E77-915MBH-01 Kit de développement et d'évaluation de la série E77
[Interface d'alimentation]：USB
[Interface de communication]：TTL
[Fréquence]：915 MHz
[Dimensions]：65 *30 mm
[Introduction]：La carte de développement E77-915MBH-01 est un modèle d'entrée de gamme équipé du module LoRaWAN haute puissance E77-915M30S. Ce kit d'évaluation offre toutes les fonctionnalités du module, est livré avec le firmware du protocole LoRaWAN préinstallé et la plupart des broches du module sont accessibles via des connecteurs latéraux, permettant ainsi aux développeurs de connecter facilement divers périphériques à l'aide de cavaliers. Cette carte de développement peut également être utilisée sur une plaque d'essai.
