoʻotaʻiga ABP/OTAA. E le gata i lea, o loʻo iai i le module le tele o auala e maualalo le malosi ma faʻaaogaina se UART masani mo fesoʻotaʻiga i fafo. E faigofie ona faʻatulaga e tagata faʻaoga e ala i poloaiga AT e maua ai fesoʻotaʻiga masani a le LoRaWAN, ma avea ai ma filifiliga sili ona lelei mo talosaga IoT o loʻo iai nei.

1.2Vaega

1.Maxima le malosiaga e fa'asalalauina e o'o atu i le 20.8dBm, e lagolagoina ai le fetu'una'iga o polokalama faakomepiuta ma le fetu'una'iga o le ADR.
2. Fa'ailoga pu mo le faigofie o le fa'apipi'iina.
3. O pine uma o le chip e ta'ita'iina i fafo, e fa'afaigofie ai le atina'eina lona lua.
4. Lautele le lautele o le sapalai o le voltage, e lagolagoina ai le sapalai o le eletise mai le 1.8V i le 3.6V.
