[Introduction]：The E291 series is a pure hardware module based on the PAN3120 chip from Panqi Microelectronics. It supports a maximum transmit power of 30dBm, operates in the 410~510MHz frequency band, and features small size, low power consumption, and long communication distance. It is suitable for smart homes, wireless meter reading, scientific research and medical applications, as well as medium and long-range wireless communication applications. Since this module is a pure RF transceiver module, it requires an MCU driver or a dedicated SPI debugging tool.
