[Introduction]:E290-400MM20S is an ultra-small chip independently developed based on PANCHIP's new generation of domestic RF chip PAN3060, suitable for 433MHz, 470MHz ChirpIoTTM wireless modules. Using PAN3060 as the core, the new ChirpIoT TM modulation technology far exceeds the current FSK and GFSK modulation products. This module is targeted at smart homes, wireless meter reading, scientific research and medical treatment, and medium and long-distance wireless communication equipment, and uses industrial-grade high-precision 32MHz crystal oscillators.
