[Introduction]：E48-433M20S is a pure hardware, cost-effective wireless data transmission module developed by Chengdu Ebyte based on Huapu Microelectronics' CMT2310A chip solution. The wireless module supports a maximum transmit power of 20dBm, and users can set lower output power to reduce power consumption. The module works in the frequency band, covering the commonly used 433MHz frequency band. The module is a pure hardware RF transceiver module that uses an SPI interface and requires an external MCU driver.
