[Introduction]:La série EWM35T-2G4T06SP représente une nouvelle génération de modules série sans fil 2,4 GHz résistants aux hautes températures, conçus par Ebyte. Fonctionnant dans la bande de fréquences 2400–2480 MHz, ces modules sont dotés d'un boîtier standard de type « stamp-hole » (SMD) et d'une interface UART, ce qui facilite leur développement et leur utilisation. Ils prennent en charge diverses fonctionnalités telles que la transmission sans fil transparente, la transmission point à point, la diffusion (broadcast), la mise à jour du micrologiciel via le port série et le chiffrement des communications ; des services de développement sur mesure sont également proposés.
