E49-400M20S4 Ebyte wireless data transmission Pure hardware module Low output power SPI communication interface [IC]：CMT2300A [Frequency]：410~510MHz [Power]：20dBm [Distance]：2.5km [Size]：16*16mm [Product weight]：0.9±1g [Introduction]：E49-400M20S4 is a cost-efective wireless data transmission module launched by Chengdu Ebyte. It is a pure hardware module based on CMT2300A.E49- 400M20S4 supports a maximum transmit power of 30dBm, and users can set a lower output power to save power consumption. The module works in the .433/470MHz frequency band. With small size and low power consumption. Since this module is a pure RF transceiver module, it needs to be driven by an MCU or adedicated SPI debugging tool. Send Inquiry Purchase File DownloadsCompare Specification Parameters Pin Definition Order Way File Downloads Series Products Main parameter Min.
