[Introduction]：E610-900T20S is a high-speed continuous transmission 433M wireless data transmission module developed by Ebyte, with built-in high-performance microcontroller and wireless transceiver chip. Working in the 850~870MHz, 902~928MHz frequency bands (default 900MHz), the transmit power is 20dBm. It is suitable for scenarios that require rapid transmission of large amounts of data, such as high-speed sensing, surveying, mapping, measurement and control, remote sensing positioning, etc.
