915MHz LoRa RF Module E22 900T22S Transmitter Receiver RSSI

The 915MHz LoRa RF Module E22-900T22S from CDEBYTE is a compact, high-performance SMD transceiver that combines transmitter and receiver functions with RSSI monitoring for reliable long‑range wireless links. Designed for IoT, remote sensing, and M2M applications, this module delivers robust performance in a small 16 × 26 mm package and communicates easily via UART. With a broad operating band around 900 MHz and a max output of 22 dBm, it provides strong links even in challenging environments.

Benefits & Tips

• Long-range capability: Up to 5000 m in open air with maximum power and proper antenna, making it ideal for field deployments and remote monitoring.
• Easy integration: UART interface paired with a compact SMD footprint simplifies PCB design and quick prototyping. Powerable from 3.3 to 5.5 V to fit most MCU systems.
• Flexible antenna options: Supports IPEX or stamp-hole antennas for versatile placements and easy matching to your enclosure or device.
