Ujongano lonxibelelwano lwe-TTL lubonelelwe , Umsebenzisi-onobubele kushishino lwezixhobo ze-serial port uthungelwano, unikezelo lwamandla ombane lwamkela uluhlu olubanzi loyilo lokusetyenziswa kwamandla aphantsi(≤40uA@5V).

Itekhnoloji yeLoRa ngokwayo inobuntununtunu be-recei ephezulu kakhulu (RSSI) kunye

I-super signal-to-noise (SNR) kunye neteknoloji yethu yenkxaso yemodem kunye nokusebenza kwemveliso okuzinzileyo nokuthembekileyo.

Imodyuli ye-wireless ye-LoRa inamandla kakhulu okuthintela ukuphazamiseka.

I-MDL210 isebenzisana ne-4G DTU yenkampani yethu, enokuthi iququzelele ukusekwa kwesango le-LoRa ukuqonda ukuhanjiswa kwedatha okude.
