MicoAir LR900-P with 5dBi Antenna

The MicoAir LR900-P is a 900MHz LoRa telemetry radio for ArduPilot and PX4 flight controllers, giving long-range fixed-wing, agriculture and long-range FPV builds a reliable link well beyond typical 2.4GHz telemetry range.

Key features

• Sold as a matched pair of radio modules for a complete point-to-point ground-to-air link.
• 1000mW (30dBm) transmit power on the 890-915MHz band, with a rated range of up to 50km.
• LoRa modulation with frequency-hopping spread spectrum for strong interference resistance.
• Transparent serial transmission works with Mavlink and other protocols, not just ArduPilot/PX4 telemetry.
• USB-C (CP2102) interface is plug-and-play with QGroundControl on Android as well as a PC.

• Data rate: 3.2 KB/s down, 1.6 KB/s up
• Antenna connector: SMA (female)

Because it shares the 900MHz band, pair it with a 2.4GHz RC link rather than a 915MHz receiver to avoid interference; the box includes two 5dBi antennas and flight-controller cables for MicoAir405/743 and Pixhawk boards.
