[Introduction]：E108-GN03D est un module de positionnement et de navigation par satellite multimode hautes performances, hautement intégré, à faible consommation et à faible coût, basé sur la solution AT6558R. Il peut être utilisé dans les applications de positionnement et de navigation GNSS telles que la navigation des véhicules, les appareils portables intelligents. et les drones. Il prend en charge GPS/BDS/GNSS/GLONASS, est de petite taille, a une faible consommation d'énergie et fournit des interfaces logicielles et matérielles compatibles avec d'autres fabricants de modules, réduisant considérablement le cycle de développement de l'utilisateur. Il prend également en charge plusieurs façons de se connecter à d'autres périphériques, prenant en charge les interfaces UART et GPIO. Si des interfaces I2C et SPI sont requises, elles peuvent être personnalisées.
