[Introduction]：E90-DTU (400SL30L) est une radio de transmission de données sans fil utilisant la technologie de modulation LoRa de qualité militaire. Il dispose d'une variété de méthodes de transmission et fonctionne dans la bande de fréquences (410,125 ~ 493,125 MHz) (par défaut 433,125 MHz). La radio fournit deux types de port de communication série RS485 et TTL, prend en charge l'alimentation cc 8 ~ 28 V ou l'entrée d'alimentation de la batterie au lithium 4,2 V, prend en charge la charge à courant constant inverse.
