MicoAir LR900 915MHz LoRa Long-Range Telemetry Module

The MicoAir LR900 is a 915MHz LoRa telemetry radio built for ArduPilot and PX4 flight controllers, giving a small, low-cost bidirectional data link between the aircraft and ground station software.

Key features

• LoRa modulation with frequency-hopping spread spectrum for resilient long-range data transmission.
• Sold as a matched pair of the chosen model (two LR900-F or two LR900-P units), one on the aircraft and one at the ground station.
• Auto-connects on power-up with no configuration needed for standard Mission Planner or QGroundControl use.
• Available with a compact 2dBi or a high-gain 5dBi antenna to match your mission requirements.
