CDEBYTE E22 400T37S LoRa 433MHz Module 37dBm Long Range 25KM
CDEBYTE E22-400T37S LoRa 433MHz Module is a compact, high-power LoRa transceiver designed for long-range IoT connectivity. Operating at 433.125 MHz with up to 37 dBm output power, this module delivers reliable links over impressive distances—up to 25 km in open terrain—while staying power-efficient for battery-powered deployments. The E22-400T37S leverages LoRa modulation for robust performance in noisy environments, making it ideal for remote sensing, agricultural telemetry, asset tracking, and smart metering. Packaged in a convenient SMD form factor with an IPEX antenna interface and stamp-through mounting options, it simplifies integration into compact PCBs and automated assembly. With features like Listen-Before-Talk (LBT) and RSSI monitoring, it helps you meet regulatory requirements and optimize link quality across diverse regions. New from CDEBYTE and manufactured in Mainland China, it’s ready for quick deployment in your next IoT project.
Benefits & Tips
