SGW2828 LoRa Kōwae AT Whakahau
Kupu Whakataki
Ko te SGW2828 LoRa Module he SoM kua whakamanahia i mua i te whakamana i te hononga LoRa mo nga punaha whakauru kawe me te iti rawa te mana. Ko te SGW2828 Kōwae kiato, tino tairongo ka eke ki te kaha +30dBm Tx me te kore e hiahia ki te whakauru i te hiko o waho. amphe mea whakarite mo te maakete o Amerika me te auau whakahaere o te 915MHz me te kaha tere tere. Ma te tautoko i te whanuitanga o nga pukoro me te awhe ultra-roa horahia nga korero awhi i waenga i nga taputapu, ka taea te whakauru i te SGW2828 Module ki roto i nga momo papahanga whanaketanga rongonui kia tere te hanga o nga taputapu atamai i te utu papai. 
Ko tenei pukapuka a te kaiwhakamahi e whakaatu ana i te huinga whakahau AT e tautokohia ana e te SGW2828 LoRa Module.
