[Introduction]：E290-400MM20S est une puce ultra-petite développée indépendamment sur la base de la nouvelle génération de puce RF PAN3060 de PANCHIP, adaptée aux modules sans fil ChirpIoTTM 433 MHz, 470 MHz. En utilisant le PAN3060 comme noyau, la nouvelle technologie de modulation ChirpIoT TM dépasse de loin les produits de modulation FSK et GFSK actuels.
