CDEBYTE E220900T22D LoRa LLCC68 850 930MHz 22dBm UART SMA K

Introducing the CDEBYTE E220900T22D LoRa LLCC68 module — a compact, high-performance LoRa spread-spectrum wireless UART module designed around the LLCC68 chipset. Operating in the 850.125–930.125 MHz band (default 873.125 MHz), it delivers up to 22 dBm transmit power and reliable long-range links of up to 5 km. The TTL-level UART interface is compatible with both 3.3 V and 5 V IO, making it easy to integrate with microcontrollers and embedded systems. Its small 21 × 36 mm footprint and SMA K antenna connector simplify hardware design for IoT, industrial monitoring, and asset tracking applications. Certified CE, FCC, and RoHS, with origin in Mainland China and model E220-900T22D-V1.2.

Benefits & Tips

• Long-range LoRa capability: up to 5 km in favorable conditions, ideal for remote sensing and outdoor monitoring.
