EBYTE E49-900M20S is a cost-effective wireless data transmission module launched by Chengdu Ebyte. It is a pure hardware module based on CMT2300A. E49-900M20S supports a maximum transmit power of 20dBm, and users can set a lower output power to save power consumption. Works in the 850MHz~930MHz frequency band, including the commonly used 868MHz and 915MHz frequency bands. This module is a pure RF transceiver module and uses an SPI interface, so it requires an MCU driver. Using an IPEX/stamp hole antenna, long-distance transmission up to 3 kilometers can be achieved.
