Introduction
The E290-M/EWM290-M series are high-performance SMD ChirpIoT™ wireless modules designed for the 433MHz and 470MHz bands. By adopting the PAN3060 as the module core, both anti-interference performance and communication range have been further enhanced. Thanks to the innovative ChirpIoT™ modulation technology, these modules significantly outperform FSK and GFSK modulation products in terms of anti-interference capability and communication distance. The modules are primarily targeted at smart home, wireless meter reading, scientific research, medical applications, and medium-to-long range wireless communication devices, featuring an industrial-grade high-precision 32MHz crystal oscillator. The three module variants differ in package and output power, and as pure RF transceiver modules, they require MCU-based control or a dedicated SPI debugging tool.
Features
